Provide a DELETE option for the STOP SECONDARY, and a NOCOPY option for the START SECONDARY script statements

As an MGM4SITE environment with external LCP, we have regular resiliency tests where we failover from one region to the other (REG-A to REG-B). When we do this we have to terminate the copy to the LCP source disk in the old recovery region (REG-B)...

Exclusively run the Hyperswap 'Phase 1 check', via a Planned/unplanned Hyperswap script.

We would be interested in having a tool (SCRIPT,...) that could be executed before running a Planned/Unplanned HS simulation, and certify whether we are (or not) prepared to be able to perform an HS without causing, for example, the fall of a syst...

Health check for zIIP processors on KSYS

It is recommended that reserved zIIP are available in a KSYS and it would be very helpful to have a new Health Check raising a warning if a KSYS LPAR has available zIIP but they are not reserved. This Health Check should be customizable for differ...

Let the GDPS automatically perform the 'FCWITHDRAW FC1' if it detects that the extended groups are filling up.

We currently have an GDPS MGM3SITE configuration and are thinking about defining FC1 disks to be able to perform 'recovery tests in Region B' without affecting the GM copy. FC1 disks are ESE. In testing of filling Extend Pools in TEST environments...

GDPS should automatically clean up from destructive repair operations on storage devices

We recently had a "B" box outage that required support to utilize the CST process that removes all in memory structures including copy services. This created orphaned secondary pairs in our GDPS Metro Global session. Currently within GDPS we can o...
