• This HMC Version V9 R2 M950 ISO is only supported for the 7063-CR2 hardware. The 7063-CR2 ships with this image and Service Pack 1 installed. If a reinstall is required only use the fresh installation of this image option and reinstall SP1 or higher immediately after.
• If migrating from CR1 to CR2 ensure the CR1 was installed at V9R2M950 + SP1 prior to running the saveupgdata –migrate option.
• This image includes all fixes from V9R2M950 base up to and including V9R2M950.5. Updates to this base level are allowed starting with V9R2 M950 SP1 Service Pack MH01874 or higher.
• Example procedure for creating a bootable image for this Recovery media to reinstall a 7063-CR2 with V9R2M950 can be found here.
• HMC V9 R M950 supports POWER7 servers with the following minimum firmware levels:
  
• FW730_146 (730.A0)
• FW740_156 (740.90)
• FW760_087 (760.50)
• FW770_098 (770.50)
• FW780_068 (780.21)
• HMC V9 R2 M950 continues to provide support for POWER8 and POWER9 processor-based systems.
• All remote browsers, scripts and programs that interface with HMC REST APIs or web browser (including HA programs, AIX Live Kernel Update, etc) require enablement for TLS 1.2.
• Management of POWER6 and older servers is not supported by HMC V9. Attempts to manage POWER6 and older servers will result in a connection state of Version Mismatch and connection_error_code “Connection not allowed 0009-0008-00000000”.
• If two HMCs manage the same server, both HMCs must be at the same version, release and maintenance level.
  

• It is recommended to have all connected VIOS servers on the latest level i.e., Virtual I/O Server (VIOS) level 3.1.x. To have optimal performance from the GUI, ensure all Virtual I/O Servers are at level 3.1.1.x level, or later.
• All running partitions (AIX, Linux, and VIOS) should be at Reliable Scalable Cluster Technology (RSCT) version 3.2.0.0, or later. It is recommended to have AIX 7.1 TL4 or higher and AIX7.2 TL0 or higher; these levels contain RSCT 3.2.1.0.

• Limit new managed resource role and task role names to 47 characters.
  
• Added additional validation for the -h parameter on the chhmc -c syslog -s add command to return an error if a comma-separated list of host names is specified.
  
• Fixed an issue where a UI DLPAR memory operation times out at 30 minutes even when the command timeout is greater than 30 and the command is still running. The UI task reports message REST0255 An internal error occurred.

Previously released fixes also included in this recovery media image:

Security fixes

• Addressed tomcat vulnerability: CVE-2020-9484
  
• Addressed a problem in the authentication flows to avoid thread hung/idle state during access server calls.

Command line changes

• The following new commands have been added to support partition virtual serial numbers: lsvsn, rmvsn, xfervsn.
  
• The following existing commands have been enhanced to support partition virtual serial numbers: chsyscfg, lscod, lssyscfg, mksyscfg.
  
• The following commands have been enhanced to support partition keystores: chsyscfg, lssyscfg, mksyscfg, rstprofdata.
  
• A new option has been added to the lslparmigr command to display memory requirements for a partition to be migrated as well as available memory on a destination managed system.
  
• Enhanced the lslparmigr -r msp and lslparmigr –r lpar commands to display MSP thread information.
  
• The chsysstate command to power off a managed system has been changed to fail if the managed system is currently offloading a dump to the HMC. To override this new behavior and power off the managed system anyway, specify the --force option on the command.
  
• New options have been added to the chled and lsled commands to support identify LEDs.
  
• New options have been added to the chled command to run an LED lamp test.
  
• The chhmc command no longer allows the SSH protocol version to be set to 1, Kerberos weak encryption to be set to on, or the legacy anonymous cipher mode for the HMC chatlet interface (port 9920) to be enabled.
  
• A new option has been added to the chsvc command to automatically add the required certificates to the HMC's truststore when the cloud connector encounters a non-trusted certificate chain when connecting to cloud endpoints.
  
• The chhmccert command has been enhanced to support adding and removing certificates to and from the HMC's truststore, and the lshmccert command has been enhanced to list the trusted certificates added to the HMC's truststore.
  
• The chhmcfs and lshmcfs commands have been enhanced to support the /data file system and to support the /var/hsc/log file system as the separate file system that it now is (/var/hsc/log is no longer in the /var file system). Prior to this enhancement, these commands included the /var/hsc/log file system with the /var file system.
  
• New options have been added to the chsacfg and lssacfg commands to configure and display connection monitoring settings.
  
• New options have been added to the chsvcevent command to add a comment to a serviceable event when closing it.
  
• The lssvceventfile command has been added to list the contents of a file associated with a serviceable event.

• The BMC can appear to hang with a blank black screen when accessed through the remote KVM in the BMC when the user logged in has an idle timeout set and the screen lock is triggered. Rebooting the BMC is the workaround.
  
• Only one KVM session through the BMC can be used at a time. Another user is not prevented from stealing an existing session.
  
• Fresh installation of the Recovery image can report SRC E332FFFF. There is no user impact, close the event and ignore the SRC
  
• The Setup Wizard may end prematurely and log call-home SRC E35510D4. The settings are saved correctly, there is no user impact, the SRC can be ignored, close the event.
  
• The Virtual media function cannot be used to install Service Packs or PTFs only Recovery media.
  
• Occasional Out of Memory Exception during Virtual I/O Server Installation when user logs out or the session expires.
  
• Proxy time out issue when multiple mappings are created or deleted as part of single POST operation for the same RR partition.
  
• "Internal error" message is observed, on removing stand alone vSCSI client adapter from inactive AIX partition.
  
• A failure occurs during a pool (CPU/Memory) update operation that prevents adding the resource to the server
  
• REST API error messages are not translated to the language of the browser or HMC.
  
• In SRIOV Logical port advanced settings, Promiscuous Mode field is missing in add VIOS wizard.
  
• During partition deployment, user will not see the configured client slot id for SCSI adapters when Remote Slot ID is configured to next available ID.
  
• Launching UI task might show errors for a server (General Settings, Processor, Memory,I/O, Virtual Networks, Virtual NICs) in some specific scenarios with running Linux Partitions post LPM operation. Remove the system connection and add it back as a workaround.
  
• The validation fails for IPV6 address in the NetBoot wizard, when the user enters the prefix along with IPV6 address. The user can provide an IPV6 address in Unicast Addressing excluding the prefix as a workaround. Fixed in SP1
  
• Accessibility: In some panels, navigating to different input fields by TAB key doesn't work
  
• Customer may observe multiple heapdumps and javacores if there is any OutOfMemory for a service. It can result into triggering of SRC "E332FFFF" multiple times.
  
• Occasionally, during lpar activation, command execution becomes very slow affecting HMC performance.
  
• Error launching task message is thrown in Partition virtual storage topology diagram page.
  
• Occasionally, user shall see that System level Hardware Virtualized IO tab takes more time to launch.
  
• Automatic installation of HMC using Activation Engine fails to process the configuration file. If the installation using activation engine presents you with a license to accept, then there is a possibility that the Activation Engine ISO image deployed cannot be mounted. Try to install again by rebooting the partition.
