Single Controller Configurations
Use this procedure for the following configurations:
■
HSG80 ACS Version 8.2 Single Controller
■
HSG80 ACS Version 8.3 Single Controller
■
HSG80 ACS Version 8.4 Single Controller
■
HSG80 ACS Version 8.5 Single Controller
■
HSZ80 ACS Version 8.3 Single Controller
Use the steps in “Removing a Controller” and “Installing a
Controller” to replace a controller. See the applicable array controller
figure (Figure 1, 2, or 3) for clarification during the procedure.
CAUTION:
ESD can easily damage an array controller. Wear a snug-fitting,
grounded ESD wrist strap.
Removing a Controller
Use the following steps to remove a controller:
1. From the host console, dismount the logical units in the
subsystem. If using a Microsoft Windows NT platform, shut down
the server.
2. If the controller is operating, connect a PC or terminal to the
controller maintenance port.
If the controller is not operating, go to step 6.
3. Run the fault management utility (FMU) to obtain the last failure
codes, if desired.
4. Is a disk initialized with the SAVE_CONFIGURATION switch?
■
Yes. Use the following command to save the current device
configuration for “this controller:”
CONFIGURATION SAVE
■
No. Locate existing information that will support the manual
configuration of the subsystem. The new controller must be
manually configured as described using the appropriate array
controller User Guide or CLI Reference Guide.
5. Shut down “this controller” with the following command:
SHUTDOWN THIS_CONTROLLER
When the controller shuts down, the reset button
1 and the first
three light emitting diodes (LEDs)
2 turn O
N
(see Figure 4). It
might take several minutes for this indication to appear, depending
on the amount of data that needs to be flushed from the cache
module.

CAUTION:
The cache module might contain unwritten data if the controller
crashes and the controller cannot be shut down with the SHUTDOWN
THIS_CONTROLLER command.
6. Remove the program card ESD cover and the program card and
save them in a static-free place for the replacement controller.
