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.
