Intervention required

intervention.
Library manager check-1 condition
Indicates that the library manager has detected an unrecoverable condition
that does not allow continued execution of host requests, and will attempt to
re-initialize or switch to the standby library manager if the high availability
model is installed to correct the problem.
All storage cells full
Indicates that all of the customer storage cells in the library have cartridges
assigned to them.
Out of cleaner volumes
Indicates that a clean operation is required; however, there are no usable
cleaner volumes of the right media type in the tape library.
Note: This informational state is entered in a mixed tape drive system
(3490E/3590), if either type of cleaner cartridge is missing.
Dual write disabled
Indicates that the process that keeps the secondary database in sync with
the primary database is not running. This is normal if the second hard drive
feature that provides a secondary database is not installed.
Relationship between Operational Modes and States
When an operational mode or state change is requested, the library manager must
perform some steps before the change is completed. During this transition period,
the immediate mode or state of the tape library is
mode
or
state pending
. For
example, if the tape library is in the Online state and a request is made to enter the
Offline state, the immediate operational state is
Offline Pending.
The System
Summary window on the library manager console indicates whether the mode or
state is pending. Sometimes the change between the modes and the states occurs
quickly, and the pending status is displayed briefly.
Operational Mode Transitions
The library is only in one operational mode at any one time.
When a change in operational mode is requested from the library manager, a
pop-up window is displayed that allows the operator to confirm the mode change
request.
Note: This applies to the active library when the high availability model is installed.
Pause Mode to Auto Mode
A request to enter Auto mode can be performed by the operator using the operator
panel (see “Changing to Auto Mode” on page 76) or by using the library manager.
However the request is generated, the status of the 3494 is checked.
When a request to enter Auto mode is started using the library manager, the
following actions occur during the change from Pause mode to Auto mode:
