On November 17, 2017 IBM GA'd the next version of IBM Copy Services Manager, version 6.2.1
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 6.2.1
As always, we're very excited to provide the following key features being released in this new version. We develop Copy Services Manager in an agile development cycle and as such have included a number of customer requested features!!!
Usability enhancements to the CSM GUI Session Overview Panel
The 6.2.1 version of Copy Services Manager now provides the ability to hide or unhide columns on the session overview panel. The session overview panel holds a lot of key high level information for each session. But it's possible that in your environment you might not care about all the values. For example, in a Distributed environment you may not need the HyperSwap column indicated whether z/OS HyperSwap is enabled on a session. With this release, you can now choose to hide those columns which you don't use. Simply right-click on the table header or click on the icon in the right most corner of the table header and uncheck any columns you don't want to see. What if you decide that you want to see the column after all? Simply recheck that column and it will reappear in the table.
Are you tired of making changes to the Session Overview panel table, such as sorting, filtering, column resizing or repositioning, and then having to make that same change every time you log in? In Copy Services Manager 6.2.1, all of the table customizations are now saved for each user every time they log into that same browser, thus increasing their productivity and the usability of the product.
Support for restoring IBM Spectrum Virtualize FlashCopy Sessions
In Copy Services Manager 6.2.0, we introduced the ability to restore a DS8000 FlashCopy session. This allows a customer to restore a volume back to the time of the last Flash on the session. In Copy Services Manager 6.2.1, we added the feature to all IBM Spectrum Virtualize based FlashCopy sessions as well. The provides greater usability across the entire IBM Storage portfolio.
Support to create DS8000 system diagnostics from the CSM GUI or CLI
When managing copy services with Copy Services Manager there are times when hardware errors may occur and support may need to be called. In the 6.2.1 release we've made it even easier to collect the data support needs to help the customer provide a faster time to a resolution. Not only can you collect the CSM log package but now from the Storage Systems panel you can click on a DS8000 Storage System and from the action menu select Create System Diagnostics. This will provide a prompt allowing a customer to issue an On Demand Dump (ODD) or a Warmstart of the DS8000 system, without having to login to the DS8000 GUI or CLI. From the CSM CLI, the mkdevicedump command can also be used in case the GUI cannot be accessed or to issue via a script.
Change to copy and clean rate on IBM Spectrum Virtualize FlashCopy sessions
IBM Spectrum Virtualize FlashCopy sessions changed the maximum clean and copy rate for FlashCopy relationships and consistency groups to 150 in their 7.8.1 release. Copy Services Manager 6.2.1 now let's you take advantage of this update. In the GUI you can set the copy rate from 0 to 150, and in the rmserver.properties you can now specify the clean rate using the prop
New Global Mirror Either Direction session without Practice
Copy Services Manager has had support for DS8000 Global Mirror for a long time, with solutions ranging from regular Global Mirror, to Global Mirror with Practice, to three site solutions with Global Mirror. In the 6.2.1 release, Copy Services Manager is providing yet another Global Mirror solution. This new session type allows customers to create a session that can Global Mirror from site 1 to site 2 or site 2 to site 1 in an asynchronous and consistent mode, without having practice volumes. This is a key solution in environments where customer want the ability to failover and run for an extended period on their remote site, and have disaster recovery protection while they do so. It is also a key solution for environments like iSeries where Global Mirror is uesd but do not require the need for practice volumes.
New space-management methods on Global Mirror sessions
Customers can use space efficient volumes for the journal volumes in a Copy Services Manager Global Mirror session, in order to save costs. There are cases however where the backend space may fill up for the space efficient volume. Copy Services Manager 6.2.1 makes it easier for customers to decide how they want to manage their session when space efficient volumes are used. Across all the Global Mirror session types, customers can now uncheck the "Reflash after Recover" option on the session properties. This tells the session that after executing the recover, it should not reflash to the journal volume. If customers know they may need to save backend space after the recover this option can help prevent errors before they occur.
In addition, a new command "Free Journal Space" has been introduced. When the session is in a Suspended or Target Available state, a customer can issue the Free Journal Space command to have CSM terminate the journal FC relationships. This can help free up the journal volumes so that the resynchronization of the Global Copy relationships in a Global Mirror session will not lead to an out of space condition.
Support for scheduling actions against FlashCopy sessions
One of the most requested features in Copy Services Manager, is for it to have the ability to schedule commands against a session. Today commands can be scheduled using an external chron job running against the Copy Services Manager CLI. But with the 6.2.1 release, a new internal scheduler has been added. The scheduler is limited to only the Flash command against sessions that support a Flash command, but this lays the foundation for more complex scheduling capabilities in the future. Schedule a Flash to occur on a hourly or a daily/weekly schedule. And get SNMP/email notifications in the event that a scheduled Flash fails.
Path SNMP/email alerts for any detected path failures
Copy Services Manager provides an SNMP/email alert today in the case that all paths are lost between two DS8000 LSSs. With 6.2.1 a new event was added to indicate the loss of ANY path between DS8000 LSSs. It's important for customers to know when even a single path has been lost as this could lead to performance degradations. Copy Services Manager can help provide notification thus enabling the customer to remedy the issue before it leads to even more issues.
Automatically restart Multi-Target sessions at remote site after HyperSwap
Multi-Target session in Copy Services Manager for DS8000, allow customers to easily and quickly transition between sites. And when z/OS HyperSwap is enabled on a Metro Mirror leg of a Multi-Target session, customers can add in high availability to their environment. However, today when either a planned or unplanned swap occurs, while production will continue on the secondary storage system, all replication must be manually restarted. With 6.2.1, a new property can be added to the rmserver.properties file that will tell the session to automatically start the session from the secondary after the swap is complete, against the remote leg of the session. This not only helps to provide continual disaster recovery protection but in a MT MM-MM session can help keep a customer highly available even after swapping.
Support to convert zip file key to String key for CSM on the DS8000 HMC enablement
In order to enable Copy Services Manager on a DS8000 HMC, a String key is required. Some ordering systems however only provide a file based key and not the String key. To get the String key customers have to install a full image of Copy Services Manager and then export the key from the Advanced Tools Panel. With this release a customer, now launch the Copy Services Manager installer in a special mode, that will allow a customer to input the file based key and convert that to a String based key, without having to install the full Copy Services Manager server.
Ability to modify the rmserver.properties from the CSM GUI
The Copy Services Manager has several properties that can be set in the rmserver.properties file which are not available on the GUI or CLI. However there are instances, like when Copy Services Manager is running on a DS8000 HMC, that a customer may not have access to the file system in order to modify the rmserver.properties file. In a previous release the chsystem command was introduced on the CLI to allow a remote setting of the options. However, while this allowed customers to change the value, it didn't allow them to see and validate that they set the property correctly. With 6.2.1, you can now view and edit the rmserver.properties directly from the Copy Services Manager GUI. Click on Settings->Server Properties in the Navigator and your free to now make changes without requiring access to the file system.
