Relocate a voting disk from ASM Diskgroup to a NFS shared file system and Vice Versa in 11g


##########################
## Objective
##########################

Relocate a voting disk from ASM Diskgroup to a NFS shared file system and Vice Versa in 11g

======================================================================================================================

Disk Group Where Voting Disk is now : +OCR_VOTE
New Voting disk location (NFS Mount Point ) : /u07/oracle

### Points to note

Voting Disk must be placed on shared devices; either on cluster filesystems, NFS or shared raw devices.

======================================================================================================================

Step  1 : Check the  Present Location of Voting disk
Step  2 : Relocate voting disk from ASM to NFS shared Mount point
Step  3 : Now Check the New Location of Voting disk
Step  4 : Backup of Voting Disk
Step  5 : Relocate the Vote disk back to ASM Disk group
Step  6 : Now Check the New Location of Voting disk

======================================================================================================================

======================================================================================================================
Step 1 :
--------
Check the  Present Location of Voting disk
======================================================================================================================

crsctl query css votedisk

+ASM1 @ hostd01:/u01/home/oracle
> crsctl query css votedisk
##  STATE    File Universal Id                File Name Disk group

 2. ONLINE   086dd7a7970e4f5dbf62d8760b8ab480 (/dev/mapper/ocr02p1) [OCR_VOTE]

Located 3 voting disk(s).
+ASM1 @ hostd01:/u01/home/oracle

======================================================================================================================
Step 2 :
--------
Relocate voting disk from ASM to NFS shared Mount point
======================================================================================================================

crsctl replace votedisk /u07/oracle/votedisk.dt


+ASM1 @ hostd01:/u07/oracle
> crsctl replace votedisk /u07/oracle/votedisk.dt
Now formatting voting disk: /u07/oracle/votedisk.dt.
CRS-4256: Updating the profile
Successful addition of voting disk 78e3c124a6f34f93bf2141cc31a97759.
Successful deletion of voting disk 19ac2decfd6c4f6ebf87cd9d247d7e7a.
Successful deletion of voting disk 086dd7a7970e4f5dbf62d8760b8ab480.
Successful deletion of voting disk 4a96ec03cee14f54bfa8835a98c5d31b.
CRS-4256: Updating the profile
CRS-4266: Voting file(s) successfully replaced
+ASM1 @ hostd01:/u07/oracle

Note : If you want to check the File system type, then in Linux use below command to find it.

df -T .

+ASM1 @ hostd01:/u07/oracle
> df -T .
Filesystem    Type   1K-blocks      Used Available Use% Mounted on

               nfs   637009920 400898560 236111360  63% /u07

======================================================================================================================
Step 3 :
--------
Now Check the New Location of Voting disk
======================================================================================================================

+ASM1 @ hostd01:/u07/oracle
> crsctl query css votedisk
##  STATE    File Universal Id                File Name Disk group

Located 1 voting disk(s).
+ASM1 @ hostd01:/u07/oracle

======================================================================================================================
Step 4 :
--------
Backup of Voting Disk ( We will take a backup of voting disk for safety purpose )
======================================================================================================================

dd if=/u07/oracle/votedisk.dt of=/u07/oracle/vd.bkp

+ASM1 @ hostd01:/u07/oracle
> dd if=/u07/oracle/votedisk.dt of=/u07/oracle/vd.bkp

-rw-r-----  1 oracle oinstall 21004800 Nov 29 03:15 votedisk.dt


======================================================================================================================
Step 5 :
--------
Relocate the Vote disk back to ASM Disk group
======================================================================================================================

crsctl replace votedisk +OCR_VOTE

+ASM1 @ hostd01:/u07/oracle
> crsctl replace votedisk +OCR_VOTE
CRS-4256: Updating the profile
Successful addition of voting disk 02b990acc2414f21bf4d483e72ccf1ec.

Successful addition of voting disk 0c28a49e64344f64bfe2ec1792305602.
Successful deletion of voting disk 78e3c124a6f34f93bf2141cc31a97759.
Successfully replaced voting disk group with +OCR_VOTE.
CRS-4256: Updating the profile
CRS-4266: Voting file(s) successfully replaced
