[[email protected] trace]# ps -ef | grep asm
root     206099 200334  0 11:17 pts/2    00:00:00 grep --color=auto asm

2. Cause analysis

ASM did not actually start successfully and could not locate the disk group.

3. Solution

Start the ASM instance manually. run as asm owner

sqlplus/as sysasm

startup

4. Root cause

In this version, ASM has the features of flex ASM. In this environment, the pattern used is flex.

[[email protected] ~]$  asmcmd
ASMCMD> showclustermode
ASM cluster : Flex mode enabled
ASMCMD> exit
[[email protected] ~]$ srvctl config asm
ASM home: <CRS home>
Password file: +OCR_VOTE/orapwASM
Backup of Password file: 
ASM listener: LISTENER
ASM instance count: 3
Cluster ASM listener: ASMNET1LSNR_ASM

When the ASM server in flex ASM starts, all ASM networks should be connected.

Check ASM listening

[[email protected] ~]$ lsnrctl status ASMNET1LSNR_ASM

The command completed successfully

You can see that the service is not registered in ASM listening.

Check whether the listening log is visible

111 and 112 access are denied. Combined with the CRS log on node 112, there is an ora-12547 error. Check the white list of sqlnet.ora and find that its address does not exist in the ACL.

You need to modify sqlnet.ora, add the corresponding address, and restart ASM listening to take effect.
