K460 / 11.0 / stale extents

After mirroring the new disk, we found some stale extents.

output below:

root:#
> do
> echo $i
> lvdisplay -v $i |grep -i "stale"
> done

/dev/vg00/lvol1
LV Status available/stale
00019 /dev/dsk/c0t6d0 00019 current /dev/dsk/c0t4d0 00019 stale
/dev/vg00/lvol2
/dev/vg00/lvol3
/dev/vg00/lvol4
/dev/vg00/lvol5
/dev/vg00/lvol6
/dev/vg00/lvol7
LV Status available/stale
00000 /dev/dsk/c0t6d0 01345 current /dev/dsk/c0t4d0 01452 stale

LV Status available/stale
00004 /dev/dsk/c0t6d0 01477 current /dev/dsk/c0t4d0 01584 stale
/dev/vg00/swap02

diskinfo comes back fine on both disks
dd comes back fine on c0t4d0 that shows the stale extents.

booting from the mirror disk crashes at activating volume groups.

dd on c0t6d0 took too long that our maintenance window expired and we had to kill it.

thank you in advance

i suspect c0t4d0 might have problem. Check

# dmesg
# more /var/adm/syslog/syslog.log

And look for "lbolt scsi" errors. If there are, it might indicate the disk is failing soon.

To confirm disk status, check them thru online Diagnostic tools (stm/cstm/xstm). If you don't have this, you can download them from software.hp.com. Look for onlineDiag.

# cstm

View all devices
cstm > map

Eg. disk device at number 20
cstm > sel dev 20
cstm > information; wait
cstm > infolog

Result will be displayed shortly and look for media/write/read errors. If the value is more than 0. Replace the disk.

Please assign some points if this answer your question, thanks!
