Database Software

Hi,

We are having 3 node cluster, DB is up and running fine on 2 nodes but for the third node it is showing disks are missing, But all the disks are present, still we are not able to mount the diskgroup and start the instance.

I am getting following error-


ERROR: diskgroup PODBPR06DATA was not mounted
