Step 5: Create the state database replicas

Step 6: Create the md.tab table entries

8.Enter: y

The partition> prompt returns.

9.Enter: partition> q

The format> prompt returns.

10. To select the next disk to be partitioned, enter: format> disk and return to item 2.

If you have finished partitioning all the new disks, enter: format> q and continue with the next step.

1.Alter your path by entering the following commands:

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

2.Create two state database replicas on slice 1 of boot disk 2:

#metadb -a -c3 -f /dev/rdsk/<device>

(where <device> is the target number of boot disk 2)

3.Verify that the replicas were created by entering the following command:

# metadb -i

The system lists the state database replicas currently on the system. The following sample output shows two replicas on c0t2:

	flags	first blk	block count
a	u	16	1034	/dev/dsk/c0t2d0s1
a	pc luo	16	1034	/dev/dsk/c0t2d0s1

Make sure the list includes the two replicas you just created.

1.Make copies of essential system files by entering these commands:

#cp /etc/opt/SUNWmd/md.tab /etc/opt/SUNWmd/md.tab.orig

#cp /etc/vfstab /etc/vfstab.orig

#cp /etc/system /etc/system.orig

2.Edit /etc/opt/SUNWmd/md.tab and insert entries for the root and /cms metadevices. If your system is running CMS load r3v6aj.c or later, you must also create a section for the swap metadevice.
