Hi,
I am working on kickstarting RHEL4 servers with SAN-attached
disks. The disks hang off of Qlogic HBAs, for which there is a generic
qla2xxx driver being loaded. I would like to prevent the SAN disks from
being “seen” during the install – anyone know of a way to do that?
The *only* sure way I know of doing this is by blocking off the ports on the
switches while doing the kickstart. I've (or my co-workers) have hosed too
many SAN-disk-resident filesystems in the past trying to get around this
problem (which we only have on Linux; its never been an issue on AIX or
Solaris, but that's probably just because of the deterministic method of
device enumeration on those operating systems.)
You can use the 'nostorage' boot option, which will, shockingly, not load
any storage related drivers. In your kickstart, then, you'll need to use
the 'device' flag to tell it which storage drivers you *do* want to load.
