Library Manager Shutdown - IBM TotalStorage 3494 Tape Library Operator's Manual

Figure 51. 3953 Library Manager Shutdown
10. Set the power unit switch on the 3494 Lxx frame to the Off position.
Soft Shutdown of the Standby Library Manager
1. Select the Mode menu.
7. Select Shutdown computer for power-off... on the Shutdown window.
8. During this time, the Library Manager sends a command to each attached
subsystem to quiesce (that is, to perform a soft shutdown).
9. When the subsystem shutdown is complete, the subsystem displays either OK,
STBY, or 0507 on its display panel, and an information window on the Library
Manager opens with the following message:
Shutdown has completed.
It is now safe to turn off the Library Manager and all attached subsystems.
The subsystems and other components that can now be safely powered off
are:
v Library Manager A
v Library Manager B
v TSSC
v Library Manager display
v Tape controllers
Notes:
a. Library Manager A, Library Manager B, Library Manager display,
Tape controllers, and the Virtualization Engine TS7700 are power
sequenced off when you perform a soft shutdown.
b. The subsystems will remain in the 0507 state until either the
power button is pressed or power is physically removed.
If power is physically removed and restored, the subsystems will
power up fully and attempt to come online without pausing at the
OK or standby state.
If power is not physically removed, the subsystems remain in the
0507 state until the power button is pressed, which will shift the
subsystems to the OK or standby state. Pressing the power button
a second time will cause the subsystems to attempt to come online.
