IBM Tape Library Magstar 3494 - Manual (Page 299)

Operator Note: The primary aids for problem determination should be the
messages posted on the host console. Use the information at the
library manager console only as additional information to aid in
finding the fault.
Using the System Summary Window
The System Summary window (see Figure 43 on page 98) provides an overall view
of the status of the library. If the System Summary window is not displayed on the
console, use the Status pull-down and choose System summary. Table 13
summarizes the key fields and what action to take.

Cannot Display System Summary
If the System Summary window cannot be displayed, a
failure has occurred in the library manager.
Contact your service representative.
Operational Mode
Auto should be indicated showing normal operation.
Pause shows that the library has stopped performing
automated operations.
1. Determine why the mode is not Auto.
2. Check the Enclosure doors, Overall system, and
Intervention fields.
3. Ensure that the front doors are closed.
4. Place the library in Auto mode.
Library Manager
Online should be indicated showing normal operation.
Offline shows that the library manager is not
communicating with any of the associated 3490E/3590
subsystems in the library.
1. Determine why the library manager is Offline.
2. Place the library manager in the Online state.
Enclosure doors
Closed should be indicated showing normal operation.
Open indicates that one or more doors are open and that
automated operations are paused.
1. Ensure that the front doors are closed.
2. Return the library to Auto mode.
3. If the library cannot be set to Auto mode, contact your
service representative.
Direct attached ports
A hexadecimal number, 0–3 and 8–B, should be
displayed for each installed and initialized port. If a dash
is displayed, that port is not initialized.
1. Ensure that the host is powered on and operating.
2. Ensure that the any device driver program on the host
is initialized.
3. Contact your service representative.
CU ports
A hexadecimal number, 0–F (depending on the port
configuration), should be displayed for each 3490E/3590
control unit port. If a dash is displayed, that port is not
initialized. No communication between the library
manager and the 3490E/3590 control unit occurs. If the
port to a 3490E/3590 subsystem is not initialized,
automated operations for the drives in that subsystem
cannot be performed.
1. Ensure that all 3490E/3590 subsystems in the library
are powered on. Perform the power-on procedure for
the 3490E/3590 subsystems.
2. Check the Error indicator on the 3490E/3590 control
unit setup panel. If illuminated, that control unit has a
serious fault; contact your service representative to
repair the control unit.
3. Contact your service representative.
