How to Add/Remove Votedisk file in oracle 11g Cluster:

Adding Votedisk:

Get the existing Vote Disks associated into the cluster. To be safe, Bring crs cluster stack down on all the nodes
but one on which you are going to add votedisk from.

(1) Stop CRS on all the nodes in cluster but one.

[root@node2-pub ~]# crsctl stop crs

(2) Get the list of Existing Vote Disks

crsctl query css votedisk

[root@node1-pub ~]# crsctl query css votedisk
0. 0 /u02/ocfs2/vote/VDFile_0
1. 0 /u02/ocfs2/vote/VDFile_1
2. 0 /u02/ocfs2/vote/VDFile_2
Located 3 voting disk(s).

(3) Backup the VoteDisk file

Backup the existing votedisks as below as oracle:

dd if=/u02/ocfs2/vote/VDFile_0 of=$ORACLE_BASE/bkp/vd/VDFile_0

[root@node1-pub ~]# su - oracle
[oracle@node1-pub ~]$ dd if=/u02/ocfs2/vote/VDFile_0 of=$ORACLE_BASE/bkp/vd/VDFile_0
41024+0 records in
41024+0 records out
[oracle@node1-pub ~]$

(4) Add an Extra Votedisk into the Cluster:

If it is a OCFS, then touch the file as oracle. On raw devices, initialize the raw devices using "dd" command

touch /u02/ocfs2/vote/VDFile_3 <<-- as oracle
crsctl add css votedisk /u02/ocfs2/vote/VDFile_3 <<-- as oracle
crsctl query css votedisks

[root@node1-pub ~]# su - oracle
[oracle@node1-pub ~]$ touch /u02/ocfs2/vote/VDFile_3
[oracle@node1-pub ~]$ crsctl add css votedisk /u02/ocfs2/vote/VDFile_3
Now formatting voting disk: /u02/ocfs2/vote/VDFile_3.
Successful addition of voting disk /u02/ocfs2/vote/VDFile_3.

(5) Confirm that the file has been added successfully:

[root@node1-pub ~]# ls -l /u02/ocfs2/vote/VDFile_3
-rw-r----- 1 oracle oinstall 21004288 Oct 6 16:31 /u02/ocfs2/vote/VDFile_3

3. 0 /u02/ocfs2/vote/VDFile_3
Located 4 voting disk(s).
