Disk Media error

Hi All,

It looks there was an error reported on Compaq disk which is root disk(disk 1 1/0/1/1/0.6.0 sdisk CLAIMED DEVICE COMPAQ BD14689BB9
/dev/dsk/c4t6d0 /dev/dsk/c4t6d0s2 /dev/rdsk/c4t6d0 /dev/rdsk/c4t6d0s2
/dev/dsk/c4t6d0s1 /dev/dsk/c4t6d0s3 /dev/rdsk/c4t6d0s1 /dev/rdsk/c4t6d0s3)


But I don’t see any Read errors on the Cstm report but it reports 47 Non-medium errors
Please see below and let me know if i really have a disk problem.

Its current value is CRITICAL(5).

Event Time..........: Thu Aug 6 08:56:56 2009

Severity............: CRITICAL

Monitor.............: disk_em

Event #.............: 100337

System..............: veritas



Summary:

Disk at hardware path 1/0/1/1/0.6.0 : Media error





Description of Error:



The device was unsuccessful in reading data for the current I/O request

due to an error on the medium. The maximum number of retries were

attempted and the data could not be read.



Probable Cause / Recommended Action:



If the event is reported against a device other than a disk drive:



- Reformatting the medium may fix the problem.

- Alternatively, the medium in the device is flawed.

- If the medium is removable, replace the medium with a fresh one.

- Alternatively, if the medium is not removable, the device has

experienced a hardware failure. Repair or replace the device, as

necessary.



If the event is reported against a disk drive on a system on which none

or only some of the disks are in a redundant environment (i.e., mirrored):



- Review applications for errors at the time the event was reported to

determine which data could not be read.

- Attempt to re-read the data.

- Re-write the data to the disk to allow the disk to reallocate to a

spare area on the disk.

- If a re-read of the data and/or a rewrite of the data are not

successful, the disk should be replaced and data restored from backup.



If the event is reported against a disk drive on a system on which all

disks are in a redundant environment (i.e., mirrored):



- When the OS is patched to current LVM and SCSI patches, reallocation

will take place automatically for these disks, and no action needs be

taken to check or replace these drives.

- To avoid unnecessary paging and notification, the severity of this

event can be changed to MINOR_WARNING by enabling the alternate

configuration for this event in

/var/stm/config/tools/monitor/default_disk_em.clcfg (and

/var/stm/config/tools/monitor/rst_disk_em.clcfg, if it exists):



- Find the following lines:

EQ:100337:CRITICAL:...



and insert a "#" in column 1.



- Remove the "#" from column 1 of the line which starts:

EQ:100337:MINOR_WARNING:...

Re: Disk Media error

Open a call to hardware support. And you might need to replace the mirrored root disk.

Re: Disk Media error

Thanks to both of you, I have placed an order for new disk as this was an issue with HDD.

Re: Disk Media error

Hi Philemon,

You can use dd to find if any i/o errors on the disk. Use this command to read entire disk.

# dd if=/dev/rdsk/c4t6d0 of=/dev/null bs=1024k
Best wishes,

Ganesh.

Re: Disk Media error

You can also do a "dmesg" and your errors will show and you can always map the SCSI HW device to the I/O path.

CAn you post your dmesg output too?
