- Fixed LDAP user creation using HMC CLI to ensure the user
inputs is validated.
- Users configured for Kerberos authentication that have an
expired password will fail to logon with a generic logon
failure message. The user must reset their kerberos
password to log on to the HMC.
- Fixed an issue when lslic is run against the same server
at the same time from the same HMC where one instance
performing cleanup of downloaded files will cause the other
instance to fail and return "unavailable" with rc=0.
- Fixed a rare issue with the controller HMC for a Power
enterprise pool that caused the HMC GUI to become
unresponsive and eventually to hang. This problem can
occur when there are a large number of HMCs managing a Power
enterprise pool and there is an HMC that is not responding
to Power enterprise pool requests from the controller HMC.
- Improved Remove and Add FRU performance on IO adapters
used as VIOS backing devices with variable times.
- Fixed "pedbg -c -q 8" command execution that throws error
while collecting the Cloud Connector logs.
- Revised the wording on an an email notification for
Serviceable Events when an Infocenter explanation is not
available.
- The HMC will now send a notification when a new service
event occurs but is held for call home approval by Events
Manager for Call Home.
- Improved the error message returned on a LPM operation of
an IBM i partition where the migration readiness command
times out. The old message was a generic "HSCL9001
The operation has failed on the management system".
The new message is "IBM i partition {0} failed to
respond the management console's request to perform a
check for migration readiness. The partition is not ready
to be migrated at this time. Try the operation again
later."
- Fixed a problem where a DLPAR add memory error was not
reported for IBM i partitions.
- Fixed a rare issue that caused a Power enterprise pool to
be deleted from the HMC during a restart of the HMC.
- Updated the rrstartlpar command man page to
document the existing return code of 93. A return code
of 93 indicates that remote restart validation was
successful, except for virtual fibre channel adapter and
storage validation which could not be performed because the
partition was active on the source system.
- Fixed the partitions view table issue where the top row
was being clipped off when there are more partitions than
the grid can hold at a time.
- Fixed a generic "00FF unknown error" message, when
user opens 5250 IBM i Console for the same partition that is
already open on another HMC. The new message is "Too many
connections".
- Fixed an issue with SRR/DR operation that was restarting
with the previous collected data which is stale.
- Fixed an issue that causes the HMC to report E212E161 SRC
due to too many open files.
- Fixed an issue with creating sysplan resulting in
exception : "Exception Occurred - Message: null Cause:
null" when a partition name contains a comma
character.
- Fixed an issue that caused the threshold value to be reset
when another threshold value is modified from the modify
Cluster Tier wizard.
- Fixed location codes visibility issues in the IBM i Tagged
IO panel, when the IBM i partition is having Physical IO
connected to it.
- Fix hardware clock not in sync with NTP
- Fixed an issue where webui ciphers are reset to default
and any previous changes are lost, after a service pack or
iFix is applied.
- Fixed an error on deploy system template where the deploy
fails with "REST0126 Please find error details below [An
error occurred while creating the partition named {}. ,
HSCL1466 The partition specified is not valid. Rebuild the
managed system and try again. ]"
- Fixed an issue with stale vNIC mapping during remote
restart or DR restart when the respective backing device has
been modified using dlpar.
- Fixed a rendering issue with vterm on a local hmc session
where it renders as a long vertical window with the font
double spaced when any command is executed.
- Fixed an issue where a virtual network may show 802.1q
tagging true when it is not tagged.
- Fixed error "HSCL3670 There was an error
accessing the management console persistent storage area."
that prevented user from changing SR-IOV physical port
attributes via UI or CLI when RoCE adapters are used.
- Fixed PCM dashboard opening issue seen only in certain
languages such as Polish, Italian, etc.
- Fixed an issue with the network boot of a partition via
GUI causing failure when 'no' is selected for "Would you
like to configure the client's network after the
installation [yes]/no? " option.
- Fixed a rare problem where performing concurrent
bi-directional LPM with redundant MSPs may intermittently
fail with error message "HSCLB98A The redundant mover
server partition (MSP) mapping selection is not valid.
When using redundant MSPs, the same number of source and
destination MSPs must be selected for a migration
operation."
- Add function to chprimhmc command to allow a user to
initiate primary monitor arbitration for which HMC processes
problems events from the server.
- Fixed an issue where a HMC shutdown or restart may be
delayed for up to 10 minutes if a serviceable event without
a parts list is received just prior to the reboot.
