In 22.214.171.124, DBCA fails to register a MGMTDB with Oracle Grid Infrastructure will not treated as an error.
The issue occur during GI upgrade MGMTDB is created by default in disk group for OCR/Voting disk group. Occasionally, the creation of MGMTDB fails due to insufficient disk space in OCR/Voting disk group.
A workaround is creating the MGMTDB in different disk group other than OCR/Voting disk group using dbca, but dbca does not report an error if registration of the MGMTDB resource to OCR fails. The example below shows "how to create MGMTDB manually using dbca". The output shows successful creation of MGMTDB, and dbca reports no error. However, "crsctl stat res -t" does not show the MGMTDB resource.
