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.
Huh, interesting, never heard of that. Google gives more info, but
from what I see, I think I'll still feel safer doing the port block.
Sounds like this could be a good solution for many of these situations.
