SCF Reference Manual for the Storage Subsystem (G06.28+, H06.05+, J06.03+)

Adding a Fibre Channel Tape Drive
To add a Fibre Channel tape device that is directly connected to an FCSA, you specify the
PORTNAME (WWN) and LUN of the tape device. This command adds a Fibre Channel tape
device to the system:
-> ADD TAPE $LTO3, SENDTO STORAGE, LOCATION (110,3,4) &
-> SAC 2, PORTNAME 210000E08B1755DC, LUN 0
Altering Tape Drive Attribute Values
The “ALTER TAPE Command” (page 241) alters the attributes of a tape drive in the system
configuration database. For a description of alterable tape attributes, see “ALTER TAPE Attributes”
(page 242).
Considerations for ALTER TAPE
• The process must be in the STOPPED state or not running before you can change its
configuration.
• Changes take effect when you restart the process.
• Changing the Values of Tape Drive Attributes
1. Stop the tape drive:
-> STOP $TAPE0
2. Verify the tape drive is in the STOPPED state:
-> STATUS $TAPE0
3. Change one or more attributes. For example:
-> ALTER $TAPE0, COMPRESSION OFF
4. Verify the change took place:
-> INFO $TAPE0, DETAIL
5. Start the tape drive:
-> START $TAPE0
When the START TAPE command finishes successfully, the tape drive is left in the STARTED
state.
Deleting a Tape Drive
The “DELETE TAPE Command” (page 252) removes a tape drive from the system configuration
database.
Considerations for DELETE TAPE
• Stop the tape drive before deleting it.
• If the DELETE TAPE command does not work, try using the RESET TAPE, FORCED command
and then issue the DELETE command.
• Example
1. Verify the tape drive is in the STOPPED state:
-> STATUS $TAPE0
2. Remove the tape drive from the system configuration database:
-> DELETE $TAPE0
3. Verify the tape drive is removed from the system configuration database:
-> INFO $TAPE0
