[SOLVED] Please assist with CentOS5.4 on HP ProLiant

Post by elliot_01 » 2009/11/16 16:09:23

Hi all,

I decided to change the box I was using for CentOS5.3 (64-bit) from a domestic HP solution to a ProLiant ML110 server.

Out of interest (and plain laziness) I decided to simply swap the hard drives hoping that CentOS would just detect the new hardware and sort itself out. From what I could tell, this indeed did happen initially, and I proceeded to run all the online updates (which seemed to also upgrade it to CentOS5.4). Unfortunately though I have had nothing but problems since, which I hope some of you kind folk can offer some advice with.

[b]1) SDA drives not being detected (re: http://tinyurl.com/yfcx565).[/b]
All the hard drives are being detected as hdx's instead of the correct sdx's. This was a known problem before I bought this server, but the posts I'd read all appeared to provide successful solutions.

Sadly they don't seem to be working for me. :-(

The solution I tried was to add the following lines to my grub.conf file:

ide0=noprobe
ide2=noprobe

One post also said "If you don't want to reinstall then make sure initrd contains the ata-piix driver...". I have no idea what this means, could anyone elaborate please?

I have tried other suggestions such as enabling the RAID facility within the BIOS, but this results in a kernel panic and lock-up.

[b]2) System Fan (re: http://tinyurl.com/yzydu94)[/b]
While searching for ways of forcing CentOS to detect the correct storage controller, I decided to update the Server's BIOS to the very latest. After doing this and rebooting, the system fan is now at full speed constantly. It's very loud! This is another know problem following the BIOS update, but again, the accepted solutions aren't working for me. :-( I tried falling back to the previous BIOS from the same HP support site, but this borked my system (well it seemed to dislike one of the 1TB drives) so, I decided to jump back to the latest BIOS. So I'm back with this, but with this turbine!

[b]3) Other(?) hardware not being detected.[/b]

"Cannot allocate resource regon 7 of 0000:00:01.0
Cannot allocate resource regon 7 of 0000:00:1c.0"

This appears during boot-up but I have no idea what they may be.

Is this happening becuase I simply transplanted the hard drive from a working system?

Is there a way of forcing CentOS to re-interrogate all the hardware for changes?

Thanks in advance for any help or advice.

Elliot

Do you have the previously installed 5.3 kernel you were using still listed in the grub menu? If so, attempt to boot into that kernel to see if you have any success.

Hi pjwelsh,

Thank you for taking the time to reply, it is most appreciated.

I have the following listed in my grub menu. I will try the older ones and report the results.

CentOS (2.6.18-164.6.1.el5)
CentOS (2.6.18-164.el5)
CentOS (2.6.18-128.7.1.el5)
CentOS (2.6.18-128.el5)

Cheers!

[url=https://www.centos.org/modules/newbb/viewtopic.php?viewmode=flat&topic_id=20848&forum=37]This thread[/url] seems like it might be relevant. Make sure your BIOS is not set to "legacy" PATA mode, rather to AHCI or SATA, not RAID, mode.

Hi pjwelsh,

I have now tried booting from the other kernels and the same problem exists regardless :-?

Very grateful for any further suggestions.

Thanks in advance.

Hi pschaff,

Thanks for the link.

CentOS bombs out during bootup with a 'kernel panic' UNLESS I set the BIOS to:

[b]SATA Native Mode Operation:[/b] Auto
[b]SATA RAID ENABLE:[/b] Disabled

To emphasize, if I set the above to anything else, CentOS does not boot :-o

This actually concurs with other posts I have read regarding this server though. Even in this mode, other owners have successfully got CentOS to detect the drives as sdx.

I find it rather disappointing that CentOS seems to support a domestic rig 'out-of-the-box' but not a classified server!

I should mention that the BIOS detects the drives correctly as SATA by the way, just CentOS that does not. Could the issue lie with this ata_piix module which I have read about in related threads? How exacly do I check that CentOS is 'using' it?

Thanks again for any further assistance.

Interesting update.

I have booted the server using a CentOS v5.4 LIVE CD and once to the desktop I checked the drive config to see all drives correctly detected as sdx's! Weird?!

Seems to me then, that I somehow need to force my existing installation to 're-scan' the hardware? Can anyone assist me with this please?

Thanks for reading.

CentOS supports what Red Hat supports, actually a superset if you count centosplus.

I'd try booting from CentOS 5.4 installation media (CD#1 or DVD) in rescue mode. If the drives are detected, chroot and make a new initrd.
[code]
chroot /mnt/sysimage
cd /boot
mv initrd$(uname -r).img initrd$(uname -r)_old.img
mkinitrd initrd$(uname -r).img $(uname -r)
[/code]
The above will use the installer kernel version. If you want to use another version replace $(uname -r) with the version, e.g. 2.6.18-164.6.1.el5 for the latest.

Hi pschaff,

Thank you for the input as ever.

Since my last post I decided to bite the bullet and do a complete clean re-install. This appears to have worked perfectly. Running 'hdparm -tT' also confirms the drives are operating with massive improvement.

Cheers.
