It's been a while, but now we're back with our brand new IBM XIV Host Attachment Kit 2.0.0!
You probably noticed that we made the jump to version 2.0.0, and for a very good reason: We have an exciting new feature we've been developing for the last 6 months - xiv_host_profiler.
xiv_host_profiler introduces a new approach in the way we provide support to hosts connected to XIV systems. The utility gathers information about your host's configuration, analyzes it against a set of best-practice rules, and enables pre-emptive identification of storage connectivity problems. And this is exactly why we recommend running it on a regular basis.
This feature is also tightly integrated into our latest XIV System release 11.2. By default, when using xiv_host_profiler, the collected information gets uploaded to your XIV System for further analysis. This ability will assist our technicians to ensure your hosts' health before commencing XIV System upgrades or other procedures.
For privacy reasons, the information collected by xiv_host_profiler is only related to your host's storage connectivity status - items such as the host's HBA model, installed OS version and the configuration state of the multi-path framework.
After collecting the information, xiv_host_profiler is also able to analyze it against a bundled set of rules:
The rules against which we analyze the host's configuration will be updated regularly and can be downloaded from Fix Central.
As mentioned before, it's best to run xiv_host_profiler at least once a week (in order to keep the data as up-to-date as possible). We provide an easy way to do so - simply run 'xiv_host_profiler --create-scheduled-task'.
As usual, you can read more about xiv_host_profiler (and other HAK utilities) in the Host Attachment Guide and Release Notes, as well as in the man pages included in the HAK package (how? simply run 'man xiv_host_profiler').
We believe HAK 2.0.0 and the included xiv_host_profiler will further improve on the way we support our storage systems and the hosts connected to them. We'd love to hear more from you about your needs and expectations in the comments.
In the meantime, you can download yourself a copy of the Host Attachment Kit for your favorite host's operating system, right here.

Hi Everyone !
It's HAK release time again !!
As part of our ongoing efforts to keep the IBM XIV Host Attachment Kit up to date and provide enhanced and new functionality, we are proud to announce the latest Host Attachment Kit version 1.9.0.
In this new version we have added support for several new platform versions:
Solaris 11, the recently released Red Hat Enterprise Linux 6.3 and the latest AIX 5.3, AIX 6.1 and AIX 7.1 Service Packs which introduce IBM XIV LUN 0 support.
But we did more than that. We have also enhanced the current HAK functionality by providing our UNIX & Linux users with manual pages accessible by using the 'man' command. Now you can access the documentation for each HAK command by executing 'man <HAK command>'.
In addition, in AIX OS, 'xiv_attach' is now capable of automatic discovery of connected XIV systems and host definition on the connected XIV, by utilizing the latest AIX 5.3, AIX 6.1 and AIX 7.1 SP, in which XIV LUN0 support was added. This aligns the XIV support in AIX OS with that of other supported OS-s. Moreover, LUN0 support also introduces a new HAK utility to AIX HAK users - 'xiv_syslist' , which you can read more about here.
The log collection utility, 'xiv_diag', was enhanced and now can be executed in unattended mode by providing the command with the destination path for the compressed log collection package as a command line argument.
Finally, additional bugs and known issues were resolved, and you can read more about them in the Release Notes.

