Avoid Remote VL CP Penalties By Utilizing Local Resources When Drawer Fit Fails

On IBM z16 servers, we have observed a significant increase in the cost of accessing data/memory located in a remote drawer. In certain scenarios, this can result in a notable increase in CPI, leading to an LPAR’s CPU utilization doubling -or even...

Enable System Recovery Boost for DMR Events Triggered By Drawer Swaps

On IBM z16 servers, we have observed a significant increase in the cost of accessing data/memory located in a remote drawer. In certain scenarios, this can result in a notable increase in CPI, leading to an LPAR’s CPU utilization doubling -or even...

Allow custom TCP Ports for SFTP Boot

HMC should allow to add custom TCP Ports to boot from an SFTP source. At the moment, it just uses TCP Port 22 but when the customer runs his SFTP/SSH Server on a non-standard Port, the HMC is not able to connect.Ideally the HMC allows entries like...

Ability to configure a log off on idle user (automatic logoff after timeout) on the HMS/SE

Our customer was asking for this option - is it available - how can it be activated/ deactivated (case TS018530378) It appears it is not possible to configure and idle user to be logged off from the HMC/SE - for me it makes perfect sense to have t...

Add link encryption capabilitys to coupling express adapters

As of today, coupling express (LR and SR) adapters are not capable of link encryption functionality. The sysplex functionality of logically encrypting CF structures like LIST and CACHE structures is good but does not cover the need to have "everyt...

Extension of "Manage System Time" tab overview with NTP configuartion on z16 oscillator cards

Beginning with IBM z16, the STP physical connection to the time servers (PTP or Network Time Protocol (NTP)) is no longer established through the HMC. The time servers are connected now directly to the CEC (bypasses the SE connection).So each of t...

add a TN3270 configuration option to disable the check for Server name & Certificate name to match

Configurable Option to disable Verify Certificate We have encountered a situation with our TKEs at RBC. We had LPAR site certificates included in the TN3270 ring before and removed thus only TN3270 user certificate is in the keyring. More specific...

LDAP Server Definitions - Different Ports and SSL for Primary and Backup

With the current configuration options I'm able to define two hosts (primary and backup) however I'm only able to define a single port which must then match for both hosts. I need the option/flexibility to assign different settings for each host l...

Notification Of A New MCL Release (HMC/SE)

Would it be possible to get a notification when a new MCL Bundle has been released for HMC and SE Code for zSeries Mainframes? This would save checking z15, z16, z17 and HMCs to see if there has been a new MCL Bundle released for anything. The not...

LDAP Server Definitions - Allow testing and validation

With the current option is only possible to define the Primary and Backup hosts with a port and separate Bind DN. It would be great to offer the function to test the connection (with a ping for non-SSL and a handshake for SSL connections) and vali...
