Step 4:
Figure out where your root submirror slices are. Hopefully they are s0
on both drives.
Edit the file /etc/opt/SUNWmd/md.tab and put in the following …
# root mirror
d10 1 1 /dev/dsk/c0t3d0s0
d0 -m d10
d20 1 1 /dev/dsk/c0t1d0s0
And then save this file. Don’t worry that the manual says you need to
type in /dev/md/dsk/d10 in the place of d10, you don’t need it.
Solstice DiskSuite is a really smart product and it generally knows that
d10 is a metadevice. So keep is short and sweet in the md.tab file.
[ This section is specific to x86 architecture – verify with the manual ]
Make sure that the second submirror slice is a bootable filesystem.
# installboot /usr/lib/fs/ufs/pboot /usr/lib/fs/ufs/bootblk /dev/rdsk/c0t1d0s0
Now initialize the mirror d0
# metainit d20
concat/stripe setup
# metainit -f d10
concat/stripe setup
# metainit d0
mirror setup
………..and finally
# metaroot d0
If you check your /etc/vfstab file you will see a few changes …
Reboot with your newly mirror root filesystem.
