On November 15, 2016 IBM announced the next version of IBM Copy Services Manager, version 6.1.4
IBM Copy Services Manager is a storage replication product that provides a single place to manage all the replication across your IBM storage environment. With IBM Copy Services Manager customers can simplify the management of their replication solutions while providing disaster recovery and high availability to their applications.
What's New in IBM Copy Services Manager 6.1.4?
We're very excited to provide the following key features being released in this new version.
Support for Extent Space Efficient (ESE) to standard volume Peer-to-Peer Copy (PPRC)
The DS8000 has announced support for remote replication from an Extent Space Efficient (ESE) volume to a standard volume and vice versa. In Copy Services Manager 6.1.4 we have added support for this configuration. When you create a session and add copy sets to that session, the session will now allow you to select Extent Space Efficient volumes for any role in DS8000 supported sessions.
Support for IBM FlashSystem A9000 and A9000R
IBM Flash Storage is the Future. IBM
Support for Ubuntu Linux distributions
IBM Copy Services Manager has supported Red Hat Enterprise as well as SUSE Linux installations for quite awhile now. However, as Ubuntu has matured, more businesses have started to move to it for enterprise Linux. With Copy Services Manager 6.1.4, customers can now install the product on a Ubuntu 15.04 LTS server or higher. We are happy to be able to now support Ubuntu and continue to meet the changing needs for enterprise customers.
DSCLI for z/OS installations included with Copy Services Manager for z/OS
IBM DS8000 storage and z/OS have go hand in hand and meet customer enterprise needs. When managing DS8000 for mainframe environments automation can play a huge roll. Customers desired the ability to setup batch jobs on z/OS that could invoke DSCLI commands in order to manage the hardware. This could be manually setup if necessary but there has never been an official installer to install the DSCLI on a z/OS system. Now, with the purchase of the IBM Copy Services Manager 6.1.4 Basic or Full license, customers have access to an official z/OS installation for the DS8000 DSCLI. To access this customers that have purchased the Copy Services Manager Basic of Full license can go to shopZ and search for FMID HIWN61K.
Ability to setup SNMP and email notifications through the Copy Services Manager GUI
ALWAYS stay in the know! With the 6.1.2 release we added in the ability to setup email notifications for Copy Services Manager related events, however, you could only set that up using the CSMCLI. With Copy Services Manager 6.1.4, you can now setup and manage alert notifications from the GUI as well. From the main navigator select Settings->Alert Notifications and you can manage either email notifications or SNMP notifications. For email notifications, define your email server and the list of email addresses you wish to be notified of Copy Services Manager events. For SNMP notifications, specify the SNMP listener that the Copy Services Manager should send SNMP events to. It's that EASY!
Single direction support in port pairing CSV file
Copy Services Manager has supported a CSV file for port pairing definitions in order to help a customer manage their PPRC paths easier. The file defined which port pairs to use for various supported configurations. The file however assumed that all port pairs were bi-directional, meaning that the customer would want the same port pairs if going from site 1 to site 2 as they would going from site 2 to site 1. This however, is not always the case. Sometimes customers want to use a different set of port pairs when replicating data in the opposite direction. In addition, some third party vendors do not support bi-directional pathing. Because of this, Copy Services Manager 6.1.4 has updated the support in the port pairing file to allow a customer to define port pairings based on a single direction.
The entry for the port pairs are bi-directional unless the last comma separated entry on the line is the string "onedir". This means that a line that has systemA:systemB is equivalent to a line that has systemB:systemA and the last entry in the file will take precedence.
