ROOT DISK STALE EXTENT ISSUE

[Neil Herring_1]

I have ONE stale extent on my root disk, as shown below:
00848 /dev/dsk/c0t6d0 00867 current /dev/dsk/c4t6d0 02734 stale
I have swapped out the root disk c4t6d0 and tried rebuilding it but the same stale extent was present which is strange.
We had an engineer out before who said that this could be a false error and we should swap out the primary root disk instead.
I just wanted to check if this was true as I guess that if it is then in fact the disk I have replaced c4t6d0 is now identical to the corrupt c0t6d0 and I need to put it back in quick?

Use diagnostics, diskinfo to check both disks. Here is some info - http://www.docs.hp.com/en/5991-1236/When_Good_Disks_Go_Bad.pdf

stale outstand means your disk has broke on some place. Beter is to replace the disk.

it most likely an hardware issue but it could be caused by a sw bug. COntact HP if they have this type of error logged with your current sw products installed and kernels

Hi Neil Herring,

Yup, the possibility that other disk (c0t6d0) having a problem is there. You need to check both disk by using 'dd' command :

# dd if=/dev/rdsk/c0t6d0 of=/dev/null bs=1024k
# dd if=/dev/rdsk/c4t6d0 of=/dev/null bs=1024k

If you saw the I/O error, that's the disk that you should replace.

Hope this information can help.

Cheers,
