"Examples of valid system files" on page
2. Enter the metadb command:
# metadb -a -c4 -f /dev/dsk/c0t0d0s1
# metadb -a -c3 -f /dev/dsk/c0t1d0s1
Sometimes replicas may have to be replaced. A replica can become
3
corrupted, for example, and in that case needs to be removed and then
recreated. The procedure to do that is as follows:
1. Remove all existing replicas with the following command:
# metadb -d -f /dev/dsk/c0t0d0s1
!
WARNING:
Do not reboot the system after removing replicas! With replicas gone,
the system may not boot!
2. Recreate two replicas on the same partition:
# metadb -d -c4 -f /dev/dsk/c0t0d0s1