We worked hard and it finally happened! Our own IBM XIV Storage Replication Adapter (SRA), version 2.2.2 is fully certified to operate with the following releases of the VMware vCenter Site Recovery Manager: 5.5, 5.5 Update1, 5.8, 6.0 and 6.1. Although this version is considered a minor release, making the SRA work with all the latest SRM versions was a challenging goal, involving a battery of compatibility tests and closely tied cooperation between the IBM and VMware interoperability teams.
Time to do some XIV mirroring :).
We’ve recently released a new version of the Storage Enabler for Windows Failover Clustering. As you may know, it is a software agent that runs as a Microsoft Windows Server service on two geographically dispersed cluster nodes, providing failover automation for IBM XIV storage provisioning on these nodes, and enabling deployment of these nodes in a geo-cluster configuration.
The new version, 1.2.0, is mainly a maintenance release that resolves some previous limitations and provides support for the new IBM XIV and Microsoft Windows Server versions that have been released since version 1.1.0.
So, what's new in version 1.2.0? Here are the main things:
Support for Microsoft Windows 2012 R2
Support for XIV microcode versions 11.2, 11.3 and 11.4
Support for post-migrated Hyper-Scale Mobility volumes (supported in XIV microcode version 11.3 or later)
The IBM Hyper-Scale Mobility feature is used for online migration of volumes from one XIV storage system to another (for more detailed information, see "IBM XIV Storage System: IBM Hyper-Scale Mobility Overview and Usage" here: http://www.redbooks.ibm.com/abstracts/redp5007.html).
An important note to make is that previous IBM Storage Enabler versions (1.1.0 or earlier) could not be used to protect volumes that have been migrated through the Hyper-Scale Mobility feature. In such cases, you could no longer use the IBM Storage Enabler with these volumes.
Now, version 1.2.0 of the IBM Storage Enabler resolves this limitation by allowing protection after the final migration state (after performing ‘End Proxy’). Starting from this version, the IBM Storage Enabler can be reconfigured with the migrated volume and resume its protection in just a few steps.
Here is what you will need to do before the protection of the IBM Storage Enabler can be resumed on the migrated volume:
First, upgrade the IBM Storage Enabler on all the cluster nodes to version 1.2.0. Then, remove from the cluster any XIV volume that you want to migrate with Hyper-Scale Mobility. Once removed from the cluster, you can start the migration of these volumes.
When the migration process is complete, ensure that the original XIV proxy volume (which was migrated) is removed from the original XIV storage system. Also ensure that a mirror relationship between the source and XIV destination volumes exists.
You can then add the migrated XIV volumes back to the MSCS cluster.
Finally, run the following commands to add the XIV mirror resource dependency to the newly added (migrated) volumes, and to verify the configuration:
That’s it. As always, we are happy to receive any feedback!

In this post we would like to introduce the latest version of the IBM Storage Driver for OpenStack, which we released on January 31st, 2013.
If by any chance you are unfamiliar with OpenStack, check out the official OpenStack project website at: www.openstack.org
To put in a few words, OpenStack is an open-source software platform for building private and public cloud environments. The IBM driver is a software component that enables storage provisioning of the IBM XIV Storage Systems in OpenStack cloud environments.
The latest IBM driver version was preceded by an earlier one (1.1.0), which enabled basic storage provisioning operations, such as volume creation and deletion from OpenStack Cinder Node, and volume attachment to OpenStack VMs.
The new release (1.1.1) further enhances the integration between OpenStack and IBM XIV Storage System by adding support for XIV volume snapshot functions.
For example, let's look at the following OpenStack Web UI management page:
In this example, if you want to create a snapshot of ‘vol1’ on IBM XIV Storage System, you can use the ‘Create Snapshot’ action using either OpenStack CLI or Web UI.
Here is your created snapshot, as can be viewed from the XIV GUI:
Similarly, you can use OpenStack's ‘Create volume from snapshot’ action to create a volume based on an existing snapshot.
An additional ease-of-use enhancement in version 1.1.1 is the new unattended installation option, allowing no user interaction during the installation, perfect for automating the installation process. You can use the following command format to install the IBM driver in an unattended mode:
Cinder-node# ./install.sh –s –a <xiv_address> –u <username> –p <password> –o <pool_name>
The IBM Storage Driver for OpenStack can be downloaded here along with the Installation Guide and Release Notes.
Whenever you choose to integrate your IBM XIV Storage System with an OpenStack cloud environment, our driver is available to help you achieve this goal. We are happy to provide this newer version that further facilitates and enhances the utilization of your XIV storage resources and capabilities in your cloud environment.
As always, you are welcome to share your thoughts with us.

