• The minimum HMC level required to perform install or upgrade via network to HMC V10 R3 M1050 is HMC V10 R1.
  
  
• Minimum memory supported for vHMC is 16GB and disk size should be 500GB.
  
  
• HMC V10 R3 M1050 provides support for managing Power10, POWER9 & POWER8 processor-based systems.
  
  
• Management of POWER7 and older servers is not supported by HMC V10. Attempts to manage POWER7 and older servers will result in a connection state of Version Mismatch and connection_error_code “Connection not allowed 0009-0008-00000000”.
  
  
• HMC V10 R3 M1050 supports the following HMC models:
  
  • x86: KVM, XEN, ESXi (6.5 / 7.0 / 7.0.2)
  • ppc64le: 7063-CR1, 7063-CR2, vHMC on PowerVM (POWER8, POWER9 & Power10 processor-based systems)
  
  
• Starting with HMC V10 R1 M1010, 7042 models are not supported.
  
  
• 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 use all the new features available in V10 HMC ensure all Virtual I/O Servers are at level 3.1.3, 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. If the partitions are using TLS for RMC communication, then the RSCT version should be 3.3.2.0 which is the default version available in AIX7.3 TL2.
  
  
• Starting with V10 R1 M1010, HMC supports HTTP2 protocol along with HTTP1.1. Users or applications using CURL as the REST client may see connection issues depending on the versions of curl being used. Suggest using  '--http1.1' as the CURL argument if it fails to connect by default over HTTP2.
  
  
• Starting with V10 R1 M1010,  http response status message is no longer present in the Rest API response (which was an optional field for earlier versions).  REST API clients should depend on the status code instead of status message to validate the success/failure of the API.
  

• Fixed an issue that caused the VIOS Create Virtual Fibre Channel adapter GUI task to fail with the error "REST000B The URL presented to the Management Console REST Web Services is not valid".
  
• Corrected the values shown in the Storage I/O usage column on the Usage page of the Systems and Partitions tables in the new GUI dashboard.
  
• Fixed an issue with PCM energy metric sample collection for eBMC-based managed systems that caused SRC E3550046 to be called home.
  
• Fixed an issue causing the interpolation line and shading to be missing from Performance and Capacity Monitoring (PCM) graphs for some intervals such as last month, when accessing Performance and Capacity Monitoring GUI from old dashboard,
  
• Fixed an issue that can cause a shared processor pool name to be changed after a server firmware update.
  
• Fixed an issue preventing a partition from being set as a time reference partition on a managed system that does not support Live Partition Mobility but does support time reference.
  Disabled unused HMC port 5023.
  
• Fixed a timing issue that caused SRC E3D46FFF to be called home due to a call home failure that occurred because the Electronic Service Agent was not fully activated.
  
• Fixed an issue that caused SRC E3D45070 to be reported and called home during a Transmit Service Information operation due to a specified Product Engineering file being rotated or deleted during the operation.
  
• Fixed an issue causing firmware updates for Open Power systems to always fail with the error "HSCF0276E Failure during readiness check operation against target".
  
• Fixed an issue that causes the Update Access Key (UAK) to be resent to an Enterprise BMC based managed system every time the HMC performs a UAK check even though the UAK has not expired.
  
• Fixed a rare timing issue on HMC boot that caused SRC E3550046 to be called home.
  
• Fixed an issue preventing HMC-to-HMC communication on port 9920 when the HMCs are on different subnets.
  
• Fixed an issue where the HCNID associated with a migratable SR-IOV adapter is changed every time a partition profile with that migratable SR-IOV adapter is activated or applied.  With this fix, the same HCNID will be used every time, preventing duplicate network bondings from being created and preventing the creation of a new resource with a new MAC address.
  
• Reduced the time the partition dump restart operation will wait for a blocking operation to complete.  Now the dump restart operation will return a busy error if it must wait more than one minute for a blocking operation to complete.
  
• Fixed an issue that caused a Power Enterprise Pool 1.0 Mobile CoD pool processor or memory CoD code with a bad sequence number to be ignored and no error to be reported back to the user.
  
