OCR / Vote disk Maintenance Operations: (ADD/REMOVE/REPLACE/MOVE) (Doc ID 428681.1)

For 11gR2 release

From 11.2, votedisk can be stored on either ASM diskgroup or cluster file systems. The following commands can only be executed when Grid Infrastructure is running. As grid user:

1. To add a Voting Disk
a. When votedisk is on cluster file system:

$ crsctl add css votedisk <cluster_fs/filename>
b. When votedisk is on ASM diskgroup, no add option available.
The number of votedisk is determined by the diskgroup redundancy. If more copies of votedisks are desired, one can move votedisk to a diskgroup with higher redundancy. See step 4.
If a votedisk is removed from a normal or high redundancy diskgroup for abnormal reason, it can be added back using:

alter diskgroup <vote diskgroup name> add disk '</path/name>' force;

2. To delete a Voting Disk
a. When votedisk is on cluster file system:

$ crsctl delete css votedisk <cluster_fs/filename>
or
$ crsctl delete css votedisk <vdiskGUID>     (vdiskGUID is the File Universal Id from 'crsctl query css votedisk')
b. When votedisk is on ASM, no delete option available, one can only replace the existing votedisk group with another ASM diskgroup

3. To move a Voting Disk on cluster file system

$ crsctl add css votedisk <new_cluster_fs/filename>
$ crsctl delete css votedisk <old_cluster_fs/filename>
or
$ crsctl delete css votedisk <vdiskGUID>
4. To move voting disk on ASM from one diskgroup to another diskgroup due to redundancy change or disk location change

$ crsctl replace votedisk <+diskgroup>|<vdisk>
Example here is moving from external redundancy +OCRVOTE diskgroup to normal redundancy +CRS diskgroup

1. create new diskgroup +CRS as desired

2. $ crsctl query css votedisk
