Hi,
based on what i see is your BIOS or FW update wiped the NSD descriptor
by restoring a GPT table on the start of a disk that shouldn't have a
GPT table to begin with as its under control of GPFS.
future releases of GPFS prevent this by writing our own GPT label to the
disks so other tools don't touch them, but that doesn't help in your
case any more. if you want this officially confirmed i would still open
a PMR, but at that point given that you don't seem to have any
production data on it from what i see in your response you should
recreate the filesystem.
However before recreating the file system I would run the script to see
if your disks have the secondary copy of the GPT partition table and if
they do make sure it is wiped/removed *BEFORE* you go any further.
Otherwise it could happen again...
