Step 6: Recreate the state database replicas

1.Recreate the primary boot disk replicas you removed earlier by entering the following command:

#metadb -a -c4 -f /dev/rdsk/devname

2.Recreate the secondary boot disk replicas you removed earlier by entering the following command:

#metadb -a -c3 -f /dev/rdsk/devname

3.Verify that the replicas were created:

#metadb -i

The system lists the state database replicas currently on the system. The following, for example, shows three replicas on c0t4:

	flags		first blk	block count
a m	p	luo	16	1034	/dev/dsk/c0t0d0s1
a	p	luo	1050	1034	/dev/dsk/c0t0d0s1
a	p	luo	2084	1034	/dev/dsk/c0t0d0s1
a	p	luo	3118	1034	/dev/dsk/c0t0d0s1
a	p	luo	16	1034	/dev/dsk/c1t4d0s1
a	p	luo	1050	1034	/dev/dsk/c1t4d0s1
a	p	luo	2084	1034	/dev/dsk/c1t4d0s1

In the above example, there are 4 replicas listed for the primary boot disk (c0t0d0s1), and 3 replicas listed on the secondary disk (c1t4d0s1)

!WARNING:

Do not try to reboot a system when there are fewer than two state database replicas.
