My colleague has a server with a bunch of SAN disk.
He's getting a new server, but the associated disk is
"delayed in delivery", so he is considering migrating
a LUN or two from the first box to the second.
Looking at SUN docs about cfgadm, we did not
find a way to "unconfigure" a single disk.
One option is to have the LUN revoked from
their group, and then boot -r, but that's agressive
and impacts uptime.
Our two questions are,
a) Is there a way to do this? (The docs don't say
that you CANNOT specifiy exactly one disk/Lun
for unconfigure, but they don't offer an example
b) Is there harm if we DON'T do it?
i.e., pretend it is now a Highly-Available Disk,
and just ignore it on Server1, and use it on server2.
(My group runs lots of HA, and 90% of the time,
a disk is potentially accessible on the backup server
but never touched.)
(BTW, they are not using Veritas for this disk,
it will be a Sybase disk probably.)
Thanks
Seth
