Reason: In order to run future versions of VMware ESXi software on our HP hypervisors, we first need to upgrade the BIOS and iLO firmware.
This maintenance will cover firmware updates on the Milton Keynes hosts using an HP-provided SPP (Service Pack for ProLiant).
Impact: During this change window, hosts will be placed into maintenance mode, vMotioning the virtual servers to other hosts. Due to the sensitive nature of voice servers (SBCs) during such moves, a minor registration dip could occur, however this is unlikely.
Checks: Monitor host health via ILO and Vcenter GUI
Rollback: If firmware upgrade fails HP Proliant servers will revert back to their last known bios ROM version ILO config or back up file.

Rollback: If the BIOS firmware upgrade fails for any reason, the HP server will revert to its last working BIOS ROM version before the upgrade. The ILO config however, might need to be rolled back via the backup file created.

Reason: To upgrade the EvolveIP ESXi infrastructure to the latest firmware patch level provided by Broadcom
Impact: Hosts will be updated one at a time and in maintenance mode, no impact to customer should be expected but given the nature of live service servers being migrated there might be some degradation to services during the vmotion process.
Checks: Check host HA and DRS status
Check Vcetner GUI for any errors and take action to resolve
Check Veeam for any errors and ensure it cans till see both clusters
Rollback: Should the lifecycle controller be unable to install the patches then the manual method should be taken.
esxcli software profile update \
-d /vmfs/volumes/datastore1/"patch zip file to be entered here \
-p Patch name \
--dry-run
check for any errors and proceed if none:
