ARC0686I

Explanation
 While DFSMShsm was processing SMS-managed data
set dsname with the EXPIREBV command, it detected
that the active SMS configuration did not contain management class mgtclassname.
 If the message contains DELETED, data set dsname is
not currently cataloged; management class mgtclassname was
associated with the data set when the data set was last backed up.
If the message does not contain DELETED, data set dsname is
currently cataloged and associated with management class mgtclassname.

System action
 In either case, DFSMShsm cannot determine how to expire
the cataloged backup version(s) that may exist for the data set; no
such versions are expired.
 The EXPIREBV command continues with
any backup versions identified as uncataloged.

Programmer response
 After the EXPIREBV command completes, determine
the contents of the active configuration. If there are many such messages,
it may be that the wrong configuration was activated.
 If data
set dsname is DELETED, it may be that mgtclassname was
deleted from the SMS configuration after dsname was
backed up, then deleted. The management class can be redefined, at
least temporarily, to delete the backup versions using the EXPIREBV
command; or you can use the BDELETE command to delete specific versions.