• Fixed an issue for a Power Enterprise Pool 1.0 with no memory that causes the error "HSCL9119 The Mobile CoD memory activation code for the Power enterprise pool was not entered because a permanent to Mobile CoD memory conversion code for a server could not be entered" to be returned every time a pool create, update, or recover operation is performed.  Also fixed an issue for a Power Enterprise Pool 1.0 with no processors that causes the error "HSCL9118 The Mobile CoD processor activation code for the Power enterprise pool was not entered because a permanent to Mobile CoD processor9 conversion code for a server could not be entered" to be returned every time a pool create, update, or recover operation is performed.
  
• Improved the error message displayed by the installios command when only the name of the directory on the HMC that contains the ISO image to install is specified as the source of the installation images (-d) instead of the entire path, including the file name, of the ISO image.
  
• When an Enterprise BMC-based managed system is powered off, its VMI IP address is no longer added to the list of removed IP addresses used for DHCP auto-discovery.  Note that this change has no functional impact since VMI IP addresses are not auto discovered via DHCP.
  
• Changed the error message that was received when activating a partition with vNIC adapters when the SR-IOV adapter logical port limit on the physical port has already been reached.  The original error message "HSCL2521 There was a failure in the management console repository" has been replaced by an error message indicating the limit has been reached.
  
• Fixed a rare issue causing notifications in the GUI Notifications slide in window to show a blank Reference ID and Source and a date of "Invalid Date, Invalid Date".
  
• Fixed an issue that always caused a Linux partition running in the Power10 processor compatibility mode to fail remote restart or disaster recovery validation on a POWER9 processor-based destination system.
  
• Fixed an issue that called home failure SRC (E3D46FFF) for a problem that is closed or duplicated in the backend.
  
• Added the missing -t io option to the lslic help text and man page.

Best Practices

• User sessions - The following best practices helps avoid performance degradation gradually over a period of time due to increased login sessions as well as security vulnarabilities 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.

Notes for the Virtual Appliance for PowerVM :

• On POWER9 and Power10 servers, HMC Virtual Appliance for PowerVM can run in Power8 and Power9 compatibility modes for this release.
  
• The HMC Virtual Appliance for PowerVM does not provide graphics adapter support for adapters assign to the partition. Use a supported web browser to point to the HMC for UI support.
  
• DLPAR operations such as memory and processor moves for HMCs running in an LPAR are not supported.
  
• Inactive partition migration and Simplified Remote Restart operations are supported.
  
• The virtual appliance for PowerVM requires a POWER8, POWER9 or Power10 server that is enabled for little endian support. Minimum System Firmware 860 recommended for Power8 servers
• You cannot manage the server that hosts the HMC virtual appliance.
  
• You cannot manage the server that hosts another HMC virtual appliance which is managing the server that hosts this HMC virtual appliance.
  For example, HMC virtual appliance A is running on server A and HMC virtual appliance B is running on server B. HMC virtual appliance A cannot manage server B and HMC virtual appliance B cannot manage server A at the same time. One of the HMC virtual appliance can manage the other server, but both HMC virtual appliance cannot manage each other at the same time.
  
• For HMC virtual appliances that are created on PowerVM, enable LargeSend on the NetworkBridge of the corresponding virtual network for better network bandwidth to the HMC virtual appliance.

General Virtual HMC notes

• Virtual HMC Appliance can be deployed in your existing POWER virtualized infrastructure. Virtual HMC Appliance supports install into PowerVM LPARs.
• Call home of serviceable events with a failing MTMS of the HMC itself is disabled.  Those serviceable events should be manually reported to IBM software support.
• To see if you are running on a virtual HMC use the lshmc -v command. If it displays a UVMID field, then you are running in a virtual machine.
  

  Example:
  

  lshmc -v

• When deploying a virtual HMC, if the mac address is not specified, it will be generated by the hypervisor.  Network configuration on the HMC relies on the value of MAC addresses. If you re-deploy a new virtual HMC and want to restore critical console data previously taken on a virtual HMC, ensure sure you are using the same MAC addresses.
• When using Activation Engine to setup NTP configuration, you must specify the NTP version value.