- Update logic to report serviceable events that arrive
within 5 seconds of each other that share the same reference
code but report different locations. HMC will report
these as separate service events instead of duplicates of
the first.
- Fix trap description translation issue with add SNMP trap
panel.
- Fixed an issue with deploy partition template with an
empty partition name. An error message is shown to the
user but after pressing cancel on the error the create
partition can not be used to create the partition.
- Fix an issue where updating HMC using virtual media on CR2
fails with "Media Services Error. The media contains an
unrecognized filesystems. Please make sure that the media
is properly formatted.
Would you like to try to use the media again?
ACT02065"
- Fixed an issue with the HMC Guided Setup wizard,
where if the user enters an SMTP server and port and then
add /edit/ remove emails, the server and port changes will
be lost.
- Fixed an issue where two users, on two different sessions
using the same hmc user, deploy partition template at same
time to same server can cause the deploy to fail.

Performance & Scale
- With V9 R2 M950 or later, a single HMC can manage up to
48 systems & 2000 partitions across the systems being
managed by HMC with minimum requirements as below
- 16GB memory for 1-500 partitions
- 32 GB memory for 500-2000 partitions
- For maximum number of systems and partitions when HMC is
used in combination with CMC, PowerVC, VM HA/DR, please
refer to the corresponding product documentation. For
other configuration requirements for Version 9 Virtual HMC
Appliance, please refer to Installing
the HMC virtual appliance.
Known issues and Limitations
- System firmware cannot be updated on both BMC and FSP
system types at the same time from the firmware update
wizard.
- Restoring the SSP backup on VIOS can fail at the first
attempt with RMC going down. When such an issue is
observed, wait for RMC to come up on its own (RSCT
services on VIOS restarted on its own) and retry the
restore.
- While removing a virtual network, UI shows "Internal
error" when there is a stale trunk adapter in the
system. Reloading the UI or refreshing the browser
should solve the issue.
- User shall see Various Invalid Validation errors when
configuring the backing device capacity for VNIC in
Deploy Partition Template Wizard.
- When configure multiple logical ports in Deploy
Partition Template panel, issue can be seen with
available capacity.
- In the GUI, last RoCE logical port remains in the
table view, even after removing it. Refreshing the
browser should clear the table.
- After PCM data migration from HMC 942 to 1010 level,
PCM data fails to be retrieved.
- In the Add Network wizard, moving back and forth the
panels causes incorrect values to be displayed for
802.1q vlan id and load group.
- Login fails if the Kerberos username is different from
the remote user id even though password and other
configurations are correct. Make sure both Kerberos user
id/name is same as id/name of the remote user.
- Rarely, following backup restore, attempts to login
fails from GUI. Users will have to restart HMC to
restore the access.
- Hardware images for 78D8 and 78D6 are missing in the
sysplan viewer under Hardware section in sysplan view
from GUI.
- When a Kerberos user attempts to login with an expired
password an access denied message is shown instead of a
password expiration message.
- If current encryption in webui cipher is set to only
one cipher TLS_DHE_RSA_WITH_AES_128_GCM_SHA256 , HMC
will not work with error as SSL_ERROR_NO_CYPHER_OVERLAP.
Adding back the other removed ciphers manually will
solve the problem.
- When addressing Power Interface Card Cable related
errors on System Control Unit (i.e.:
U78xx.SC1.xxxxxx-P1-C1-T1; U78xx.SC1.xxxxxx-P1-C2-T1),
Repair Panel (both Repair & Verify or Exchange FRU)
cannot be launched from the System Control Unit end
where the hardware location cannot be found. Workaround
is to launch the repair panel from the System Node end.
- The reset of an expired password of a Kerberos user is
not supported in multi-realm configuration setups since
release V9 R2 950. When such users try to login using
GUI, they will get message as Invalid credential. Upon
login from CLI, users may see below or similar messages.
Password:
Password expired. Change your password now.
Current password:
Current Password:
Password change failed. Server message: Old
password not accepted.
Current Password:
Password change failed. Server message: Old
password not accepted.
Current Password:
New password:
Retype new password:
Password change failed. Server message: Old
password not accepted.
Circumvention: Change or reset the password
first, then log into HMC.
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
"vpd=*FC ????????
*VC 20.0
*N2 Fri Sep 17 07:19:44 UTC 2021
*FC ????????
*DS Hardware Management Console

"
- 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.
