For more information:
• “SCF Object States” (page 62) describes the possible SCF states of tape drives and other
devices.
• The Guardian User’s Guide provides additional information about tape operations and
the tasks you can perform.
Example
To obtain status information about the tape drive $TAPE0 by using SCF:
> SCF STATUS TAPE $TAPE0

Monitoring Tape Drive Status With MEDIACOM
The MEDIACOM command STATUS TAPEDRIVE displays the current status of a tape drive. Among
other things, this command tells you whether a tape is mounted on the drive, the name of the
DEFINE associated with the tape, and which volume catalog and pool owns it.
NOTE: Manual unloading of a tape is not detected by a tape drive, so information from STATUS
TAPEDRIVE can be out of date. For example, STATUS TAPEDRIVE could report that a drive currently
has a tape mounted when the tape was removed from the drive by the operator before the command
executed.
To check the status of all tape drives on your system with MEDIACOM:
> MEDIACOM STATUS TAPEDRIVE
A listing similar to this one is sent to your home terminal:
MEDIACOM - T6028D42 (18DEC98)
