RE: Replacing a pair of 5903s with a pair of 5913s

["Jim Oberholtzer" <midrangel@xxxxxxxxxxxxxxxxx>]

Use the replacement procedure in the HMC for the cards.  Since they are
different you might see some complaining about the RAID set being from a
different card.


BIG CAVEOT!!!!!!   Be really, really, really, no really sure you have
flushed the cache on that card before you swap it.  If it's not flushed,
reload time.......
