So adding three more disks , each disk to each failgroup

New disks
/dev/oracleasm/disks/OCRVD_NEW1
/dev/oracleasm/disks/OCRVD_NEW2
/dev/oracleasm/disks/OCRVD_NEW3

Adding new disks
SQL> alter diskgroup VOTEDISK add
failgroup VOTE1 disk '/dev/oracleasm/disks/OCRVD_NEW1'
failgroup VOTE2 disk '/dev/oracleasm/disks/OCRVD_NEW2'
failgroup VOTE3 disk '/dev/oracleasm/disks/OCRVD_NEW3' rebalance power 6; 2 3 4
Diskgroup altered.
check if the rebalance got completed. select * from v$asm_operation;
Checking if the old disks and new disks are visible in v$asm_disk
NAME PATH FAILGROUP STATE

VOTEDISK_0005 /dev/oracleasm/disks/ASMLIB2 VOTE3 NORMAL
VOTEDISK_0001 /dev/oracleasm/disks/ASMLIB3 VOTE1 NORMAL

VOTEDISK_0004 /dev/oracleasm/disks/ASMLIB4 VOTE2 NORMAL
VOTEDISK_0002 /dev/oracleasm/disks/OCRVD_NEW2 VOTE2 NORMAL
6 rows selected.

Drop the old disks
alter diskgroup votedisk drop disk VOTEDISK_0001,VOTEDISK_0005,VOTEDISK_0004 rebalance power 6;
check v$asm_operation;
Once the rebalance is done , query the below command in all the nodes to check if the new disks are listing as Voting disks
[oragrid@node1 ~]$ crsctl query css votedisk
