RE: Install to local drive instead of a fibre attached SAN



That helped.  I didn't have the terms to search for.  There's a boot option "nostorage" that will skip disk drivers.  You then put "device scsi qla2300" to load only Qlogic as "/dev/sda" or "device scsi qla2300:mptscsih" to load both Qlogic and mptbase cards.  I do NOT find that this method allows you to specify Qlogic as "/dev/sdb" or "/dev/sda" in a two-controller list.

I also stumbled across a native kickstart boot option "latefcload", which loads fibre channel drivers last among all scsi modules.  This is a good basic way to install the OS on local drives without having to worry about nuking an attached SAN volume.

Thanks, Stephen.

I did a quick google. Try passing "nostorage"

My environment is RHEL 4U4 on mixed 32- and 64-bit Intel hardware.  Is there a way to script in %pre the exclusion of drives attached by an HBA?  I've rewritten /tmp/modprobe.conf with "scsi_hostadapterN qla2300" as both first and last entry in the scsi hosts, but the lettering of the drive doesn't change.  It appears to be set by the kernel image during boot.  Can that be re-ordered?  The closest thing I've found is that I can 'rmmod qla2300' in %pre, but the better long-term plan would be to configure internal or external by choice so we have the option of installing to the SAN later.
