We have two HBA's on each VIO Server using NPIV (dual vios setup) and the Lpars virtual adapters are mapped to each , giving the Lpars four Paths (using MPIO on the client)
I need to document the steps to update HBA firmware without taking the VIO Server down
Does anyone know of a good site or where some doc is on this subject
------I figure I would run lspath on the clients and disable the connection to the HBA that will be updated.
------I would then unmap on the VIO Server (writing down the configuration)
------Update firmware (not busy so should update)
------Remove from the VIO Server than cfgmgr it back
------enable on the clients.
