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



fixed

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.......

The system is HMC Managed

The process may be slightly different depending if your HMC managed.
If HMC, wizard will step you through.
If nonHMC, then you need to check concurrent maintenance process for
nonHMC managed.

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

Hi All

I'm replacing a pair of 5903's with a pair of 5913's in a 750;
intention is to allow an additional 5887 tray to be attached to the
system.

The 5903 cards are housed in a 5877 and the partition owning the cards
will be powered down to effect the change. There are cards owned by
other partitions in the 5877.

Do I need to power off the entire 5877 and therefore shut down the
other partition as well, or am I OK to replace the cards once the
owning partition is powered down ? Should I/can I power off the
individual slots as part of the install ?

The pre-reqs page also tells me to verify the firmware on the 5877 is
at the right level - does anyone have any hints ore references as to
how I would determine this ?

The partition the cards will be assigned to is running V6R1M1 and will
be updated to resave level M prior to the hardware change, along with
the latest cume, hiper and group PTFs.

Any and all advice appreciated.
