Incrementally restore a subset of SGC volumes

PH44217 introduced incremental restore capability to Production but is currently an "all or none" approach. We believe there may be scenarios where specific volumes or applications might be affected by corruption and so we would like to have a sim...

FTDC for GDPS/LCP SGC Capture failures - ODDs to disk

GDPS/PPRC has not been reliably taking ODDs in all GDPS/LCP SGC capture failures that we've seen. As a result, IBM DASD microcode has not been able to determine why several of our SGC captures have failed. This idea is to enhance GDPS/LCP first ti...

Setting IPLType on KG-Syestem versus setting on the (LCP) R-system should be same

In an LCP setup it is possible to set the IPLTYPE both on the KG-System as on the (LCP) R-System. When setting it on the KG-System it is also propagated to the R-system. The other way around this is not the case. So when setting the IPLTYPE on the...

Dual control function for DASD Config

Within the DS8K there is protection in place that a (malicious) person is not able to delete/alter devices that are part of safeguarded copies. We have a cybervault LCP setup to ensure we have immutable backups of our systems, and activated Dual C...

Automatic increase virtual capacity for volume Safe Guarded Copy

When a SG backup volume runs out of Virtual Capacity, have the DS8K automatically increase the Virtual Capacity Multiplier with 1 for that volume. The increase by 1 should be sufficient I think, I do not think this should be configurable. However,...

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...
