CER Command—Update Volume Certification Date

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

This command has the following format:

CER volser, volser... [-volser]

volser

Specifies the volume serial numbers of one or more tapes that have been certified. 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) Specifies ranges of VSNs that have been certified. 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.
