确认是两个节点
grid@dbserver2:/home/grid $olsnodes
dbserver1
dbserver2
查看集群模式
grid@dbserver2:/home/grid $asmcmd showclustermode
ASM cluster : Flex mode enabled - Direct Storage Access
grid@dbserver2:/home/grid $
检查asm配置
grid@dbserver2:/home/grid $srvctl config asm
ASM home:
Password file: +OCRDG/orapwASM
Backup of Password file: +OCRDG/orapwASM_backup
ASM listener: LISTENER
ASM instance count: 3
Cluster ASM listener: ASMNET1LSNR_ASM
修改命令介绍
grid@dbserver2:/home/grid $srvctl modify asm -h
Modifies the configuration for ASM.
Usage: srvctl modify asm {[-proxy -spfile ] | [-pwfile ] [-pwfilebackup ] [-listener ] [-count {|ALL}] [-spfile ]} [-force]
-proxy To modify the ADVM proxy instance configuration
-spfile Server parameter file path
-pwfile Password file path
-pwfilebackup Backup password file path
-listener Listener name
-count |ALL The number of instances or ALL to have instances on all nodes
-force Force modification (ignore dependencies)
-help Print usage
解决办法：
srvctl modify asm -count 2
看着顺眼了
