Data LUN moved from disk group - unable to start ASM
ORACLE 11.2.0.3
RAC = 3 NODES

Our system admin accidentally removed the DATA lun(SAN) and the Database crashed. The system admin moved the removed lun to the original place but now oracle is complaining about unable to start ASM and cannot find OCR. We don't have backup for this database.
