This document contains instructions for replacing an HSG60, HSG80,
HSJ80, or HSZ80 array controller.
NOTE: For instructions on upgrading a single-controller configuration to a
REPLACING AN dual-redundant controller configuration, see the appropriate array controller user
guide or maintenance and service guide.
HSG60 OR General Information
Figure 1, Figure 2, Figure 3, and Figure 4 provide general information
HSX80 ARRAY about the specific host cable connection for each array controller.
NOTE: The maintenance port cable shipped with the array controller has a 9-pin
CONTROLLER connector for a PC connection only. If using a terminal instead of a PC, order the
optional maintenance port cable from the local field service office.

This completes the hardware installation.
IMPORTAN T: A countdown timer allows a total of two minutes to install the
controller. After two minutes, "this controller" will exit FRUTIL and resume
operations. If this happens, return to step 2 and proceed.
7. Install the replacement controller:
a. Make sure that the program card is seated in the controller.
b. Insert the controller into the appropriate bay, and engage the
retaining levers.
NOTE: When fully seated, the controller starts automatically--the reset LED
turns ON.
A controller restart can take as long as 60 sec, indicated by the temporary
cycling of the port LEDs and a FLASHING reset button.
IMPORTAN T: If the "other controller" did not restart, use the following steps:
1. Press and hold the "other controller" reset button.
2. Reseat the "other controller" program card.
3. Release the reset button.
8. Press Enter/Return to continue.
FRUTIL exits.
9. Install the program card ESD cover on the "other controller."
10. Configure the controller as described in the appropriate array
controller user guide or CLI reference guide.
NOTE: If the controller being installed was previously used in another
subsystem, purge the controller of the old configuration (refer to the
CONFIGURATION RESET command description in the appropriate array controller
user guide or CLI reference guide).
11. Enable failover and reestablish the dual-redundant configuration
with one of the following commands:
SET FAILOVER COPY=THIS_CONTROLLER
or
SET MULTIBUS_FAILOVER COPY=THIS_CONTROLLER
This command copies the subsystem configuration from "this
controller" to the "other controller."
12. If desired, verify the failover configuration with the following
command:
SH OW THIS_CONTROLLER FULL
13. Wait for FRUTIL to terminate and then reconnect the host bus
cables or terminators:
s [HSG60 or HSG80] Reconnect the optical or copper cables
(see Figure 1 or Figure 2, respectively).
s [HSJ80] Reconnect the internal CI cables (see Figure 3).
s [HSZ80] Reconnect the trilink connectors (see Figure 4).
14. For HSJ80 controllers:
a. Enable CI bus paths with the following commands:
SET THIS_CONTROLLER PORT_1_PATH_A
SET THIS_CONTROLLER PORT_1_PATH_B
SET THIS_CONTROLLER PORT_2_PATH_A
SET THIS_CONTROLLER PORT_2_PATH_B
