ORA-15077 Could Not Locate ASM Instance Serving A Required Diskgroup

vmware에서 오라클 RAC 구성 후 테스트 도중 vmware가 hang이 걸리며 뻗어 버림.

속 편하게 리부팅 한후 오라클 시작과 동시에 친절하게도 아래 메시지를 뿜어 주셨다. - _-;;

SQL> connect '/as sysdba'
Connected to an idle instance.
SQL> startup
ORA-01078: failure in processing system parameters
ORA-01565: error in identifying file '+DG1/devdb/spfiledevdb.ora'
ORA-17503: ksfdopn:2 Failed to open file +DG1/devdb/spfiledevdb.ora
ORA-15077: could not locate ASM instance serving a required diskgroup

metalink 에서 관련 코드로 검색해보다 비슷한 예문 발견,

Diskgroup were not mounted on the second ASM instance

GROUP_NUMBER  NAME         STATE TYPE TOTAL_MB FREE_MB 
0             DG1          DISMOUNTED 0        0
0             RECOVERYDEST DISMOUNTED 0        0

export ORACLE_SID=+ASM1
sqlplus '/as sysdba'
startup
ASM instance started

Total System started

이후 정상적으로 오라클 올라 왔음. ㅋㅋ