We're pleased to announce the release of the new IBM DS8000 Storage Replication Adapter version - 2.3.1. As you know, IBM DS8000 Storage Replication Adapter is a software add-on that integrates with VMware vCenter Site Recovery Manager (SRM) solution. It enables SRM to perform failovers together with IBM DS8000 storage systems.
This release brings the following new features:
In addition, version 2.3.1 introduces support of the all-new member of the DS8000 family, DS8880 (v.8.0), enhancing its industry-leading disaster recovery capabilities.
We are proud to announce that the IBM Storage Driver for OpenStack has been recently upgraded to a new version - 1.6.0. This version brings support for OpenStack Liberty release, as well as for DS8870 microcode version 7.5 SP3 and DS8880 version 8.01. In addition, this release introduces the XIV and Spectrum Accelerate support for the OpenStack consistency groups. It also brings in the RESTful API that replaced the Java-based ESSNI driver in DS8000 storage systems.
IBM Storage Support for Microsoft Volume Shadow Copy Service and Virtual Disk Service, version 4.11.0.
A new version of IBM Storage Support for Microsoft Volume Shadow Copy Service and Virtual Disk Service has been released. This is version 4.11.0, which introduces support for the following storage system microcodes:
Also, version 4.11.0 adds support for temporary (non-persistent) read/write access to a snapshot.
IBM Spectrum Control Base Edition has been upgraded to a new version - 2.2.1. This release replaces the previous version (2.2.0). It introduces support for the VMware virtual volume (VVols) and Storage Policy Based Management (SPBM) technologies for the storage systems that run the IBM Spectrum Virtualize software with microcode version 7.6.0. These are:
Additional changes include support for new data encryption method used by the Spectrum Virtualize software and ability for a storage resource attached to a VVol-enabled service to use other storage resources for VVol snapshots if it has reached its capacity.
We are happy to announce the release of an updated OpenStack Cinder driver for IBM Spectrum Virtualize, Storwize Family and FlashSystem V9000. This release complies with OpenStack Liberty specifications, emphasizing IBM's continuous commitment to making the cutting-edge OpenStack features available for IBM storage customers.
Another change is the enabling or disabling the fast format option during thick volume creation. As some volume operations are disabled until fast format is completed, the customer can now skip the fast format, when creating a thick volume. This makes the volume operational immediately after its creation.
Version 7.6 of IBM Spectrum Virtualize and Storwize Family will be supported after its release with no additional Cinder driver code change.
We are proud to announce that the IBM XIV Host Attachment Kit has been recently upgraded to a new version - 2.5.0. This release brings support for XIV microcode version 11.6.x, IBM Spectrum Accelerate 11.5.1.x, and RHEL 7.1. In addition, this version introduces a hot feature - the host-side acceleration (HSA) for improved iSCSI communication between Spectrum Accelerate and a host.
Another change is a deprecation of the -L option of the xiv_iscsi_admin and xiv_fc_admin commands, reserving the ability to list the attached storage devices for the xiv_syslist -L command only.
IBM Spectrum Control Base Edition continues its evolution with a new version - 2.2.0. This release brings support for VMware VASA 2.0 without virtual volumes for DS8870 7.5.x (using patch DS8870_REST_API_7.7.51.xx.zip) and adds support for IBM Spectrum Accelerate version 11.5.1.x.
Additional changes include ability to manage storage resources directly from the pool list per storage system or storage service, using the Spectrum Control Base GUI. Also, starting from version 2.2.0, DS8870 storage systems make use of the RESTful API client to simplify the Spectrum Control upgrade and installation procedures, eliminating the need for previously used JRE extension bin files.
In general, IBM Spectrum Control Base Edition became a more robust, use-friendly and fault-tolerant solution for managing multiple IBM storage platforms.

