ORA-15137: The ASM cluster is in rolling patch state

之前解除安裝12.1的GI再安裝19.9的GI，在建立asmdisk的時候報錯：

ORA-15137: The ASM cluster is in rolling patch state.

Case 1. Update the patch level on all nodes, As root user

$ clscfg -patch

Example:

# <grid home>/bin/clscfg -patch
clscfg: -patch mode specified
clscfg: EXISTING configuration version 5 detected.
clscfg: version 5 is 12c Release 1.
Successfully accumulated necessary OCR keys.
Creating OCR keys for user 'root', privgrp 'root'..
Operation successful.

And validate as root user

$ crsctl query crs softwarepatch

Example:

# <grid home>/bin/crsctl query crs softwarepatch
Oracle Clusterware patch level on node host01 is [1964077727].

# <grid home>/bin/crsctl query crs softwarepatch
Oracle Clusterware patch level on node host02 is [1964077727].

If both were at same level,stop rolling patch mode from one of the node as root user

$ crsctl stop rollingpatch

Then startup the cluster and create asm diskgroup.

Example:

# <grid home>/bin/crsctl stop rollingpatch
CRS-1161: The cluster was successfully patched to patch level [1964077727].

Case 2. Apply the same patch on other node, then proceed to drop/create diskgroup.
