You can use the DB2BSDS keyword on the ANALYZE control statement to identify a DB2 bootstrap data set (BSDS).
Specify the fully qualified data set name. This name should refer to a VSAM key-sequenced data set (KSDS).
Do not specify the name of a BSDS archive copy, which is not a VSAM KSDS. BSDS cannot be a TAPE dataset.
Note:
