Hi!
I have a question for you. No rush on this one, not doing it till
January.
We are moving from software mirroring of system disks (using LSM)
to hardware mirroring (KZPAC controllers). I know when I broached
this, pretty much everyone said "Don't do it! KZPAC sucks!" etc., but,
well, we have these things now and we are expected to use them.
System: cluster of two 4100s with shared SW800 cabinet using HSZ
controllers and local system disks on KZPAA controllers (to be
replaced with the KZPACs). Unix 4.0E patch 2.
When we have de-encapsulated and un-mirrored the system disks
using LSM, we wanted to just stick the KZPAC controllers and
split bus shelves in the systems and then just pop the newly
unmirrored system disk in the controller and add it to the array and
boot. Digital say "no way it will boot without init-ing the disk, i.e.
wiping it, so you will have to back up your system disk, init the disk
and then copy it back.
What would you say is the most efficient way to do this? I was
wondering if we could init a disk on the HSZ controller, copy the
files (just using cp -pR ? or vdump, cpio etc.?) from the old system
disk to this HSZ-inited disk, then switch the controllers and pop the
disk i just copied into the KZPAC and boot it. Think this would
work? Any better ideas/gotchas etc.?
Thanks, will summarize
John
