15. If you have 7133 D40 or T40 disk drive enclosures type the
following commands

cd /etc/microcode

ssa_sesdld -u -f coralXXX.hex (where XXX is the highest number that you
have in /etc/microcode)

16. To install latest level microcode to all SSA drives, run ssadload
-u from each system in turn.
NOTE: ALLOW SSADLOAD TO COMPLETE ON ONE SYSTEM BEFORE RUNNING IT ON
ANOTHER
