Downloading microcode to SSA disk fails.
ENV: 7013-J40, 7133, 4.1.5, SSA RAID
Customer is attempting to update the disk drive microcode
for his drives from 6561 and 8473 to 8372. This worked on
the first 7 drives (pdisk0 to pdisk6), but failed on the last
one he was trying to upgrade the microcode to (pdisk7).
Customer is trying to download the microcode using the
ssadload -d pdisk7 -f /etc/microcode/ssadisk.ros.DFHC.8372
I had the customer shutdown system, power cycle all 7133's
and then bring the system back up and try to update the
microcode only to the pdisk that failed.
Customer was trying to change the microcode level for the
drives that were at level 8473 to match the level for his
other drives which were at level 8372 using the 'ssadload'
command. This failed as it did before.
The reason for the two different levels is due to there being
two different types of drives and corresponding microcode
levels. These microcode levels are dependent upon the type of
drive being used. Therefore the customer cannot make all the
levels the same due to the different types of drives.
The (8372) level of disk drive microcode will download to the
disks with the (6561) level of microcode, and is required when
the disks will be in a RAID configuration. The 2 different
levels can be mixed in a RAID environment and does not create
None; closing call.
