Hi There,
We have few ESX hosts. We have just tried upgrading them to latest version (5.5 update 2). Below steps followed...
Update iRMC/ILO of physical blade servers
Update BIOS of the physical blade
Update 2 from Update Manager.
It worked good till now, without any issues.
As soon as we try to update next available update through baseline, HBA's went on missing. (i.e. datastore missing from esxi)
Anyone has any suggestion or has come across such scenario.
