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)

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.

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.