It's been a long 9 months since the release of the IBM XIV HAK 2.2.0 and we're back with a new exciting release - IBM XIV HAK 2.3.0 .
Example 1: Cleaning up a stale device
The next feature is also a response to customers needs. People using Veritas Dynamic Multi-Pathing (DMP) had issues running xiv_attach, as it always configured and initiated the native multipath framework. Two multipath frameworks on the same host is like having two managers not speaking to each other, each pulling in another direction.
Example 2: xiv_attach in presence of Veritas DMP
A third feature relates to the new release of XIV Microcode 11.5 and a feature we call Multi-Tenancy. Let's say you have two companies working on the same storage, each with it's own data that should never ever get to the other company. The storage can be divided into domains so that each is maintained by separate people, unaware of each others work. From the point of view of the storage administrator running xiv_attach or xiv_iscsi/fc_admin, he just uses his credentials to connect to the storage and everything behaves as expected. In case a user is able to see more than one domain (e.g. in case of domain per department) he is able to specify the domain the host should be using via a flag in the xiv_iscsi/fc_admin command line.

We've just released the IBM Storage Driver for OpenStack v.1.3.0, get it
now while it's hot from the oven!
IBM Storage Driver for OpenStack v1.3.0 package now includes:
* OpenStack Havana Support (Including Volume migration)
* IBM DS8000 Storage System in addition to the IBM XIV Storage System
* In addition to Ubuntu 12.04 x64, we now also support RHEL 6.4 x64
* The driver package now includes a script for creating OpenStack Cinder Volume types. Read about Openstack Cinder volume types here.
Lets look at an example of the Volume types script we mentioned:
Assuming you have the following two backends configured in your cinder.conf file:
You can now run the 'create_volume_types.sh' script, to automatically create volume types to point to these backends.
After running this script, you can see your automatically created Volume types by running:
This is it!, your volume types are set and you can now use them when creating volumes:
#cinder create --volume-type IBM-XIV_hostdev31f.xiv.ibm.com_vwc_iscsi --display-name vol_hostdev31f 5

It's been 4 months since the release of the IBM XIV HAK 2.1.0 and we're back with a new release - IBM XIV HAK 2.2.0.
So what's new in this release? We won't bother you with all the changes and fixes - you can find the detailed list in the Release Notes document coupled with the software package. We would however like to point out that the new release supports a new operating system - Microsoft Windows Server 2012 R2 - an important step by itself. But the main feature of this release is related to xiv_host_profiler and the way 'analyze' operates.
Since the addition of xiv_host_profiler utility in the HAK 2.0.0 release, we see growing interest in this application. Administrators want to know that the system they are working on is configured right and how to improve their settings. Makes sense, doesn't it?
The problem was that the analysis was based on the latest microcode released, and this is not the common situation in the field. Following the famous "if it ain't broken don't fix it" approach, upgrading the storage microcode is not done as frequent as we'd like it to happen. So for example, although a microcode version 11.1.x is used, the administrator would get the analysis results of 11.2.0 (HAK 2.0.0) or 11.3.0 (HAK 2.1.0) which have different rules.
To solve this problem in the new HAK release we collect the microcode versions of the connected XIV storage and the analysis is based on these versions. So if your host is connected to 10.2.4 or to 11.2.0 or 11.3.0, you can expect different results. In the following example you can see the same host running against two different microcode versions with two different analysis results.
And what about testing your configuration against a different microcode version? For example, if you have an XIV system running microcode 11.2.0 and you want to upgrade to 11.4.0 - will your host configurations still be valid? So we added an option for the user to specify the microcode version he is interested in.

