Hypervisor Firmware Upgrades (London HEX)
Scheduled for Jan 28, 22:00 GMT - Jan 29, 03:00 GMT
Scheduled
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.
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 Vcetner GUI
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.
User actions: N/A
