Oracle Database: VOTE Disk (Closed) / Not Available

In this blog I am going to discuss an issue which I faced during my maintenance on cluster. 
One of the votedisk became unavailable and was dropped from the system in my cluster.


crsctl will only show me 2 Vote disks

$ crsctl query css votedisk
##  STATE    File Universal Id                File Name Disk group
--  -----    -----------------                --------- ---------
 1. ONLINE   578049fd7bd34f51bfdf9cd7d2e02205 (/dev/oracleasm/disks/OCR_VOTE1) [OCR_VOTE]
 3. ONLINE   232d262659714f84bfbede64f662f566 (/dev/oracleasm/disks/OCR_VOTE2) [OCR_VOTE]

From V$asm_disk I try to see the status of disk. 

SQL> select mount_status, path, header_status, mode_status from V$asm_disk  where path like '%OCR_VOTE%'

MOUNT_S PATH                                     HEADER_STATU MODE_ST

CACHED  /dev/oracleasm/disks/OCR_VOTE3           MEMBER       ONLINE

CACHED  /dev/oracleasm/disks/OCR_VOTE1           MEMBER       ONLINE

Solution  - I add back the Disk to Diskgroup

SQL> alter diskgroup OCR_VOTE add disk '/dev/oracleasm/disks/OCR_VOTE2' force;

(Reference - 

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

and then I check the status again from v$asm_disk and crsctl

SQL> select mount_status, path, header_status, mode_status from V$asm_disk  where path like '%OCR_VOTE%' ;

MOUNT_S PATH                                     HEADER_STATU MODE_ST