If you happen to be using one or more IBM storage systems that are serving your VMware environment, we invite you to check out our recently released ’IBM Storage Integration Server’, a software solution that consolidates all your IBM storage usage through a single backend deployment.
You can add your IBM storage arrays into the scope of IBM Storage Integration Server in just one step, by using your storage user credentials as shown in the following example from the web-based management interface:
Once added, the arrays would be available to all supported solutions, without having to re-add each storage array separately for each solution or for any future supported solution.
This single integration server reduces the amount of management traffic and shares the queried storage information with all the supported solutions. The first release, version 1.1.0, introduces support for ‘IBM Storage Enhancements for VMware vSphere Web Client’ and for ‘IBM Storage Provider for VMware VASA’.
‘IBM Storage Enhancements for vSphere Web Client’ enables native visibility and provisioning of IBM storage volumes (LUNs) within VMware vSphere Web Client. These enhancements bring the value of the already known and acclaimed IBM Storage vCenter plug-in, formally known as ‘IBM Storage Management Console for VMware vCenter’, to the new web-based VMware vSphere Web Client, which allows the integration of multiple vCenter servers instead of one.
VMware administrators who were previously daunted by the thought of the complex task of connecting and utilizing storage resources through vSphere Web Client – can now be much more relaxed with the ability to easily create and manage storage volumes in delegated storage pools, which were attached by the storage administrators on the IBM Storage Integration Server side.
‘IBM Storage Provider for VMware VASA’, previously a standalone plug-in, is now a feature of the IBM Storage Integration Server, adding the following enhancements:
· Supports the IBM Storwize family in addition to the existing IBM XIV support.
· Storage capabilities are automatically defined and assigned, eliminating the need for manual definition and assignment.
That’s about it, for now J
More to come soon!

It's raining new releases here at IBM HSG, the latest software released from our team is the IBM XIV HAK v2.1.0.
The HAK is already a well known, widely used toolkit, therefore in this post we will focus on what's new in this latest release, and what will you gain by installing or upgrading to this version.
The first feature to note is the added support for version 11.3.0 of XIV microcode and more importantly for the Online Volume Migration (OLVM) feature. Now the "good old" xiv_devlist utility also presents the OLVM state of each and every volume exposed to the server, providing the host and storage administrators an easily accessible tool to stay updated with the migration state of the volumes under their responsibility, without the need to access the XIV Management GUI.
In addition, the recently introduced host diagnostic utility, the XIV Host Profiler , can now be defined as a scheduled task right from the Host Attachment Kit Wizard - xiv_attach. No need to remember to set it separately, the user will be asked during host configuration if a task should be scheduled to run the utility periodically.
We've also improved the xiv_devlist and xiv_syslist commands' CSV file format output utilities. From this release, by adding the --no-headers argument, the column headers will be omitted from the generated CSV file.
On top of the above-mentioned features and enhancements several stability issues were also fixed. The detailed list of those issues can be found in the Release Notes document coupled with the software package.

We have just released the IBM Storage Driver for OpenStack v1.2.0 and would like to share some of the more important features in this release.
The IBM Storage Driver for OpenStack is a software component that integrates with the OpenStack cloud environment and enables utilization of storage resources provided by the IBM XIV Storage System.
So what's new in our latest release?
Support for the OpenStack Grizzly release, which adds support for multiple storage backends on a single Cinder node. During the installation of the IBM Storage Driver for OpenStack v.1.2.0 on the Cinder node, the installation wizard will enable the configuration of multiple XIV storage backends, may it be two or more separate XIV systems or storage pools on the same XIV system.
Our Storage Driver now supports Fibre Channel (FC) storage connectivity to the compute node, in addition to the already supported iSCSI protocol.
To ease the installation and setup process of the new IBM Storage driver, we have enhanced the unattended installation of the IBM Storage Driver for Open Stack with the option to use a pre-configured ini file which includes the parameters of all the storage backends to be configured during the installation process.
In addition we introduced several fixes and code stability improvements.

