Description of problem:
I have some PowerEdge 2550 servers. These servers have both the internal
PERC 3Di raid and a PERC 3Dc card in them.
I am working on creating a Kickstart CD and I have a problem with the
order of how the raid devices are installed. The PERC 3Dc (megaraid) is
found first and gets set-up as /dev/sda, the PERC 3Di (aacraid) get
detected second and gets set-up as /dev/sdb. I need to get the 3Di to be
/dev/sda during the install. I have tried the
scsihosts=aacraid:megaraid:aic7xxx on the boot prompt, but it doesn't
seem to work.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot the bootdisk.img from a standard RHE3.0-WS CD
2. At the boot: prompt type vmlinuz scsihosts=aacraid:megaraid:aic7xxx initrd=initrd.img
Actual Results: The install will start, but the megaraid device is setup as /dev/sda and the aacraid device is setup as /dev/sdb
Expected Results: The scsihosts parameter should have set the aacraid device as scsihost0 and allowed the kernel to set it up as /dev/sda.
The scsihosts kernel parameter is only relevant when drivers are compiled into
the kernel and has no meaning if you're using modules (which we do).
Then how are you supposed to control what device gets assigned to what during an
unattended install? The device parameter in the kickstart file does not work either.
'linux noprobe' + the device parameter will let you get related results to what
you're looking for.
I have tried the 'noprobe' option with a kickstart file that looks like this:
append ks=cdrom:/nfs-dell-ks.cfg initrd=initrd.img noprobe
#kickstart file (partial)
langsupport --default en_US.UTF-8 en_US.UTF-8
device scsi aacraid
device scsi megaraid
device scsi aic7xxx
device eth eepro100
device eth bcm5700
mouse genericwheelps/2 --device psaux
network --device eth0 --bootproto dhcp --hostname nfs-basic
The kickstart install does not find any drives with this setup. Should I open a
different bug for this problem, since scsihosts was not the problem?
