SVM Failed disk replacement on Solaris

                     SVM Failed disk replacement on Solaris
             
1.Take backup below file output:-
  a.metastat -p
  b.metastat -t
  c.metadb -i
  d.echo|fromat
  e.iostat -En
  f.ifconfig -a
2.Identify the failed disk by following commands:-
   #iostat -en
    — - errors —
    s/w h/w trn tot device
     6 50 0 6 c1t2d0

    #echo|format
    Indentifying the logs(/var/adm/message) & dmesg
3.detach the failed disk submirror
   #metadetach d0 d20
4.clear the submirror -->metaclear d20
5.delete the statedata base replica of failed disk
   #metadb -d -f c1t2d0s3
6.Remove hard drive from the tree in the sequence
  Incase the SCSI/SAS disk
  #cfgadm -al--->c0::dsk/c1t2d0 disk connected configured unknown
  #cfgadm -c unconfigure c0::dsk/c1t2d0)--->c1::dsk/c1t2d0 disk connected unconfigured unknown
  #cfgadm -z remove_device c0::dsk/c1t2d0 (for data disk only)

  In case of FCAL Sun 280R, V880, V490, V880, V890
  command sequence to replace the disks
  #luxadm -e port
  #luxadm probe(to display paths)
  #luxadm remove_device_F /dev/rdsk/c#t#d#s2
  #devfsadm -v -Cc disk (where:C=cleans dir:c=specify disk)
  #luxadm insert_device (optional)
7.Remove the disk from server
8.Insert the new disk
9.Configure the new disk
  #cfgadm -c configure c1:dsk/c1t2d0

Verify the device connected in device tree.-->cfgadm -al
10.Check the status in server by applying:
   #echo|format or #iostat -en
   if not visible
   #devfsadm -C -C disks
     or
   #devfsadm -c configure
11.Check the vtoc table for root disk and replaced disk if not same do below
   prtvtoc /dev/rdsk/c1t2d1s2 |fmthard -s - /dev/rdsk/c1t2d0s2
12.create the statedata base on replaced disk
   metadb -afc 3 /dev/dsk/c1t2d0s3
13.Reattach the mirror and wait until all mirrors will sycned
   #metainit d2 1 1 c1t2d0s0
   #metatttach d5 d2
   #metastat -ac or metastat -t to check the sycning status
 
14.safe to run metadevadm command to update the new ID
   #metadevadm -u
   #metadevadm -u /dev/dsk/c1t2d0
