Hi guys, we have a surprise for you!
We have just released a Python library for our XCLI client. It's an open-source project and free for use by everyone under the Apache 2 license. It enables connecting to the storage and managing all its operations. It supports all XCLI managed storage types:
This is the first open-source version of the Python XCLI client library ever. This may not sound like such a big deal, but it actually is. It enables users to tailor the way they use the Spectrum Accelerate Family storage.
The XIV GUI is great, and so is the new IBM Hyper-Scale Manager and they let users to do almost anything with the storage. But there are cases that you would rather have specific functionality that is suitable just for you. The flexibility and power of Python and XCLI enables you to tailor it to your exact needs.
Let's take two simple examples:
1. You want to take snapshots for the production volumes in pool FOO every day. Just create a scheduled task and run the following script:
from pyxcli.client import XCLIClient
xcli = XCLIClient.connect_ssl('admin', 'adminadmin', 'mystorage.comp.com')
volumes = xcli.cmd.vol_list(pool='FOO).as_list
for volume in volumes:
2. You'd like to clean up your system and remove all empty volumes. Here is how you create a list of unused volumes:
from pyxcli.client import XCLIClient
xcli = XCLIClient.connect_ssl('admin', 'adminadmin', 'mystorage.comp.com')
volumes = [volume for volume in xcli.cmd.vol_list().as_list if volume.used_capacity == '0']
for volume in volumes:
The combined power of Python and XCLI management has been unleashed!
You are welcome to use it!
Download the package from:
- GitHub: https://github.com/IBM/pyxcli
or simply run 'pip install pyxcli' from your command prompt.

You may ask: version 3.2.0 is already available so soon? Our answer: yes. Although earlier this month we released IBM Spectrum Control Base Edition version 3.1.1, version 3.2.0 is a genuine breakthrough, bringing support for the Microsoft PowerShell automation tool, in addition to our already well-established VMware cloud integration offerings. The new IBM Storage Automation Plug-in for PowerShell provides 'cmdlets' for automated storage management, including provisioning, host mapping, volume expansion, and other storage-related tasks.
For the first time, you can download the plug-in from the Microsoft PowerShell Gallery website at: https://www.powershellgallery.com/packages/SpectrumControlBase-Client. For further details about this new version, including fixes and an experimental Flocker feature (might not be included in future versions), check out the IBM Spectrum Control Base Edition 3.2.0 release notes on IBM Knowledge Center at: https://ibm.biz/Bds7gK.

We are happy to announce that we have released several drivers to support the new version of the OpenStack Cinder project: Ocata. This, however, is not an ordinary release, and here's why: previously, the drivers for IBM SAN Volume Controller, IBM Storwize Family, and IBM FlashSystem V9000 storage systems were the only ones included in the OpenStack community source code. Now, this latest release is a huge step forward aimed to include IBM FlashSystem A9000 and A9000R, IBM XIV, IBM Spectrum Accelerate (deployable software), and IBM DS8000 Family systems in the community source code as well, moving from proprietary code to being fully open-source. So henceforth, the IBM Storage Driver for OpenStack is part of the OpenStack Cinder repository. Accordingly, the driver documentation has also migrated from IBM Knowledge Center to the OpenStack community website: https://docs.openstack.org/ocata/config-reference/block-storage/drivers/ibm-storage-volume-driver.html
This release was developed in accordance with the OpenStack Ocata specifications, emphasizing our continuous commitment for providing IBM storage customers with cutting-edge OpenStack capabilities. In addition to the aforementioned integration in the community source code, this driver version includes enhancements in replication functionality (also known as "cheesecake") of the supported IBM systems, as well as improvements in multipath support, and auto-selection of I/O groups for Storwize storage systems.
As always, we are here to help with deployment and operation of our OpenStack drivers. Your feedback is important to us, and we'll be happy if you let us know what you think about this milestone release.
The IBM Flash Centers of Competency has posted a very good blog about our latest SCB version

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 are glad to announce the release of Spectrum Control Base Edition (SCBE) 3.1.
This new version introduces the following improvements:
Spectrum Control Base Edition 3.1 can be downloaded from Fix Central:
We'd be glad to hear your feedback!
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.
