From the host console, dismount the logical units in the
subsystem. If you are using a Windows NT® platform, shut
down the server.

If the controller is operating, connect a PC or terminal to the
controller’s maintenance port.

If the controller is not operating, go to step 5.

Run FMU to obtain the last failure codes, if desired.
CAUTION: The cache module may contain data if the controller
crashed and you weren’t able to shut it down with the
SHUTDOWN controller command.

Shut down the controllers. In single controller
configurations, shut down “this controller.” In dualredundant controller configurations, shut down the “other
controller” first, then shut down “this controller” with the
following commands:
SHUTDOWN OTHER_CONTROLLER
SHUTDOWN THIS_CONTROLLER

When the controllers shuts down, their reset button and the
first three LEDs are lit continuously. This may take several
minutes, depending on the amount of data that needs to be
flushed from the cache modules.
CAUTION: Electrostatic discharge (ESD) can easily damage a
controller. Wear a snug-fitting, grounded ESD wrist strap.

Figure 3. HSZ80 Array Controller
NOTE: The maintenance port cable shipped with the HSG80 and
HSZ80 array controller has a 9-pin connector for a PC
connection only. If you are using a terminal instead of a PC, you
can order the optional maintenance port cable from the local
field service office.

Remove the program card’s ESD cover and program card.
Save them for the new controller.
NOTE: One or two host bus cables [HSG80] or one or two trilink
connectors with host bus cables (or terminators) [HSZ80] may
be attached, depending on the configuration.

Disconnect the host bus cables from the controller [HSG80]
using needle nose pliers (see Figure 4), or disconnect the
trilink connectors from the controller, but don’t disconnect
the host bus cables (or terminators) from the trilink
connectors [HSZ80].

Configure the controller as described in the appropriate
HSG80 Array Controller ACS Version 8.x User’s Guide or
the HSZ80 Array Controller ACS Version 8.x User’s Guide.
NOTE: If the controller you’re installing was previously used in
another subsystem, purge its old configuration. See
“CONFIGURATION RESET” in the appropriate HSG80 Array
Controller ACS Version 8.x User’s Guide or the HSZ80 Array
Controller ACS Version 8.x User’s Guide.

To restore a configuration saved with the
SAVE_CONFIGURATION switch, hold button 6 while
releasing the reset button.

Using CLCP, install any patches that you had installed on the
previous controller as described in the appropriate HSG80
Array Controller ACS Version 8.x User’s Guide or the
HSZ80 Array Controller ACS Version 8.x User’s Guide.

Mount the logical units on the host. If you are using a
Windows NT platform, restart the server.

If connected, disconnect the PC or terminal from the
controller’s maintenance port.

10. Set the subsystem date and time with the following
command:

Disengage both retaining levers and remove the controller,
then place the controller into an approved antistatic bag or
onto a grounded antistatic mat.

11. Disconnect the PC or terminal from the controller’s
maintenance port.

Installing a Controller
Use the following steps to install a new controller:

12. In a dual-redundant controller configuration, repeat the
procedure for the “other controller.”

CAUTION: ESD can easily damage a controller. Wear a snugfitting, grounded ESD wrist strap.
Make sure you align the controller in the appropriate guide rails.
If you do not align the controller correctly, damage to the
backplane can occur.
1.

Ensure that the program card is not in the new controller and
insert the new controller into its slot. Engage its retaining
levers.
NOTE: One or two host bus cables [HSG80] or one or two trilink
connectors with host bus cables (or terminators) [HSZ80] may
be attached, depending on the configuration.

Connect the host bus cables to the new controller [HSG80],
or connect the trilink connectors to the new controller
[HSZ80].

Connect a PC or terminal to the controller’s maintenance
port.

Hold the reset button while inserting the program card into
the new controller. Release and replace the ESD cover.

When the CLI prompt reappears, display details about the
controller you configured. Use the following command:
