Follow these steps to remove a controller.
1.

Connect a terminal to the operational controller’s
maintenance port. The controller to which you’re connected
is “this controller;” the controller that you’re removing is the
“other controller.”

All device ports quiesced.
Remove the slot B controller (the one without a

NOTE: A countdown timer allows a total of two minutes to
remove the controller. If you exceed the two minutes, “this controller” will exit FRUTIL and resume operations.

Install Options:
1. Other controller and cache module
2. Other controller module
3. Other cache module

CAUTION: An electrostatic discharge (ESD) can easily damage
a controller or cache module. Wear an ESD wrist strap on your
wrist, make sure the strap fits snugly, and attach the ESD strap's
grounding lead to a verified earth ground.

Choose option 2, Other controller module, from the Install
Options menu to install the “other controller:”

4. Exit
Enter choice: 1, 2, 3, or 4 -> 2

Remove the ESD cover and program card. Save them for the
new controller.

Confirm that you want to install the “other controller.”
FRUTIL displays the following:
Insert the slot B controller? Y/N

10. Remove the trilink connectors from the “other controller”
but don’t disconnect the bus cables (or terminators) from the
trilink connectors.

Type Y(es) and press return.

Wait for FRUTIL to quiesce the device ports. After the ports
have been quiesced (this may take several minutes), FRUTIL
displays the following:

NOTE: One or two trilink connectors may be attached, depending on the configuration.

All device ports quiesced.
Insert the controller module, without its program
card, in slot B within x minutes, xx seconds.

11. Disengage the two retaining levers, and remove the “other
controller,” and place the controller into an approved
antistatic bag or onto a grounded antistatic mat.

NOTE: A countdown timer allows a total of two minutes to
install the controller. If you exceed the two minutes, “this controller” will exit FRUTIL and resume operations.

12. Once the controller is removed, FRUTIL displays the
following:
Restarting all device ports. Please wait...

Do you have a replacement controller? Y/N

Installing a Controller in a Dual-Redundant
Controller Configuration
Follow these steps to install a controller.

Wait for FRUTIL to terminate.

NOTE: One or two trilink connectors may be attached, depending on the configuration.

Connect a terminal to the operational controller’s
maintenance port. The controller to which you’re connected
is “this controller;” the controller that you’re installing is the
“other controller.”

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

Start FRUTIL with the following command:
NOTE: This procedure assumes that a new controller is being
installed. If the controller you’re installing was previously used
in another subsystem, it will need to be purged of the controller’s
old configuration.

RUN FRUTIL

Ensure that the program card is NOT in the new controller
and insert the new controller into its slot. Engage its
retaining levers.

10. Connect the trilink connectors to the new controller.

NOTE: If you selected Y(es) in step 12 in the removal procedure—for a continuous removal and installation—go to step 5.
1.

Choose option 2, Install a controller or cache module, from
the FRUTIL Main Menu:

12. Enable failover, and re-establish the dual-redundant
controller configuration with the following command:

SET FAILOVER COPY=THIS_CONTROLLER

This command copies the subsystem’s configuration from
“this controller” to the new controller.

Installing the Controller in a Single Controller
Configuration
Follow these steps to install the controller.

Replacing the Controller in a Single
Controller Configuration

CAUTION: An electrostatic discharge (ESD) can easily damage
a controller. Wear an ESD wrist strap on your wrist, make sure
the strap fits snugly, and attach the ESD strap’s grounding lead to
a verified earth ground.

Follow these steps to replace the controller.
Removing the Controller in a Single Controller
Configuration
Follow these steps to remove the controller.

3.

Make sure you align the controller and cache module in the
appropriate card cage guide rails. If you do not align the modules
appropriately, damage to the backplane can occur.

From the host console, dismount the logical units in the
subsystem. If you are using a Windows NT platform, shut
down the PC.
If the controller is operating, connect a terminal to the
controller’s maintenance port.
Run FMU to obtain the last failure codes, if desired.

Insert the new controller into its slot, and engage its retaining
levers.

Connect the trilink connectors to the new controller.

NOTE: One or two trilink connectors may be attached, depending on the configuration.

If the controller is not operating, go to step 5.
CAUTION: The cache module may contain data if the controller
crashed and you weren’t able to shut it down with the SHUTDOWN THIS_CONTROLLER command.

Connect a terminal to the controller’s maintenance port.

Restore power to the subsystem.

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

If you won’t be installing a new controller within 24 hours, and if
the cache module is still holding data, then restore the power to
the subsystem after you’ve removed the failed controller. The
cache module will hold its data as long as it receives power from
the ECB. An ECB provides power for 24 hours or more depending on the amount of memory in the cache module.
4.

If the controller you’re installing was previously used in
another subsystem, it will restart with the configuration that
resides in its nonvolatile memory. If this differs from the
subsystem’s current configuration, you can purge the
controller’s old configuration with the following command:
SET THIS_CONTROLLER INITIAL_CONFIGURATION

Shut down the controller with the following command:

The controller shuts down after returning to its initial
configuration. Press its reset button to restart the controller
after the controller has been configured.

SHUTDOWN THIS_CONTROLLER

When the controller shuts down, its reset button and the first
three LEDs are lit continuously.
5.

If INITIALIZE container-name SAVE_CONFIGURATION
was used to save the controller’s configuration, you can
restore the configuration by using the CONFIGURATION
RESTORE command.

Turn off the power to the subsystem.

CAUTION: An electrostatic discharge (ESD) can easily damage
a controller. Wear an ESD wrist strap on your wrist, make sure
the strap fits snugly, and attach the ESD strap's grounding lead to
a verified earth ground.
6.
7.

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

Remove the ESD cover and program card. Save them for the
new controller.

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

Remove the trilink connectors, but don’t disconnect the bus
cables (or terminators) from the trilink connectors.

Set the subsystem date and time.

NOTE: One or two trilink connectors may be attached, depending on the configuration.
8.

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

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