It is a SCSI error. May be one of the disk having problem. Same type of error(s).

Shalom shridhar,

You have/had two physical paths to the same logical volume. For some time one of those pathes failed. You report that the resync is complete and this is no longer a problem.

Therefore the messages should stop.

if they continue, you still have a problem and need to look into why one of the paths is gone. Perhaps a scsi or fiber card or cable has failed.

Perhaps you need to manually resynch the PV.

Check the disk 1f055000.
The error 5 is i/o error. run lvdisplay/pvdisplay and dd tests to check disk.
Also check disk in stm.

The disk in question is c5t5d0

Hi,
Use this small command line scrip to find any more stale PE are there

#for i in ` vgdisplay -v|grep "LV Name"|awk '{print $3}'`
> do
> lvdisplay -v $i |grep stale
> done

You need to consult your hardware vendor to come and have a look at the system. Possible look at cable connectivity, scsi terminations, storage system health check etc..

Regards,
Sunil

You should really dd the drive....

dd if=/dev/rdsk/c5t5d0 of=/dev/null bs=64k

Let this run until completion... if you see an I/O error, the disk needs to be replaced. If it completes with no I/O error, disk media should be OK...

As stated earlier, it's also a good idea to take a look at stm logtool.
