IDC2892I INVALID ENTRY TYPE FOR A VSAM VOLUME DATA SET

Explanation
A virtual storage access method (VSAM) volume data
set name was specified on a DELETE command and either an entry type
other than CLUSTER was specified or the entry type in the catalog
is not a cluster.

System action
The system does not delete the entry. The remaining
entries, if any, are deleted.

System programmer response
If the error recurs and the program
is not in error, search problem reporting data bases for a fix for
the problem. If no fix exists, contact the IBM® Support Center. Provide the JCL and the SYSOUT
output for the job.

Programmer response
Specify the CLUSTER parameter or run a LISTCAT
against the catalog to verify the entry type. Correct the error. 
Run the job again.
