| Default: | none |
| Restriction: | An error is returned if you specify a value for this option that exceeds the maximum number of volumes for the unit. |
| Requirements: | To specify this option, you must first specify BULKLOAD=YES. |
| This option applies only to the input file (BL_DB2REC data set). This is the file that must be loaded into the DB2 table. | |
| Data source: | DB2 under z/OS |

specifies the number of volumes across which data sets can be extended. It must be an integer between 1 and 59. This option is ignored if the value is greater than 59. See the details in this section.
You must specify an integer from 1–59 as a value for this option. This option is ignored if the value is greater than 59. However, the value depends on the unit name in BL_DB2DEVT_PERM=. At the operating environment level an association exists that specifies the maximum number of volumes for a unit name. Ask your storage administrator for this number.
The data class determines whether SMS-managed data sets can be extended on multiple volumes. When you specify both BL_DB2DATACLAS= and BL_DB2UNITCOUNT=, BL_DB2UNITCOUNT= overrides the unit count values for the data class.
