IBM TotalStorage 3494 Tape Library, Operator'S Manual

Page: 128 / 605

Initialization Complete
The 3494 Tape Library starts the Library Manager application and determines the
operational mode and state. The availability conditions of the components and
whether the 3494 Tape Library is taught and inventoried determine the mode and
state. If the 3494 Tape Library is taught and inventoried, the Library Manager
waits for one of the following conditions:
v
An operator instruction to proceed to an operational mode and operational state.
v A time-out interval expires. This causes the 3494 Tape Library to go to the
default operational mode and operational state that the availability conditions of
the 3494 Tape Library components set.
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. The
Library Manager processes commands that it received before entering the Offline
state.
Operations performed while the 3494 Tape Library is in the Offline state, such as
inventory, do not report errors to the host. The Library Manager console displays
messages that may occur during offline operations. If the Remote Library Manager
Console feature is installed, the Remote Library Manager Console also displays
such messages.
Shutdown Pending
The Library Manager closes and exits the Library Manager application.
Library Manager Switchover in Progress
When the 3494 HA1 Option is installed, this condition occurs when the active and
standby Library Managers switch roles. This can occur on a failure or by your
request. The Library Manager is in this state until the switchover completes.
Note:
You must resubmit any tape job that aborted (including those that use the
virtual tape drives of a VTS) and reissue failed in-process tape operations.
You may have to restart any Library Manager console operations that you
were performing, including VTS-related operations.
Accessor Switchover in Progress
When the 3494 HA1 Option is installed, this condition occurs when the active and
standby accessors switch roles. This can occur on a failure or by your request. The
3494 Tape Library is in this state until the switchover completes.
Dual Active Accessor Status
When the Dual Active Accessors feature is installed, it may be enabled or disabled.
Figure 48 on page 103 shows the window for the transition into Dual Active
Accessor mode. Figure 49 on page 103 shows the window for the transition out of
Dual Active Accessor mode. Each of these windows is shown until the transition is
complete.
