kernel panic on a 2950

[Chamberland, Robert]

I have three PE 2950's with RHEL4 installed.  Two are identical in
hardware configuration - with hardware RAID 1/1 and acting as web
servers, the other is identical except it's in a RAID 1/5 setup with
differently sized disks acting as a DB server.  All were purchased at
roughly the same time.  All disks are SAS.  All are LVM'ed.  All have
been operating with no problems for about a year, getting their usual
up2dates, no major changes with LVM, fstab, etc. 

 

Recently, after messing with NIC configs repeatedly, I shut down one
machine from KDE.  When I brought the machine back up it kernel
panicked:

 

Uncompressing Linux...Ok, booting the kernel. 
ide0: I/O resource 0x3f6-0x3f6 not free. 
ide0: ports already in use, skipping probe 
Red Hat nash version 4.2.1.13 starting 
   Reading all physical volumes.  This may take a while... 
   No volume groups found 
   Volume group "VolGroup00" not found 
ERROR: /bin/lvm exited abnormally! (pid 480) 
mount: error 6 mounting ext3 
mount: error 2 mounting none 
switchroot: mount failed: 22 
umount /initrd/dev failed 2 
kernel panic - not syncing: Attempted to kill init!

 

The hardware RAID (ctrl-R) reports seeing the physical disks and reports
them as being in optimal condition.

 

Just before the RHEL rescue disk kicks in the controller correctly
reports seeing two logical drives.

 

The rescue disk reports not seeing the drives and asks if I want to
install drivers for them (which I skip).

 

The Redhat tech asked me to try lvm and fdisk from the rescue shell,
with these results:

 

lvm pvscan - No matching physical volumes found. 
lvm vgscan - No volume groups found. 
lvm lvscan - No volume groups found. 
lvm vgchange -ay - No volume groups found.

Fdisk -l (nothing happened)

 

Now the Redhat tech is saying the hardware must be incompatible with
RHEL4, which I doubt (since this came from Dell, which I assume means it
passed the HCL, and in any case has been up for a year with no
problems).

 

Any thoughts or suggestions, has anyone seen this before?  Is this a
Dell or Red Hat issue?
