about 3 years ago in GDPS 21 Not under consideration

In a GDPS MGM TOPOLOGY the KG/KR analyzes if the tertiary disks are ONLINE by any system, before accepting the GDASD START SECONDARY RESTART command.

After a recovery simulation test on the B.RS1 disks (tertiary disk in Region B), we had problems in the synchronization process of the GM copy (GDASD START SECONDARY RESTART command) when having some disks ONLINE from an emergency system (it was u...

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...

about 2 years ago in GDPS 1 Is a defect

Issue a GEOxxxxxI message every time an LCP SGC capture expires, including a creation timestamp in the message information

This would allow customers relying on LCP for cyber security to monitor the expiration of capture to ensure that no captures were being expired outside of agreed time limits.
