Submirror 1: d4
State: Okay

d4: Submirror of d5
State: Okay
Size: 8392072 blocks
Stripe 0:
Device Start Block Dbase State Hot Spare
c3t1d0s0 0 No Okay

The status was okay...I wanted to unmirror the root filesystem,so I
followed as below.

#metadetach d5 d3
d5: submirror d3 is detached

#metaroot /dev/dsk/c3t0d0s0

the changes were made to the /etc/vfstab and /etc/system.

however when i did a reboot,i got the following error....

Any help would be appreciated?



You detached the d3 submirror and then tried to make it the root drive? Not what I would have done. You could have detached the submirror d3 and the system would have been unmirrored. Then metaclear d3 to recover that slice.
