The STATUS Command
This example STATUS display shows:
•
$TAPE is a 5194 tape drive.
•
The controller type for $TAPE is 3216, indicating a 3216 controller. If $TAPE were
attached to an MFC, the controller type would be 3681.
•
The unit number assigned to $TAPE when it was added to the system
configuration (using COUP or SYSGENR) was 5. The unit number must match the
device ID for the drive, which is set using the drive front panel. (See Checking and
Setting the Device ID on page 3-41.)
•
Compression mode is on, indicating that compression mode was on during the last
write operation. If the compression mode changes (as a result of a MEDIACOM
command, for example), this field does not reflect the change until after the next
write operation. A change in the compression mode is possible only with 5190
tape drives; the 5194 drive operates with compression mode on at all times.
•
The cartridge map shows the location and number of cartridges currently loaded in
the ACL cartridge magazine, which is helpful during unattended backups. The
example shows no cartridges in slots 1 through 7. Slot 1 is empty because the
cartridge is in the drive.
•
The state of the drive is Rewinding, Sense Key = 2, (Not Ready) Logical Unit not
ready. This indicates that the cartridge is rewinding in the drive and that it is not
ready to write or read data.
