Operating in Manual Mode
Performing Manual Mounts–Host Software Component
The following pages describe how to perform manual mounts in an LSM that is
offline. These procedures apply only to an ACS that is running under the host
software component (HSC) version of the Nearline software.
If your ACS is running under a non-host software component version, contact
your systems administrator for manual mount information.
Resetting the Transport Display
Note: Only the 4480/4490 drives require resetting of the transport display.
At the beginning of manual mode operation, each 4480/4490 transport is in a
HOLD OFF LOAD condition. In this condition, the message display panel above
the transport is blank and the transport does not load if a cartridge is mounted.
This condition must be cleared before you mount cartridges manually.
Figure 3-21 on page 3-30 shows the locations of the 4480/4490 switches and
message display panel. To reactivate the transport display and clear the HOLD
OFF LOAD condition:
Note: Do not enter the LSM until you are familiar with the procedure described
in “Entering the LSM” on page 3-17.
1. If the transport contains an unloaded cartridge, remove it from the transport
and the LSM.
Do not place it in an empty storage cell in the LSM. It must be entered
through the CAP for the LSM to properly catalog it.
2. With the transport empty and the
READY indicator on, hold down the
REWIND and UNLOAD switches simultaneously for about 4 seconds.
WARNING:
BODILY INJURY. Empty transports perform elevator motions if the
control unit is powered off and then powered on. KEEP FINGERS AWAY
FROM TRANSPORT OPENINGS UNTIL TRANSPORT DISPLAY IS
ACTIVATED.
3. If the
READY indicator is off:
• Press the
READY switch.
• Hold down the
REWIND and UNLOAD switches at the same time.
The transport display must be activated and the HOLD OFF LOAD
condition cleared for each nonbusy transport that does not have an active
display.
Note: Allocated transports display the cartridge volume serial number and
the cell location. An asterisk is displayed if the transport is not
allocated to a mount request.
