oracle删除DG磁盘组,CRS-2730集群资源DG无法删除
数据库集群资源状态不正常，数据库sqlplus可正常启动，
但是集群资源ora.db_name.db 状态是offline，
且客户端无法通过scanip连接数据库
[root@dbn02 bin]# ./crs_stat -t -v

之前已经在数据库级别把ARCH磁盘组删除了，但是集群资源里还在，并且无法online db资源，报以下错误
[root@dbn02 bin]# ./srvctl start instance -d dbn -i dbn1
PRCR-1013 : Failed to start resource ora.dbn.db
PRCR-1064 : Failed to start resource ora.dbn.db on node dbn01
CRS-5017: The resource action "ora.ARCH.dg start" encountered the following error:
ORA-15032: not all alterations performed
ORA-15017: diskgroup "ARCH" cannot be mounted
ORA-15063: ASM discovered an insufficient number of disks for diskgroup "ARCH"
. For details refer to "(:CLSN00107:)" in "/u01/app/11.2.0/grid/log/dbn01/agent/crsd/oraag".
CRS-2674: Start of 'ora.ARCH.dg' on 'dbn01' failed
删除已经不存在的ARCH资源，报错
[root@dbn02 bin]# ./crsctl delete resource ora.ARCH.dg
CRS-2730: Resource 'ora.dbn.db' depends on resource 'ora.ARCH.dg'
CRS-4000: Command Delete failed, or completed with errors.
查看集群数据库配置，发现DISK GROUPS 里仍然为 DATA和ARCH
[root@dbn02 bin]# ./srvctl config database -d dbn
Database unique name: dbn
Database name: dbn
Oracle home: /u01/app/oracle/product/11.2.0/db_1

修改集群数据库资源配置
[root@dbn02 bin]# ./srvctl modify database -d dbn -a 'DATA'
查看配置，diskgroup 已经只剩余DATA磁盘组了
[root@dbn02 bin]# ./srvctl config database -d dbn
Database unique name: dbn

重新执行删除命令，删除ARCH资源
[root@dbn02 bin]# ./crsctl delete resource ora.ARCH.dg
资源已经删除
[root@dbn02 bin]# ./crs_stat -t -v
