[SunHELP] adding another A5100 array

[Dan Angolano]

I am assuming you are concerned about controller numbers changing when you
flip around the GBIC's and reboot.  I have successfully changed controller
numbers out from under VxVM in the past.  My understanding of how it works
is; Volume Manager stores various volume, plex, and disk information in the
private region of each VxVM controlled disk.  This allows Volume manager to
handle changes to the underlying disk names without affecting the volumes.  

If my assumption was incorrect and you are concerned about something
else...sorry. :^)

Subject: [SunHELP] adding another A5100 array

I have an A5000 and an A5100 array connected to an ultra enterprise 3500.
Each array has 2 gbics in it, and the fiber cables are crossed so each array
is on two different SBUS cards in case of failure. I just bought another
SBUS card with 2 GBIC's in it and another A5100 array. I don't want to plug
both ports on the array into the new card, I'd like to get each port on a
different card.

Can I just move around the fiber the way I want and do a boot -r? Will this
screw up my volumes? (I'm running VxVM) Otherwise, how would I go about
this?
