Initialization complete
The tape library starts the library manager application and determines the
operational mode and state. The mode and state are based on the availability
conditions of the components and whether the 3494 is taught and inventoried. If the
3494is taught and inventoried, the library manager waits for one of the following
conditions:
vAn operator instruction to proceed to an operation mode and operational state.
vA time-out interval expires and causes the 3494 to go to the default operational
mode and operational state set by the availability conditions of the tape library
components.
Online State
In this state, the library manager accepts and processes host commands.
Offline State
In this state, the library manager does not accept or process host commands.
Commands received before entering the Offline state are processed.
Operations performed while the 3494 is in the Offline state, such as inventory,do
not report errors to the host. Messages that may occur during Offline operations are
displayed on the library manager console and the remote library manager console if
the optional Remote Library Manager Console feature is installed.
Shutdown pending
The library manager closes and exits the library manager application.
Library Manager Switchover in Progress
When the high availability model is attached, this condition occurs when the active
and standby library managers switch roles. This can occur on a failure or request
by the operator. The library manager is in this state until the switchover completes.
Note: In case of a Library Manager failure, all attached hosts are notiļ¬ed and the
library is taken off line. There is a short delay while the switchover completes
and the operator must then vary the library on line. Any tape job that
abended (including those that use logical drives of a Virtual TapeServer)
must be resubmitted, and failed in-process tape operations must be
reissued. Library Manager console operations being performed by the
operator, including VTS-related operations, may require a restart.
Accessor Switchover in Progress
When the high availability model is attached, this condition occurs when the active
and standby accessors switch roles. This can occur on a failure or request by the
operator. The library is in this state until the switchover completes.
