Problem with DL380 and RedHat seeing CDROM

Hi All,

We have successfully installed Redhat V4 AS Update 2 onto three new DL380 G4 servers. All three servers had Redhat loaded from CD's. However one of the servers once booted no longer sees the CD-ROM drive.

The only difference I can see is that during booting the two servers that see the CD-ROM have the following entry in the boot log.

ide0:BM-DMA at xxxxxxx, BIOS Settings: hda:DMA,hdb:pio

The server that fails to see the CD-ROM when booted has the following entry.

ide0:BM-DMA at xxxxxxx, BIOS Settings: hda:pio,hdb:pio

Can anyone assist me in tracking down the problem.

Shalom Ronnie,

It sounds like a hardware problem. Take a peek inside and make sure the drive is properly connected. Then call hardware if it stil does not work.

It should show up on the gui disk browser.

Re: Problem with DL380 and RedHat seeing CDROM

Can you boot directly from the CD-ROM? This is to check if the hardware device works properly. If you can boot from the CD-ROM, then the hardware is correct, if not, then "software" level troubleshooting should be done.

Hello,

The message shows that you have different BIOS settings for your IDE CD-ROM devices :

=> DMA is enable
=> DMA is disabled

Before any other hardware repair, make sure that BIOS settings are identical for both servers.

Good lcuk.
