Hardware : HP DL380 Qlogic qla2300 type HBAs (two of them) 'cciss' driver internal raid I'm kickstarting an install to the internal raid 0 drives. The qla2300 HBAs are both pathed into a SAN that will present disks, but which shouldn't be touched at all during install (data disks). I find two symptoms : 1) install probes the various scsi luns presented by the HBAs off the SAN, and pops up dialogs complaining when it can't access them as it expects This interrputs the unattanded kickstart 2) The MBR does not get written out correctly to /dev/cciss/c0d0 at the end of the install. My working theory so far is that the order of detection of the scsi_hostadaptors (qla2300 then cciss) is messing things up. I confirmed by looking at /etc/modules.conf on a system built when there were no LUNS presented by the SAN : alias scsi_hostadapter qla2300 alias scsi_hostadapter1 cciss alias scsi_hostadapter2 cciss_2445 So my guess is that it's attempting to write the boot record to /dev/sda (first lun off qla2300 device).. this would be pretty damn bad if there were actual live data that we cared about there :) So I need qla2300 to be below all of the others, and I need it at boot time of the install kernel, in order for this to run smoothly, unattended, and not mess with the san disks regardless of what LUNs are presented. All help greatly appreciated. Cheers, Al
