Did this so far
Hi,

Thanks for your suggestions. this is what i did until now as below

to check the configuration

Code:
# cfgadm -al
cfgadm: Configuration administration not supported

Any ideas which command should be used instead of cfgadm as some people suggested devfsadm which i havent used anytime. so then did below

Code:
#  drvconfig


After that i can see the c0t0d0 in format utility, which shows as the OS disk

Code:
  # format 
  c0t0d0 <SUN18G cyl 7506 alt 2 hd 19 sec 248>  OS disk
            /pci@1f,4000/scsi@3/sd@0,0


then i ran metareplace command with defective mirrors, as metastat output says "Invoke: metareplace d0 c0t0d0s0 <new device>"

Code:
  # metareplace –e d21 c0t0d0s4
  # metareplace –e d6 c0t0d0s3
  # metareplace –e d3 c0t0d0s1
  # metareplace –e d0 c0t0d0s0


From metastat output I can see that all the mirrors seems to be fine and are in sync with other sub mirrors and i can run prtvtoc as well...but the problem is if run metadb again it shows the "W" still exists as below. Some suggest to reboot which I don’t want to do now.

Code:
  # metadb
  flags first blk block count
  Wm p l 16 1034 /dev/dsk/c0t0d0s7
  a p luo 16 1034 /dev/dsk/c2t0d0s7
  a p luo 16 1034 /dev/dsk/c5t0d0s7
  a p luo 16 1034 /dev/dsk/c4t0d0s7
  a p luo 16 1034 /dev/dsk/c2t1d0s7
  a p luo 16 1034 /dev/dsk/c3t1d0s7
  a p luo 16 1034 /dev/dsk/c4t1d0s7
  a p luo 16 1034 /dev/dsk/c5t1d0s7

For this I have removed and re attached the database like below

Code:
  # metadb –d /dev/dsk/c0t0d0s7
  # metadb –a /dev/dsk/c0t0d0s7


Now when I check metadb output the errors are gone but some flags are missing (m – master, and p,l,o will only appear when rebooted as said in some forums) and came to know those will reappear once reboot is done which don’t want to do now.

Code:
  # metadb -i
          flags           first blk       block count
       a        u         16              1034            /dev/dsk/c0t0d0s7
       a    p  luo        16              1034            /dev/dsk/c2t0d0s7
       a    p  luo        16              1034            /dev/dsk/c5t0d0s7
       a    p  luo        16              1034            /dev/dsk/c4t0d0s7
       a    p  luo        16              1034            /dev/dsk/c2t1d0s7
       a    p  luo        16              1034            /dev/dsk/c3t1d0s7
       a    p  luo        16              1034            /dev/dsk/c4t1d0s7
       a    p  luo        16              1034            /dev/dsk/c5t1d0s7


Any suggestion on this and how it is done ?

Thanks in advance
