Using COUP to Set Compression Mode (NonStop

Himalaya K-Series Servers)

Use the following procedure to set the compression mode of a 5190 tape drive using

COUP:

1. Stop all processes that are using the tape drive, and bring down the tape drive

using the PUP DOWN command. See Bringing Down a Cartridge Tape Drive on

page 4-34.

2. Use COUP commands to determine the current compression attribute of the drive,

stop the drive, alter the compression attribute of the drive, and restart the drive.

The following example sets compression on for a 5190 tape drive named $TAPE1.

(Entries shown in boldface show compression status before and after the ALTER

command was issued.)

3. Bring up the tape drive using the PUP UP command. See Bringing Up a Cartridge

Tape Drive on page 4-33.
