Use the ADDDATASET TSO subcommand to manually define a data set on a volume to DFSMSrmm. The volume on which the data set resides must have either master or user status.

BLKCOUNT(number_of_blocks)

Specifies the number of data blocks used by the data set. The value corresponds to that recorded in the data set's End of File label. The minimum allowable decimal value is 0; the maximum allowable decimal value is 99999999. DFSMSrmm uses BLKCOUNT, together with BLKSIZE, to calculate the approximate size of the data set and the sum of all data set sizes to set the volume usage. If you do not use BLKCOUNT, DFSMSrmm cannot list the space used for the data set or volume when you request it. The default value is 0.

Note: The total block count cannot be set or changed by subcommand. It is set based on information recorded during CLOSE processing.

BLKSIZE(block_size)

Specifies the block size of the data set. The minimum allowable decimal value is 0; the maximum allowable decimal value is 999999. DFSMSrmm uses BLKSIZE together with BLKCOUNT to calculate the approximate size of the data set and the sum of all data set sizes to set the volume usage. If you do not use BLKSIZE, DFSMSrmm cannot report space usage. The default value is 0.