New events for SVC auto restart solution
One of the new features that Copy Services Manager offers over the previous Tivoli Productivity Center for Replication product, is the ability to auto-restart a session if a suspend 1720/1920 error occurs. There are however, certain conditions where the restart might not occur. For example, in order to protect the customer from an endless cycle of suspend and restarts which could end up impacting production i/o, Copy Services Manager will track the number of restarts and then fail to do the restart if we've attempted too many restarts in a specified amount of time. While the Copy Services Manager server sends out an alert on the state of a session when it goes to a Suspended state, as well as when a auto restart causes the session to go to a Preparing/Prepared state, there were no events that indicated if an auto restart failed to occur. There are customers however, that have automation in place that needs to know if a ticket should be opened to have someone take a closer look at the issue. With Copy Services Manager 6.1.4 we have added not only an event indicating that an auto restart has occurred, but also an event indicating if an auto restart failed to occur. This event is supported for both SNMP as well as email notifications.
IWNR1961I [Aug 9, 2016 1:52:33 PM] A suspend event occurred triggering the auto restart feature for session session_name. The session will be restarted in delay_time seconds.
IWNR1962E [Aug 9, 2016 1:52:39 PM] Session session_name was enabled for auto restart however a failure occurred attempting to restart the session.
FlashCopy Manager for z/OS (delivered in Copy Services Manager 6.1.3)
On August 5, 2016 Copy Services Manager 6.1.3 GA'd. With this release the CSM for z/OS solution released the CSM FlashCopy Manager for z/OS solution. This solution was designed to provide greater ease of use and to provide faster integration of IBM DS8000 FlashCopy into System z production batch environments. It was also designed to provide significant System z FlashCopy performance enhancements. Using any existing JOB scheduler, customers can exploit IBM Copy Services into the existing z/OS or System z batch environment.
Some of the functions include:
Customers that have purchased the Copy Services Manager Basic or Full license can access the solution from shopZseries using FMID HIWN61F.
Display and Export Pokeable information for DS8000 (delivered in Copy Services Manager 6.1.3 with DS8000 8.1.1 or later)
Customers working with copy services and a DS8000 system may be told at times to modify certain tuning values on the storage system known as pokeables. These settings may not be kept across actions such as microcode upgrades, however there was no easy way for the customer to view what the current settings were. With IBM Copy Services Manager 6.1.3, a customer can now view and export the current pokeable settings for the storage system. While on the Storage Systems panel, select a storage system and then from the actions drop down you can select View Advanced Settings for the storage system. The View Advanced Settings option will only appear on DS8000 8.1.1 systems or higher. This will bring up a dialog that shows you all values that are something other than the default as well as provide a mechanism for you to export the current settings to a CSV file. These settings cannot not be modified through the Copy Services Manager interface and should only be modified based off of direct feedback from IBM support.
Additional Information about IBM Copy Services Manager 6.1.4
Copy Services Manager on the DS8000 HMC does not currently support z/OS Host connections for HyperSwap management
A Copy Services Manager server has the ability to specify the IP/hostname and credentials for a z/OS System and connect to it via IP for the purposes of managing the z/OS HyperSwap or Hardened Freeze features from a remote server. However, while this IP connection currently requires a secure connection to the hardware via SSL/TLS. SSL/TLS connections require a certificate be loaded on the Copy Services Manager server so that the connection to the z/OS System can be authenticated. The DS8000 HMC is a locked down system that does not allow a customer the ability to access the file system and thus there is currently no way to support z/OS connections from a Copy Services Manager server running on the HMC. We are looking at ways to add this as an officially supported solution in a future release of Copy Services Manager.
When running Copy Services Manager on the DS8000 HMC the following features are supported without a license
Setting up a Copy Services Manager to z/OS Host Connection without a secure connection
Setting up a Copy Services Manager connection to a z/OS Host via an IP connection currently requires a secure connection. This means that security must be setup properly on the z/OS side and a certificate needs to be created so that all commands that are sent between the z/OS System and the Copy Services Manager server are encrypted. Setting up security properly on the z/OS side can be quite challenging depending on the environment, though we have attempted to document this and are currently working on updates to the RedBook. If however a POC needs to be executed quickly and a secure connection cannot be setup, it is possible to setup the connection without SSL/TLS. Before doing this a customer needs to be aware that all communication will not be encrypted.
To remote the requirement for an SSL/TLS connection do the following:
