Dual Controller Configurations

Use this procedure for the following configurations:

HSG80 ACS Version 8.2 Dual-Redundant Controller 

HSG80 ACS Version 8.3 Dual-Redundant Controller 

HSG80 ACS Version 8.4 Dual-Redundant Controller 

HSG80 ACS Version 8.5 Dual-Redundant Controller 

HSZ80 ACS Version 8.3 Dual-Redundant Controller 

Use the steps in “Removing a Controller” and “Installing a 
Controller”
 to replace a controller. See the applicable array controller 
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. Connect a PC or terminal to the maintenance port of the 

operational controller.

The controller connected to becomes “this controller”; the 
controller being removed becomes the “other controller.”

2. Disable failover and take the controllers out of their 

dual-redundant configuration with the following command:

SET NOFAILOVER

3. Remove the program card ESD cover and program card from the 

“other controller.” Save them in a static-free place for the 
replacement controller.

4. Start FRUTIL with the following command:

RUN FRUTIL

5. If a replace the cache battery question appears, enter N(o).

6. Enter option 1Replace or remove a controller or cache module

from the FRUTIL Main menu.

7. Enter option 2Other controller module, from the Replace or 

Remove Options menu to remove the “other controller.”

8. Enter Y(es) to confirm the intent to remove the “other controller.”

CAUTION:  

Wait for FRUTIL to quiesce the device ports—indicated by an “All 

device ports quiesced” message. Failure to allow the ports to quiesce might 
result in data loss. This might take several minutes.

NOTE:  

A countdown timer allows a total of two minutes to remove the controller. 

After two minutes, “this controller” will exit FRUTIL and resume operations. If 
this happens, return to step 4 and proceed.

9. Follow on-screen instructions to remove the controller.

10. Disconnect all host bus cables from the “other controller:”

[HSG80] If extender clips are not installed on the cables, use 
thin needle nose pliers to disconnect the cables (see Figure 5).

[HSZ80] Disconnect the trilink connector from the controller 
(the trilink connectors are reused, see Figure 3).

11. Place the controller in an antistatic bag or on a grounded antistatic 

mat.

12. Enter N(o) if a replacement controller is not available.

FRUTIL will exit.

Disconnect the PC or terminal from the controller 
maintenance port.

Enter Y(es) if a replacement controller is available and it will be 
installed now.

NOTE:  

If 

Y

(es) was entered, go to step 6 in the next section and proceed.

Installing a Controller

Use the following steps to install a controller.

1. Connect a PC or terminal to the operational controller.

The controller connected to becomes “this controller”; the 
controller being installed becomes the “other controller.”

2. Start FRUTIL with the following command:

RUN FRUTIL

3. If a replace the cache battery question appears, enter N(o).

4. Enter option 2Install a controller or cache module, from the 

FRUTIL Main menu.

5. Enter option 2Other controller module, from the Replace or 

Remove Options menu.

6. Enter Y(es) to confirm the intent to install the “other controller.”

CAUTION:  

Wait for FRUTIL to quiesce the device ports—indicated by an “All 

device ports quiesced” message. Failure to allow the ports to quiesce might 
result in data loss. This might take several minutes.

Carefully align the controller in the appropriate guide rails. Misalignment 
might damage the backplane.

NOTE:  

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. Follow on-screen instructions to install and start the controller.

8. Make sure that the program card is seated in the replacement 

controller, insert the controller into its bay, and engage its 
retaining levers.

NOTE:  

When fully seated, the newly installed controller restarts automatically.

9. Install the program card ESD cover on the “other controller.”

10. Wait for FRUTIL to terminate and then reconnect the host bus 

cables:

[HSG80] cables only

[HSZ80] host bus cables with trilink connectors

11. 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, it will need to be purged of the old configuration (see CONFIG RESET 
in the appropriate array controller User Guide or CLI Reference Guide.).

12. Enable failover, and re-establish the dual-redundant configuration 

with the following command:

SET FAILOVER COPY=THIS_CONTROLLER

This command copies the subsystem configuration from “this 
controller” to the “other controller.”

13. If desired, verify the failover configuration with the following 

command:

SHOW THIS_CONTROLLER FULL

14. Disconnect the PC or terminal from the controller maintenance 

port.

This completes the hardware installation.
