REQRUNDOWN, Error accessing database xxxx. Must be rundown on cluster node yyyy.

Run Time Error: This indicates that GT.M could not open database file xxxx due to a prior improper shutdown on cluster node yyyy. A GT.M process on cluster node yyyy may have failed to attach a database memory segment or it was terminated by a method other than MUPIP STOP.

Action: If you are using before image journaling, perform a MUPIP JOURNAL RECOVER/ROLLBACK operation to address this issue. Otherwise, run the MUPIP RUNDOWN command from cluster node yyyy. If MUPIP RUNDOWN with no parameters does not work, specify the region name or file-specification with the qualifier REGION or FILE, respectively.
