DSNB221I   csect-name-BUFFER MANAGER TABLESPACE/INDEXSPACE CLEAN-UP PROCESS WAS NOT REQUIRED FOR PSID = X'psid'

This message indicates that the buffer manager (BM) table space or index space cleanup process was bypassed for the associated table space or index space. After quiescing all other activities against the table space or index space, the buffer manager discovered that the table space or index space is no longer in active mode; that is, it was closed.

The abnormal condition detected earlier was resolved by buffer manager close page set processing. Refer to the corresponding message, DSNB209I, using psid as the matching field, for the reasons the buffer manager schedules the table space or index space cleanup process. The psid is the internal identifier for the associated table space or index space.
