PRKZ-1125
Tried to list the configuration of MGMTDB, but it failed with PRKZ-1125.
[grid@primary01 ~]$ srvctl config mgmtdb
PRKZ-1125 : Oracle Grid Infrastructure Management Repository (GIMR) client is not configured.
PRKZ-1125 means that MGMTDB, also known as GIMR, is not been installed in the cluster, so it does not contain any configuration information. Possibly, you had removed MGMTDB previously.
