Check the alert log for ASM instance and check if maybe two of the devices went offline or had some type of issue. It is recommended that voting disk be from different arrays in the SAN to help with a possible array outage. You can even you two different San storage system and an NFS mount for the voting files that will give you the high redundancy from 3 physical location.

One thing I don't understand is that they do have redundancy on SAN so would this not being transparent to ASM? Thanks for help in advance.<br /><br />Anonymousnoreply@blogger.com
