Problem:
After the accidentally deletion of the diskgroup DATA the Oracle cluster stack does not start on any node. The Oracle Cluster Registry (OCR) and voting disks are lost. The article shows how to recover them both.
[root@rac2 ~]# ocrcheck
PROT-602: Failed to retrieve data from the cluster registry
PROC-26: Error while accessing the physical storage ASM error [[clsuSlosFormatDiag called with non-error slos.]
] [0]
[root@rac2 ~]# crsctl query css votedisk
Located 0 voting disk(s).