A few days ago we have a released a new version of our VASA Provider for the XIV Storage System.
For those unfamiliar with VMware VASA or with the previous version of IBM Storage Provider for VMware VASA , here is some background:
VASA stands for vStorage API for Storage Awareness, and it is an API specified by VMware and implemented by storage vendors to standardize communication between the various storage systems and the vCenter Server. The Storage Provider is a web server that handles requests from the vCenter Server in which it is registered.
The IBM Storage Provider provides a standard interface for any connected VMware vCenter Server using VMware APIs for Storage Awareness (VASA), delivering information about XIV storage topology, capabilities and state, as well as storage events and alerts to vCenter Server in real time. VMware administrators can view this information on the vSphere Client management station, and can configure storage-related operations accordingly
For example an IBM VASA Provider registered in a VMware vCenter will provide the following information in the "Storage View" tab of the vShpere Client (both web and c#)
Screenshot from vShpere Client 5.1
In version 1.1.5 several major enhancements and changes were introduced:

In this information center, or IC, you can find the relevant documentation of all the solutions that we offer, including information of both past versions and the latest versions.
Whether our host software solution is for XIV, DS8000, Storwize, or any other IBM storage system – the release notes, user guide, or installation guide are available on the IC in either PDF or HTML format (whatever suits you best).
The solutions are categorized on the navigation tree under four main categories: business continuity, management, host connectivity, and virtualization. Keep in mind, however, that some solutions could belong in more than one category. For example, a solution such as IBM Storage Management Console for VMware vCenter is placed under the virtualization category, but it may also be regarded as a powerful management solution. For another example, our XIV and SVC adapters for VMware vCenter Site Recovery Manager, also placed under virtualization, may also be regarded as business continuity solutions.
In any case, we hope that the organization of our solutions on the IC makes sense to you, and that the information is helpful. If not, please let us know! You can use the online feedback form that is available on the IC.
Each solution has its own welcome page from which you can have quick access to the information of the available versions. The PDF publications are available on the Publications page of each solution.
If you'd like to see our list of solutions per independent software vendor (ISV), check out the Solutions by ISV page. Alternatively, to see which solutions are available for a specific IBM storage system, check out the Solutions by storage system page.
And, of course, the IC is regularly being updated and improved. You can always check what's new on the IC by visiting the What's new page.
Lastly, we would like to thank our Information Development team for making it happen.

The new version adds the following enhancements for XIV users:
From now on, for each new volume you create on the storage system, the IBM storage plug-in enforces the chosen MP policy. Alternatively, if you choose Disable Multipath Policy Enforcement, no MP policy is enforced (in such a case, VMware’s default MP policy for the storage array will be in effect).
These enhancements also apply to other IBM storage systems that the plug-in supports. In addition, version 3.0.0 introduces support for IBM Storwize V7000 Unified and IBM Scale Out Network Attached Storage (SONAS) as well as various bug fixes. You can check out the release notes for more details.
After you’ve heard all that, you can now go ahead and download the IBM Storage Management Console for VMware vCenter version 3.0.0 along with its documentation from the IBM Fix Central.
We’d love to hear your thoughts and comments, so please share them with us!
We are excited to announce release of IBM XIV SRA 2.1.0 that is compatible with VMware Site Recovery Manager 5.0.
About SRM 5.0:
Site Recovery Manager 5.0 includes three major additions to the workflow capabilities:
About IBM XIV SRA 2.1.0 with VMware SRM 5.0:
The IBM XIV SRA extends SRM capabilities and allows it to seamlessly employ XIV replication and mirroring as part of the SRM comprehensive Disaster Recovery Planning (DRP) solution.
Using the IBM XIV SRA, VMware administrators can automate the failover of an XIV system at the primary SRM site to an XIV system at a recovery (secondary) SRM site. Immediately upon a failover, the ESX/ESXi servers at the secondary SRM site start using the replicated datastores on the mirrored volumes of the secondary XIV system.
That's great ! But where can I get It ?
It's already available at the VMware download page of SRM 5.0.1 (You can click on the "Show Details" link inside the "Components" section to reveal the list of SRA components with IBM XIV SRA included)
We would love to hear from you, please leave you questions and comments below.
