How to change HP ILO Ips for OA, blades and interconnect modules

Recently I was working on changing HP c7000 enclosure onboard administrator (OA), individual blades and interconnect modules ILO IPs. It’s straight forward but I would like to share my experience here.

****  Before doing anything further in production/ working environment, take the backup of Virtual Connect (Flexfabric) as per this link 

Notes:

1.            From a networking point of view, all IPs are going to be in the same subnet. Here in this scenario, I have pre-configured two switch ports with new subnet and as part of the implementation I’ll connect 2x OA to new ports

2.            Version - OA 3.11
( If you are looking change blade name in HP Onboard Administrator, refer to "Steps to change blade in on-board administrator)

Step1: Change OA IP.

•             Login to HP OA

•             Verify OA failover to make sure both OA’s are still working after initial implementation ;-). I know our friendly BAU team hardly tests/ patch the environment

•             One more point to note, when you are doing OA failover test, it’s not necessarily your active OA IP will go onto passive OA IP based on below setting

•              Navigate to enclosure TCP/IP settings

•             Change standby on-board administrator ip to new one

•             Connect network cable to newly allocated port

•             Make sure that able to ping new IP

•             Failover OA to standby

•             Change active OA IP to new one

•             Connect network cable to newly allocated port

•             Make sure that able to ping new IP

•             Failback OA to its actual active OA

Step 2: Change individual blade IP

•             Login to HP OA.

•             Navigate to Enclosure Bay IP Addressing

•             Change Device bay IP address to new ones according as allocated

•             Make sure that able to ping new IPs

Steps 3: Change interconnect module IP (Virtual/ flex connects)

•             Login to HP OA

•             Navigate to enclosure TCP/IP settings- Interconnect bays

•             Change Device bay 1, 2, 3 and 4 IPs to new as pre allocated.( Note : Device bay depends on how many modules you have)

•             Make sure that able to ping new IPs

Update respective DNS alias with new names for all the above devices.
