Step 2: Identify the submirrors

1.Add the Solstice DiskSuite directories to your path:

#export PATH=$PATH:/usr/opt/SUNWmd/sbin:/olds

2.Enter a metastat command:

#metastat

3.Scan the output of the metastat command to find the name of the faulty disk. The following lines, for example, indicate that the faulty c0t2d0 disk is in d20:

#metastat

.
.
d20: Submirror of d21
Size: 14960160 blocks
Stripe 0:
Device	Start Block		Dbase	State	Hot Spare
c0t2d0s1	0		No	Okay
Stripe 1:
Device	Start Block		Dbase	State	Hot Spare
c0t4d0s3		0		No	Okay
.
.

Be sure to check all the submirrors. If the disk is also listed under d11 or d12, it is a boot disk belonging to two different submirrors. Replacing a boot disk involves some special considerations; those considerations are noted in this procedure where they apply.

4.Record below the metadevices to which the disk belongs (for example, d11 and d19):
