A note[edit]
Just a quick note to say that if you are replacing a failed disk with Sol9/10 and disk suite, you should detach and clear any submirrors on the disk that are not in 'needs maintenance state', otherwise disksuite will get in a mess wrt the serial numbers on the disks at some point in the future.
Replace A disk[edit]
If a disk has gone down and been replaced with a new one...
the broken disk status would like this:
# metastat d90
d90: Mirror
Submirror 0: d91
State: Needs maintenance
Submirror 1: d92
State: Okay
Pass: 1
Read option: roundrobin (default)
Write option: parallel (default)
Size: 430007232 blocks
d91: Submirror of d90
State: Needs maintenance
Invoke: metareplace d90 c3t10d0s0 <new device>
Size: 430007232 blocks
Stripe 0: (interlace: 2048 blocks)
Device Start Block Dbase State Hot Spare
c3t8d0s0 0 No Okay
c3t9d0s0 0 No Okay
c3t10d0s0 0 No Maintenance
d92: Submirror of d90
State: Okay

Device Start Block Dbase State Hot Spare
c4t8d0s0 0 No Okay
c4t9d0s0 0 No Okay
c4t10d0s0 0 No Okay
You should also check the metadb placement, eg:
# usr/sbin/metadb
flags first blk block count
a m p luo 16 8192 /dev/dsk/c1t0d0s7
a p luo 8208 8192 /dev/dsk/c1t0d0s7
a p luo 16400 8192 /dev/dsk/c1t0d0s7
a p luo 16 8192 /dev/dsk/c1t1d0s7
a p luo 8208 8192 /dev/dsk/c1t1d0s7
a p luo 16400 8192 /dev/dsk/c1t1d0s7
There should be 3 copies of the metadb on each disk ideally, the flags will be different on a failing disk (if the disk is totally failing), use 'metadb -i' to see descriptions.
Remove metadb's on the faulty disk before removing the disk, eg.
# metadb -d /dev/dsk/c1t1d0s7
Installing the new Disk[edit]
label the disk[edit]
use format to label the disk
partition the disk[edit]
# prtvtoc /dev/rdsk/c3t10d0s2
this show the current partitions
you can copy the structure form a similar disk ie:
# prtvtoc /dev/rdsk/c4t10d0s2 | fmthard -s - /dev/rdsk/c3t10d0s2
check the new structure
# prtvtoc /dev/rdsk/c3t10d0s2

7 0 00 0 10176 10175
Enable the new disk[edit]
# metareplace -e d90 c3t10d0s0 d90: device c3t10d0s0 is enabled
If metadb replicas already existed on the disk then replace them eg.
# metadb -a -c 3 /dev/dsk/c1t1d0s0
check the status[edit]
the rebuild could take some time
# metastat d90
