Which two steps must always be performed to delete node host04 from an Oracle 12c Clusterware cluster that does not use grid Naming Service (GN5)? (Choose two.)
A.
Run the crsctl unpin css – host04 command as root on host01, or on either host02 or host03.
B.
Run the rootcrs.pl -deconfig -force command as root on host01, or on either host02 or host03.
C.
Run the rooccrs.pl -deconfig -force command as root on host04.
D.
Run the crsct1 unpin css – host04 command as root on host04.
E.
Run the crsct1 delete node -n host04 command as root on host04.
F.
Run the crsct1 delete node -n host04 command as root on host01, or on either host02 or host03.
B , D
No, B it can never be a possible answer…
rootcrs.pl -deconfig -force is use when you have configure GNS therefore it can be correct and also when you have configure GNS you will use this command to delete the host04 for example… not in the reminder nodes…
so No
Correct D,E
Never mind, complete wrong…
Yes, typo when no GNS
[root@host01]# crsctl unpin css -n host04
[root@host01]# crsctl delete node -n host04
If GNS then
[root@host01]# crsctl unpin css -n host04
[root@host04]# ./rootcrs.pl -delete -force
[root@host01]# crsctl delete node -n host04
Correct: A, F (D is correct too..)
A: node can be unpined locally or remotely:
root@solaris11-03:~# olsnodes -s -t
solaris11-03 Active Pinned
solaris11-04 Active Pinned
root@solaris11-03:~# crsctl unpin css -n solaris11-03
CRS-4667: Node solaris11-03 successfully unpinned.
root@solaris11-03:~# crsctl unpin css -n solaris11-04
CRS-4667: Node solaris11-04 successfully unpinned.
F: https://docs.oracle.com/database/121/CWADD/adddelclusterware.htm#CWADD90995
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
At exam I had the same answers:
“crsctl unpin css – host04” (without -n), so:
Wrong: A
Wrong: D
Wrong: E
Correct: F
Did you approve it?
Correct Answer is C & F
To delete a node:-
# rooccrs.pl -deconfig -force (on the node to be deleted)
# crsctl delete node -n host04 (From any one of the surviving node)
Agree !
the only issue with this is that it said “cluster that does not use grid Naming Service (GN5)”
so this is not necessary:
rooccrs.pl -deconfig -force
So in the exam if they request 2 answers I will go for A,F
I know that A is wrong crsctl unpin css – host04 (it does not have -n)
I’m really confused
Does “deleting node” means the same as “removing node”?
F is right – you can only delete node from the other node (TESTED)
If the node was not pinned and does not host any Oracle databases using Oracle Database 11g release 1 or earlier, then the node is automatically removed from the cluster when it is shut down. If the node was pinned or if it hosts a database instance from earlier releases, then explicit deletion is needed.
A & F, same question as 145
Deleting a node with the crsctl delete node command implicitly unpins the node.
