Hi Seenivasan,

#ioscan -funC disk
#diskinfo
#vgdisplay -v
#vgchange -a y vgname
#pvdisplay -v
#look at /var/adm/syslog/syslog.log to find any io errors with dev number and match this with the disk minor number under /dev/*dsk
#dd if=devicefile of=/dev/null bs=1024k
#stm
#dmesg

Addition to above (they are good examples),
You can also check this way;

echo 2400?20X | adb /dev/dsk/cxtyd0

Command output should be as follows (if there are no disk errors).

2400: 44454645 43543031 0 0
0 0 0 0
0 0 0 0
0 0 0 0
0 0 0 0

Those counters indicate of BBDIR that BadBlockDirectory any Bad Sector occurs in any disk , these numbers will be registered into these counters;
So, any non zero numbers indicate bad blocks and that disk should be changed on the spot !

Sreenivasan,

Look for LBOLT errors in syslog files, this identifies a failed disk at the same time your LVM commands outputs will also show PV status as unavailable. Do assign points !!
