Recently we had a power outage in our lab which caused all the Linux servers running Oracle database, switches, storage to go down. When the power was restored the servers, storages, and switches were brought up cleanly.
I noticed that Oracle ASM instance was down, so I tried to manually start it and got the ORA-01078 and ORA-29701 error messages.
Tried to use crsctl to start all the Oracle resources
On the Linux server running Oracle
When I looked at the owner and group of the disks, I noticed that the they had changed to owner root and group disk. No wonder Oracle is not seeing them.
Changed the owner and group of the volumes to oracle and dba
When I brought up asmca. I saw that the my +DATA diskgroup could now be seen, but was not mounted. I mounted the diskgroup, and everything worked fine after that.
