How to repalce a failed disk?..

Answer / priya

Check the status of the disks using command: iostat -e
or if the disk is a metadevice then use metastat -p

If the disk is faulty and needs to be removed then use the
prtvtoc /dev/rdsk/c#t#d#s2 > /diskprtvtoc to save the disk
partition.

Use the command cfgadm -c unconfigure c1::dsk/c1t1do to
unconfigure the device
verify using cfgadm -al if the disk is unconfigured

remove the failed disk using command cfgadm -x
remove_device c1::/dsk/c1t1do

run devfsadm -C -c disk to invoke cleanup to remove device
pathsand unreferenced links
verify it ls -ld /dev/rdsk/c1t1dos2 this should return no
devices

it is safe to physically remove the disk n replace
cfgadm -x insert_device c1::/dsk/c1t1do

now configure it cfgadm -c configure c1::dsk/c1t1do

Run devfsadm and verify about the configured disk using ls -
ld command.

Run the fmthard -s /diskprtvtoc /dev/rdsk/c1t1d0s2 to copy
back the saved partitions to the new configured and
inserted disk
