Using SCF
•
The following example changes tape drive $TAPE1 so that its tape process runs
only at a low PIN and then checks to make sure that the change has taken place:
->ALTER TAPE $TAPE1, HIGHPIN OFF
->INFO TAPE $TAPE1, DETAIL
•
The following example specifies that a maximum of 32 concurrent file opens are
allowed for the tape drive $TAPE1:
->ALTER TAPE $TAPE1, NUMOPENERS 32
For more information on the ALTER and INFO commands, see the SCF Reference
Manual for the Storage Subsystem.
Example 3: Deleting a Tape Drive From the System
You use the SCF STOP TAPE and DELETE TAPE commands to remove a tape drive
from the system configuration database.
Before issuing the SCF STOP command, use the SCF STATUS command to verify that
the tape drive is in the STOPPED state. For example:
->STATUS TAPE $TAPE0
If the STATUS command shows that the tape drive is not in the STOPPED state, use
the SCF STOP command to place the tape drive in the STOPPED state. For example:
->STOP TAPE $TAPE0
The following example removes tape drive $TAPE0 from the system configuration:
->DELETE TAPE $TAPE0
Use the INFO command to verify that the tape drive has been removed from the
system:
->INFO $TAPE*
