Attached is the step for Solaris 8 , I have try on Solaris 10.
Solaris disksuite mirror
I just documented mine for Solaris 8. This is using Solstice Disk Suite. The drives are c1t0d0 and c1t1d0. Hope this helps.
Install Solstice disksuite from Solaris Software, disk 2 of 2.
#cd /cdrom/sol_8_202_sparc_2/Solaris_8/EA/products/DiskSuite_4.2.1
1. run ./installer
2. default install (place in /usr/sbin) and allow reboot
Run commands below:
# prtvtoc /dev/rdsk/c1t0d0s2 | fmthard -s - /dev/rdsk/c1t1d0s2
(This causes the mirrored disk to have the exact format as the main root disk).
Run format and check that BOTH internal disks match exactly. If not, this will fail.
BOTH internal drives need to match exactly.
# metadb -a -f c1t0d0s7

# metainit -f d26 1 1 c1t1d0s6
d26: Concat/Stripe is setup
# metainit d6 -m d16
d6: Mirror is setup
# echo “set md:mirrored_root_flag=1” >> /etc/system
edit /etc/vfstab. Use the /dev/md/dsk/d0 (or 1/3/4/5/6) instead of c1t0d0s0 (or 1/3/4/5/6)
reboot
run following commands:
# metattach d0 d20
d0: submirror d20 is attached
# metattach d1 d21
d1: submirror d21 is attached
# metattach d3 d23
d3: submirror d23 is attached
# metattach d4 d24
d4: submirror d24 is attached
# metattach d5 d25
d5: submirror d25 is attached
# metattach d6 d26
d6: submirror d25 is attached
Check progress of mirror sync. The mirroring takes 2-3 hours.
# metastat|grep -i progress
While waiting, run metastat -p | tee /etc/lvm/md.tab (captures DiskSuite config)
Then run # dumpadm -d /dev/md/dsk/d1

metaclear
metaclear(1M) System Administration Commands metaclear(1M)
NAME
metaclear - delete active metadevices and hot spare pools
SYNOPSIS
/usr/sbin/metaclear -h
/usr/sbin/metaclear [-s setname] -a [-f]
/usr/sbin/metaclear component
/usr/sbin/metaclear [-s setname] [-f] metadevice... hot_spare_pool...
/usr/sbin/metaclear [-s setname] -r [-f] metadevice... hot_spare_pool...
/usr/sbin/metaclear [-s setname] -p component
/usr/sbin/metaclear [-s setname] -p metadevice
DESCRIPTION
The metaclear command deletes the specified metadevice or hot_spare_pool., or purges all soft partitions from the designated component.
Once a metadevice or hot spare pool is deleted, it must be re-created using metainit before it can be used again.
Any metadevice currently in use (open) cannot be deleted.
OPTIONS
Root privileges are required for all of the following options except -h.
-a Deletes all metadevices and configured hot spare pools in the set named by -s, or the local set by default.
-f Deletes (forcibly) a metadevice that contains a subcomponent in an error state.
-h Displays usage message.
-p Deletes (purges) all soft partitions from the specified metadevice or component.
-r Recursively deletes specified metadevices and hot spare pools, but does not delete metadevices on which others
depend.
-s setname Specifies the name of the diskset on which metaclear will work. Using the -s option causes the command to perform
its administrative function within the specified diskset. Without this option, the command performs its function on
local metadevices and/or hot spare pools.
OPERANDS
metadevice ... Specifies the name(s) of the metadevice(s) to be deleted.
component Specifies the c*d*t*s* name(s) of the components containing soft partitions to be deleted.
hot_spare_pool ... Specifies the name(s) of the hot spare pools to be deleted in the form hspnnn, where nnn is a number in the range
000-999.
EXAMPLES
Example 1: Deleting Various Devices
The following example deletes a metadevice named d10.
# metaclear /dev/md/dsk/d10
The following example deletes all local metadevices and hot spare pools on the system.
# metaclear -a
The following example deletes a mirror, d20, with an submirror in an error state.
# metaclear -f d20
The following example deletes a hot spare pool, hsp001.
# metaclear hsp001
The following example deletes a soft partition, d23.
# metaclear d23
The following example purges all soft partitions on the slice c2t3d5s2 if those partitions are not being used by other metadevices or are
not open.
# metaclear -p c2t3d5s2
The following example purges soft partitions from a metadevice.
# metaclear -p d2
d3: Soft Partition is cleared
d4: Soft Partition is cleared
d5: Soft Partition is cleared
EXIT STATUS
