No support of TR31 Block D K1 keys with dual mode of use

ICSF does not support TR31 K1 keys of type D with mode of use B(for encrypt and decrypt). CSNBT31I service ends with cc8/rsn7e0 (incorrect rule array parameter content). This makes ICSF CCA incompatible with authorities that do not separate KEKs a...

STP setting and customization

With customers moving to zCloud, we are now combining customers with z/VM lpars set in different timezones onto a single processor. There needs to be a better method of utilizing STP, to alleviate unnecessary manual updates to the System Config fi...

Additional subchannel sets

With the implementation of GDPS 4 Site, we have drastically depleted UCB's in our KPAR's and SDMPLEX, we are requesting at least 6 MSSes per LCSS in support of 4 Site and future UCB growth. We have worked for years on UCB reclamation to comply wit...

Add <refresh> option in Manage PCI System Services panel

The Manage PCI System Services panel doesn't have a refresh option, so when we configure the CHP of/on to z/OS, the status is not updated, we need to cancel out of the panel and go back in. It would save time if a <refresh> option were provi...

Provide clickable fields on the System Information Query Additional Actions panel

On the System Information Query Additional Actions panel, there are several different panels/tasks referenced. It would be helpful if these were hyperlinks, so the user could just click on those links instead of clicking on <OK>, then locati...

Crypto Hardware Adjunct Processor Assignment

Crypto Adjunct Processors (APs) are assigned to Crypto PCHIDs at Power-on Reset time. In our experience they differ across multiple z15s despite being identical in hardware configuration. Can we manually assign APs to PCHIDs even if it requires a ...
