Re: Disk Issue

Generally these lbolt errors "can" indicate an impending disk failure. I would suggest that it's a good time to review your backup procedures. You might also want to see if you can get a replacement drive onsite so you will be ready.

Re: Disk Issue

Hi RKumar,

Error indicates that there is a issue to the disk path 0/1/1/1 which could be due to cable, terminator etc.. and it recovered after some time.

If this error appears only few times, you can check the disk integrity and ignore it. If the error repeats then there is some serious and you may need to check cable, terminator and replace the disk if needed.

Use this commands to check the disk integrity.

First find out the disk using this command.
#ll /dev/dsk |grep 0x03a000

check if any stale extends
#pvdisplay -v /dev/dsk/cxtxdx |grep stale

Try reading the disk to check disk integrity
#dd if=/dev/dsk/cxtxdx of=/dev/null bs=1024k

Hope this helps
Best wishes,

Ganesh.
