Bringing Down a Cartridge Tape Drive

The PUP DOWN command makes a tape drive inaccessible to user processes.

Successful completion of the DOWN command stops the device. You bring down a

tape drive when you need to:

•

Upgrade or perform maintenance on the drive

•

Physically remove the drive from the system (but the system is not yet

reconfigured)

You must be a super-group user to execute the PUP DOWN command.

Remember to stop all processes using the tape drive before you bring down the drive.

If a cartridge is loaded in the drive when you issue the DOWN command, it is unloaded

before the drive is brought down.

Example

To bring down (remove from operation) the tape drive named $TAPE1, enter the

following command:

> PUP DOWN $TAPE1

To check to make sure that $TAPE1 is actually down, enter the following command:

> PUP LISTDEV $TAPE1

•

A letter D in the STATE column of the PUP LISTDEV display indicates the tape

drive is in the DOWN state.

•

A blank in the STATE column of the PUP LISTDEV display indicates the tape drive

is in the UP state.

•

For a list of all the possible device states, see the Peripheral Utility Program (PUP)

Reference Manual.
