[Xen-users] Dom0 lvm/software raid rhel4.1 booting issues.

[Michael Montgomery <mmontgomery@xxxxxxxxxxxxx>]

Basically the issue comes down to my Volume Groups not being found by 
this initrd, causing good ole kernel panic.
initrd-2.6.12.6-xen3_12.1_rhel4.1.img

[root@xen01 lvm]# uname -a
Linux xen01.inside.***.com 2.6.9-22.0.2.ELsmp #1 SMP Thu Jan 5 17:13:01 
EST 2006 i686 i686 i386 GNU/Linux
[root@xen01 lvm]# cat /etc/redhat-release
Red Hat Enterprise Linux ES release 4 (Nahant Update 2)

Everything was installed by the rpms, as I've done another machine that 
wasn't scsi, and had this work fine.
The part I'm worried about is this:

"  Couldn't find all physical volumes for volume group VolGroup00."
I have sda, and sdb in a software mirror, as shown below, and I'm 
thinking that has something to do with it.
[root@xen01 ~]# pvscan
 PV /dev/sdc1   VG VolGroup00   lvm2 [68.34 GB / 0    free]
 PV /dev/md2    VG VolGroup00   lvm2 [66.25 GB / 64.00 MB free]
 Total: 2 [134.59 GB] / in use: 2 [134.59 GB] / in no VG: 0 [0   ]
[root@xen01 ~]# vgscan
 Reading all physical volumes.  This may take a while...
 Found volume group "VolGroup00" using metadata type lvm2
[root@xen01 ~]# lvscan

 ACTIVE            '/dev/VolGroup00/LogVolXen' [118.53 GB] inherit

sda1:sdb1 = boot (100MB)
sda2:sdb2 = swap (2048MB)
sda3:sdb3 = Lvm
sdc = Lvm

[root@xen01 boot]# lsmod | grep mpt
mptscsih               41469  0
mptbase                57757  1 mptscsih
scsi_mod              116429  3 sg,mptscsih,sd_mod

Does anyone have any suggestions on the steps I should take next to 
debug this?
Thanks everyone.
