between its highlighted and non-highlighted color to provide a visual indication
that the 3494 is still in Pause Pending mode. The library manager also beeps
five times.
2. The System Summary window is updated to indicate that the operational mode
is Pause Pending.
3. The library manager instructs the cartridge accessor to move to its park location
after completing the operations in progress.
4. The library manager is notified that the cartridge accessor is in its park location.
5. The library manager removes power from the cartridge accessor.
6. The library manager enters Pause mode and sends an attention message to all
attached hosts indicating that the state of the library changed.
7. The Pause Pending window is removed, and the System Summary window
indicates that the operational mode is Pause and that power is off.
8. The Pause Mode window is displayed that instructs the operator to wait while
the cartridge accessor is being parked. If the cartridge accessor cannot be
parked or if the status of its power is unknown, the window includes this
information.
Pause Mode to Manual Mode
A request to enter Manual mode is initiated by an operator using the library
manager (see “Using Manual Mode” on page 227). No specific operations are
performed by the library manager during the change from Pause to Manual mode.
As Manual mode is entered, an attention message is sent to all attached hosts the
indicates the state of the library changed to Manual mode.
The operational status is changed to Manual. If the cartridge accessor cannot be
parked or if the status of its power is unknown, the pop-up window includes this
information.
Manual Mode to Pause Mode
A request to enter Pause mode must be performed by an operator using the library
manager. During the change to Pause mode, the following steps are performed:
1. Operations that were fetched from the operations queue, but not confirmed as
executed by the operator, are returned to the operations queue for execution
when the library returns to Auto mode.
2. The library manager enters Pause mode and sends an attention message to all
attached hosts indicating that the state of the library changed.
Auto Mode to Manual Mode
When an operator selects Manual mode while the 3494 is in Auto mode, the library
performs the operations required to move to Pause mode and then move to Manual
mode. All pop-up windows indicate that the 3494 is in Manual Pending even as it is
moving through Pause mode. Also, an attention message is only sent when Manual
mode is entered, not for the intermediate pause mode. During the change from Auto
to Manual mode, the following steps are performed:
1. A Manual Pending pop-up window is displayed indicating that the change to
Manual mode is in progress and that the cartridge accessor is being parked.
2. The System Summary window indicating that the operational mode is Manual
Pending.
