Look at me today this single node 12C RAC, suddenly feel that the disk group of OCR is called +dg_sys a little uncomfortable, want to change to +SYS_DG. The approach is to migrate the Ocr/votedisk/asm SPFile to an existing ASM, and then modify the disk group name and finally migrate to the new name Disk group (this process +DG_SYS-GT;+DATA-GT;+SYS_DG)Current operating conditions[Grid@xifenfei ~]$ crsctl sta

So far, the tragedy has been repeated. Recovery Process: (in fa
