ok, let's start again... here is a different but functionally equivelant
scenario:
imagine you two machines, A & B:
machine A boots off IDE, and has a SCSI card with an external
chassis with 10 drives in it.
machine B boots off IDE, and has a SCSI card but nothing plugged
into it.
machine A is configured to have a vinum RAID using only disks on the
SCSI card, as per my previous emailed config.
machine B is a fresh install, with no vinum configuration.
describe the procedure for unplugging the external chassis from machine
A, and plugging it into machine B, and bringing up the vinum RAID
without re-initialising it (i.e. preserving the data already on it). the
only data you may take from machine A is the vinum config as per my
previous email.
cheers,
Adam
