RedHat 4 Kernel reporting bad sectors on DL385

Hello,

I'm seeing the following Kernel error message for my Server (HP Proliant DL385) running RedHat 4:

--------------------- Kernel Begin ------------------------


WARNING: Kernel Errors Present
Error: Medium error --...: 17 Time(s)
Unrecovered read error -- (asc=0x11, as...: 17 Time(s)
Buffer I/O error on device hda, l...: 34 Time(s)
end_request: I/O error, dev hda, sector...: 17 Time(s)
hda: irq timeout: error=0xd0LastFailedSe...: 9 Time(s)
hda: media error (bad sector): er...: 17 Time(s)
hda: media error (bad sector): st...: 17 Time(s)

---------------------- Kernel End -------------------------

Apart from the obviouse (run fsck in rescue mode), are there any other tools I can run on the box that will put my mind at rest?

The Servers Internal Drives (72.G) are mirrored with the OS installed in a LVM Volume Group vg00, and all other LVM's are built on LUNS from a HP-EVA 6000.

Should I be worried, as some people are saying the Kernel can sometimes be misleading??

Shalom,

Nigel, the disk is bad, replace it.

fsck will not help.

Re: RedHat 4 Kernel reporting bad sectors on DL385

Note that the device is "hda", i.e. an IDE/ATA device. Most likely this is the CDROM drive of your server, as it is the only traditional IDE/ATA device in the server.

External SCSI and all SATA disks tend to use /dev/sd* names, and the SmartArray RAID is usually /dev/cciss/*.

Type "hdparm -i /dev/hda" to get some identification information about the drive. That should help to confirm that the drive is a CD-ROM drive.

As the CDROM drive of a DL385 server is a laptop-like "slim-line" drive, ensure that the disk is correctly placed on the hub in the drive tray.

Matti,

just checked the server and YES there was a CD in the CD-Drive bay. I was also confussed to why the Kernel was talking about HDA devices, as the first internal disk is known as /dev/sda etc.

The CD must have bad sectors on it? I dont understand why the CD-drive was being accesed other than at boot time???

Many thanks guys.
