This section provides instructions for removing the quorum disk configuration, if you implemented the feature and you decide you would like to remove it for any reason.
To remove the quorum disk configuration:
$GI_HOME/bin/asmcmd lsdg
If there is not at least one normal redundancy disk group, create one. Refer to My Oracle Support note 438580.1 for details on how to change disk group redundancy.
$GI_HOME/bin/crsctl replace votedisk +normal_redundancy_diskgroup
Run the following command for each quorum disk:
SQL> alter diskgroup diskgroup_name drop quorum disk quorum_disk_name force;
Wait for the rebalance operation to complete. You can tell it is complete when v$asm_operation returns no rows for the disk group.
Run the following command from each database node that has quorum disks in place:
/opt/oracle.SupportTools/quorumdiskmgr --delete --device [--asm-disk-group asm_disk_group] [--host-name host_name]
Run the following command from each database domain that has quorum disks in place:
/opt/oracle.SupportTools/quorumdiskmgr --delete --target [--asm-disk-group asm_disk_group]
Run the following command from each database domain that has quorum disks in place:
/opt/oracle.SupportTools/quorumdiskmgr --delete –config
