| STEPS: 1) Check the current ASM diskgroup size: |
| select name,total_mb,free_mb from v$asm_diskgroup; |
| 2) Check the HEADER_STATUS shows as CANDIDATE or PROVISIONED for the ASM disks: |
| select group_number,disk_number,header_status,STATE,OS_MB,TOTAL_MB,FREE_MB,NAME,LABEL,PATH,VOTING_FILE from v$asm_disk order by GROUP_NUMBER,DISK_NUMBER; |
| 3) Check the raw disk path and diskgroup name and status |
| col PATH format a10; col name format a10; SELECT MOUNT_STATUS,HEADER_STATUS,MODE_STATUS,STATE,TOTAL_MB, FREE_MB,NAME,PATH,LABEL FROM V$ASM_DISK; |
| 4) Adding the disks to existing diskgroup online |
| ALTER DISKGROUP DG08 ADD DISK '/dev/oracleasm/disks/DG09' NAME DG09_0000; |
| 5) Post check status of diskgroup and HEADER STATUS as 'MEMBER' |
| col PATH format a10; col name format a10; SELECT MOUNT_STATUS,HEADER_STATUS,MODE_STATUS,STATE,TOTAL_MB, FREE_MB,NAME,PATH,LABEL FROM V$ASM_DISK; |
| 6) Check the diskgroup status and size in both nodes |
