Hi Rohitrwx,

Q1)find the failed disk:-

Failed disk information automatically update in log file
with physical path
then run below commands
#format :here we can see like "" Drive not available""
#cfgadm -al
#iostat -en
With these commands we can find disks status.

Q-2) Repalce the failed disks.

If you create non-availablity raid on the disk,No need to
disk replacement
if the disk you using in Availability volume like :
-->RAID-1: first we need to remove plex which is on failed
disk. and recreate plex on newdisk.

-->RAID-5 :Spare disk will palce,
Now we need repalce the failed disk
#vxdiskadm
Select-- 4
Select -- 5
the failed disk will replace
--------------
remove failed disk from veritas

#vxdiskunsetup -C diskpath

Thanks
