List of fixes

General fixes

• Added the columns Permanent CPU, Permanent memory, Available CPU, CoD CPU capable and CoD memory capable to the Systems table Resources view in the new GUI dashboard.
  
• Fixed an issue that caused the number of virtual IO Servers column in the Systems table "All view" to always display zero when there are Virtual I/O servers but no other partitions in the managed system.
  
• Fixed an issue that causes an empty folder to be left in the /home/padmin directory on the VIOS following the creation of a full VIOS backup that includes NIMOL resources on the HMC.
  
• Corrected the NFS examples in the cpviosbk, cpviosimg, cpviosupd and updvios man pages.
  
• Fixed an issue that caused the chhmc -c network command to add and set a custom DHCP server address range for an HMC ethernet interface to appear to succeed but failed to set a static IP address for the range.
  
• Fixed an issue that caused SRC E35F0013 to erroneously be generated and called home after updating the HMC.
  
• Fixed an issue that prevented a user from using the GUI or REST API to assign a partition to a shared processor pool or modify the processor settings of a partition in a shared processor pool when the shared processor pool name has a space in it, resulting in error message: Error: REST019C Value ' shared_proc_pool_name=xxx ' is not valid for option ' attributes '.
  
• Fixed a save upgrade data failure with the error "Upgrade partition is full" when managing many systems and partitions where backups of profile data exceeded the space.
  
• Fixed an issue to that caused the import or export of VIOS backups to fail with the error message "HSCLA500 An internal error occurred. Try the operation again. If the operation continues to fail, contact your service representative." when a space was included in the Remote Directory name on the GUI.
  
• Changed the View Impacted Lpars task when doing a concurrent system firmware update to show no Lpars.
  
• Fixed an issue that caused SRCs E35A0083 and E332FFFF to be reported and PCM aggregated metrics to no longer be generated after DST ended.
  
• Changed the VIOS Validate Maintenance Readiness and Prepare task to return a warning message indicating that the HMC cannot compute vFC storage redundancy accurately for IBM i partitions.
  
• Fixed a timing issue that caused system firmware update to fail for some systems with the error message: "There are one or more systems without updates available that will be skipped".  This error can occur only when multiple systems are selected and a mounted repository such as USB or DVD is used.
  
• Fixed an issue with the Partition Migration Validation GUI task where after running Validate then Modify MSP to change the MSP selections, the selected MSPs are not saved after clicking OK to exit the Modify MSP panel.
  
• When a partition migration operation fails due to issues with the Trusted Platform Module (TPM), a detailed message was added to indicate that the failure was caused by TPM issues.
  
• Fixed an issue that caused the HMC GUI to stop responding and to generate SRC E35A0053.
  
• Fixed a rare timing issue that caused custom task role assignments for all HMC users except root, hscroot, and hscpe, to be set to "Undefined" after the HMC was restarted.
  
• Fixed an HMC performance issue causing general slowness across HMCs that have Performance and Capacity Monitoring (PCM) enabled.  
  
• Increase timeout when trying to arbitrate primary monitoring HMC for managed server in dual-HMC environment to avoid repeated call home SRC E3325009
  
• Fixed an issue where after upgrading to HMC V10R2M1030 any HMC scheduled operations that existed prior to the upgrade will fail to run and will cause SRC E35F0010 to
  be generated and called home each time they try to run. Note that just after the HMC is restarted to apply the update with this fix, there will still be one SRC E35F0010 generated
  and called home.
  
• Added support for PowerSC 2.1.0.4.
  
• Fixed another issue that can still cause the save upgrade data process to continue to fail due to lack of space when run after the previous attempt also failed due to lack of space when the
  space requirements were reduced.
  
• Fixed an issue that caused SRC E3020000 to be generated and called home when the lslic -c command was run and the HMC’s repository contained a mix of EC levels.
  
• Fixed an issue that caused some scheduled operations, and some transmit service information operations to run much more frequently than scheduled.  This issue occurs if the HMC time zone is changed after the scheduled operation or transmit service information operation is initially scheduled.
  
• Fixed an intermittent issue that caused an Enterprise BMC based managed system powered on with a system profile to transition into Incomplete state.
  
• Fixed an issue that causes 0x0314 error with the message
  "Return code type: Failure (hard stop or user intervention required).
  Message:
  The partition does not support a required management console capability level.
  Corrective action:
  Update the partition to the latest PTF level."
  This happens when RV CM operation is performed on a machine with a MEX attached and the MEX resources are in use by IBM i partitions the first time after the system has been powered up.
• Fixed another issue causing the generation and call home of SRCs E23D040A, E2FF4600, E2FF1409 and E2FF4406.
  

Best Practices

• User sessions - The following best practices helps avoid performance degradations gradually over a period of time due to increased login sessions as well as security vulnerabilities such as unauthorized access to the active HMC sessions.
• It is a best practice to logoff from HMC UI and then close the browser tab instead of directly closing the tab
• Set Idle session timeout for all the users and not leave the timeout as '0' which leaves it as no timeout.
