One of the tasks that we had to deal with during the last trip was to expand SB40c blade storage by replacing 4x146GB SAS disks with 6x30GB SAS disks.

Plugging HP-UX into SAN

Our task for today is to connect HP-UX (11.31 release) to MSA2312fc through SAN with two Brocade switches in between. First, we need to find out all FC cards installed in our server and once we have that piece of information we could dig for WWN numbers to map them latter to the disk array. […]
