You always want to insure that the machine comes down clean, and I guess the
warnings are that the cache is properly flushed from the existing cards.
That said, I usually do a ENDSBS *ALL first so that everything is ended, and
then do a PWRDWNSYS *CNTRLD with 180 seconds (this is just to make sure
everything is written to disk, and gives system plenty of time to come
down). Then, I just installed the card (usually trying to keep the cards
together) and put the cable from the 4th SCSI port (it's the furthest from
you when u have inserted the card into a 5094 tower) on the card and that is
it.

Subject: 5581 (5780) Installation - 2757 Cache Card
Hi
I will be installing a 5780 Cache card to our systems here to connect to our
current 2757 Raid controller, whch will inturn make it now a feature 5581.
I have completed an LVT and ensured that the card is on the same bus and in
the same partition as the 2757, and also made sure that there is a slot
available to put it in.
Is it just a simple case of powering down the system, installing the cache
card, cabling it to port 4 of the 2757 and then bringing the system back up?
Or should i stop RAID first, then add the card, and then restart RAID across
disks with the cache card?
Also, are there any post installation tasks that I need to do? Things in DST
or System Values that need to be changed to make it work correctly?
I have found a link in InfoCentre, but there are lots of warnings it might
mess up the disks, but no clear installation details?
