Harddisk status
i got the following in the syslog.log
# ----------------

# -------------------
i'm not sure whether the disk has failed or not
# ioscan --> s/w state CLAIMED
# pvdisplay --> PV State available
but the Event Monitoring Service is saying that the resource is down
I checked physically the disk leds and it looks normal.
NB: the disk has a mirrored copy
can you please help?

#!/bin/sh
##This script created for testing any stale extents in Lvol
##If in the output any stale extents are found,pls report directly to Unix admin
####################################################
##Uncomment the next line if debug mode needed
#set -x

for i in `bdf | awk '{ print $1}'| grep -v Filesystem`
do
lvdisplay -v $i > ~techsup1/if_any_stale
grep -i stale ~
val=`echo $?`
###echo $val
if [ $val -ne 1 ];then
echo "Logical Volume '$i' had stale volumes"
else
echo "Logical Volume $i OK"

rm ~
check in syslog of message "lbolt", do u find "recovered " in also there.

Re: Harddisk status
The EMS message indicates one of two things:
1) The disk has actually failed. This can be confirmed by dd if=/dev/dsk/c1t1d0 of=/dev/null bs=1024 count=10000 (use a real disk device) or cstm mstm xstm disk exercise function.
2) A hot swap disk has been removed from the system and put back in or switched, which results in an lbolt warning which stays around until either a reboot or a dmesg - or dmesg -c. One of those two commands is HP-UX, the other is Linux. I mix them up and usually end up trying both. They are harmless if done wrong.

Re: Harddisk status
see this error at your output
Disk at hardware path 0/1/1/0.1.0 : I/O request failed.
Disk at hardware path 0/1/1/0.1.0 : Media failure
I think there is a problem with disk
did you check with this things
1.ioscan
2.diskinfo
3.dd
Post output or this command
suppose your disk is /dev/dsk/c1t3d0
#ioscan -fnC disk
#diskinfo /dev/rdsk/c1t3d0
#dd if=/dev/rdsk/c1t3d0 of=/dev/null bs=1024k

Re: Harddisk status
#ioscan -fnC disk
and see the status . Please avoid the switch "u" and see the output.
