Which two steps must always be performed to delete node host04 from an Oracle 12c Clusterware cluster that
does not use Grid Naming Service (GNS)?
A.
Run the crsctl unpin css – host04 command as root on host01, or on either host02 or host03.
B.
Run the rootcrs.pl – delete –force command as root on host01, or on either host02 or host03.
C.
Run the rootcrs.pl – delete –force command as root on host04.
D.
Run the crsctl unpin css -n host04 command as root on host04
E.
Run the crsctl delete node -n host04 command as root on host04.
F.
Run the crsctl delete node -n host04 command as root on host01, or on either host02 or host03.
Explanation:
To delete a node from a cluster:
1. Ensure that Grid_home correctly specifies the full directory path for the Oracle Clusterware home on each
node, where Grid_home is the location of the installed Oracle Clusterware software.
2. (A) Run the following command as either root or the user that installed Oracle Clusterware to determine
whether the node you want to delete is active and whether it is pinned:
$ olsnodes -s –t
If the node is pinned, then run the crsctl unpin css command. Otherwise, proceed to the next step.
3. (F) From any node that you are not deleting, run the following command from the Grid_home/bin directory as
root to delete the node from the cluster:
# crsctl delete node -n node_to_be_deleted
