Simplify the process of extracting volumes in MGM copy.

Good Morning,


In environments where GEOPARM is complex, managing extraction of multiple volumes of the MGM copy is complex. The process is very manual (you have to go through GDPS panels to RESUME the disks, then FW the FCs, then delete the GM/GC copy of the disks... all by panels) and in the case of being a high volume of devices, it is very entertaining.
Furthermore, once we propagate these changes to the MM part (KP-systems), it is necessary to perform a Full Erase of the IR at the level of the entire GEOPARM and an activation of the IR at the level of the entire GEOPARM. Every time an action is performed on the Incremental Resync it is necessary to perform a 'FREEZE/RESYNC' of the MM copy, endangering the integrity of the copy in Region A during the process (fortunately it is usually very fast)


Thanks
Regards, Miguel.

    Would be very useful to Itau since we have a 2 large sysplex to deal.

    For adding and especially removing devices we now have a multiple (conditional) step procedures which have to be executed manually (is higher risk).

    Where you would rather want to update the GEOPARM, do a test activation (get info on what steps will be taken) and have GDPS perform the needed actions.

    Will ease the management, definitely useful for us, too.

    I have raised a similar idea not under consideration - ZGDPS-I-174 - resizing volumes as mentioned here moving from full to thin provisioned is a very cumbersome task. The DS8k offers dynamic volume expansion, I think that should be available from the GDPS side as well to manage the mirroring relationships during the dynamic volume expansion.

    Converting a volume from full provisioned to thin provisioned in a 3-site MGM environment is very complex. Volume needs to be removed from and re-added to GDPS, which can be an extremely time consuming and prone to error procedure. This area needs major improvement.
