Hi,

How to unconfigure a faulty mirrored disk and then replace the disk with new one, then configure the new inserted disk and mirroring also, and also how to check which disk is corrupt and from disk OS is booting up Please elaborate in details.

Need more details
is this a solaris sparc server or x86? (Model?)
how was the disk mirrored?
What error are you getting while booting?

Its a Sparc machine.
I am not getting any error message while booting as the system is booting from root disk and the mirrored disk is failed i think. I want to know how to check failed disk and the system is booting from which disk.

This kind of goes back to a thread a bit ago about how it is mirrored.
If it's via raidctl then run the following commands

Code:

# raidctl
Controller: 0
        Volume:c0t0d0
        Disk: 0.0.0
        Disk: 0.1.0
(Substitute in the volume from the above command in the one below)
# raidctl -l c0t0d0
Volume                  Size    Stripe  Status   Cache  RAID
        Sub                     Size                    Level
                Disk
----------------------------------------------------------------
c0t0d0                  68.2G   N/A     OPTIMAL  OFF    RAID1
                0.0.0   68.2G           GOOD
                0.1.0   68.2G           GOOD

it should show failed if one has failed and you are using raidctl.

If you are running Veritas a 'vxdisk list' should show your failed disk

If you are running Disk Suite then 'metastat' should show you what has failed.

If you are doing a ZFS mirror then 'zpool status' should show the failure.

Normally the light on the drive turns orange if you check it.
