CLN Command—Clean Volume

Use the CLN command to update the volume cleaning date to today's date. This command also increments the cleaning count (adds one to the number of times a tape has been cleaned) and sets the number of temporary write errors and use count fields back to zero.

This command has the following format:

CLN volser, volser [-volser]
volser

Specifies the volume serial numbers of one or more tapes that have been cleaned. Code a space or a comma between VSNs. Code as many VSNs as you want, as long as you end before position 72.

-volser

(Optional) Specify ranges of VSNs that have been cleaned. Limit each range to 100 VSNs. The first number of the range must be lower than the second number. Code as many ranges as you want, ending before position 72. You may code both ranges and individual VSNs on the same command, separated by spaces or commas.

Example: JCL for the CLN Command
