Installing an HSG80 Fibre Channel Controller GLM

This document contains instructions to install a gigabit link module (GLM) in an HSG80 ACS Version 8.x

Array Controller. See the appropriate

HSG80 Array Controller ACS Version 8.x User’s Guide

or

HSG80 Array

Controller ACS Version 8.x Maintenance and Service Guide

for instructions on upgrading a single controller

configuration to a dual-redundant controller configuration.

Figure 1. Location of GLMs in an HSG80 Controller

Replacing a GLM

Use this procedure for the following configurations :

HSG80 ACS Version 8.x Single Controller
HSG80 ACS Version 8.0 Dual-Redundant Controller

Use the following steps in “Removing a GLM” and “Installing a
GLM” to replace the GLM.

Removing a GLM

Use the following steps to remove a GLM:

1. From the host console, dismount the logical units in the
subsystem.

2. Connect a PC or terminal to the controller’s maintenance
port. Obtain the last failure codes, if desired.

3. Shut down the controllers. In single-cont roller
configurations, shut down “this controller.” In dual­redundant controller configurations, shut down the “other
controller” f i rst, the n shut down “this co n t r o ller” with the
following commands:

SHUTDOWN OTHER_CONTROLLER
SHUTDOWN THIS_CONTROLLER

When the controllers shut down, their reset buttons and their
first th r ee LEDs are lit continuously. this may take sever al
minutes, depend ing on the amount of data that nee ds to be
flushed from the cache module s.

CAUTION: Electrostatic discharge (ESD) can easily damage a
controller or GLM. Wear a snug-fitting, grounded ESD wrist
strap.

4. Remove the program card’s ESD cover and program card.
Save the m for installation later.

5. Disconnect the host b us cables from the controller using
needle nose plier s (see Fi gure 2).

NOTE: One or two host bus cables may be attached, depending
on the configuration.

6. Disconnect the PC or terminal from the controller’s

maintenance port.

7. Disengage both retaining levers and remove the controller.
Place the controller onto a grounded antis tatic mat.

8. Remove the screw that secures the acces s door on the top of
the cont r oller.

9. Remove the access door, and set it aside.

10. Disengage the GLM’s locking tabs that protrude through the
guide holes on th e bottom of the controller.

11. Use your inde x finger and thu mb t o operate the release lever
on the exposed end of the GLM. Press the lower end of the
release le ver with your index finger while pulling the raised
end of the release lever up with your thumb.

12. Remove the GLM.

Installing a GLM

Use the following st eps to install a GLM:

NOTE: Before inserting the new GLM, notice the holes in the
board where the GLM will reside.

1. Insert the new GLM by f irst placing the cable connecti on end
of the GLM through the open ing on the front of the
controller.

2. Line up the guide pins on the bottom of the replacement
GLM with the holes in th e board. Press fir mly to seat the
GLM.

3. Press the r elease le ver firmly into place to secure the GLM.

CAUTION: ESD can easily damage a controller or GLM. Wear a
snug-fitting, 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.

4. Insert the ne w control le r i nto its sl ot, a nd enga ge its retai ning
levers.

5. Connect the host bus cables to the new controller.

NOTE: One or two host bus cables may be attached, depending
on the configuration.

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

7. Hold the reset button while inserting the program card into
the new controller. Release and replace the ESD cover.
Repeat for the other con trolle r in a dual-redunda nt controll er
config uratio n.

8. When the CLI prompt reappears, display details about the
controller you installed. In single-c ontroller conf igurations,
show “this controller.” In dual-redundant controller
conf ig u rations, show “this controller” and the “other
cont r o ll er ” with th e f o ll ow in g comma nds:

SHOW THIS_CONTROLLER FULL
SHOW OTHER_CONTROLLER FULL

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

10. Set the subsystem date and time. In single controller
configurations, set “this controller.” In dual-redundant
controller con figurations, set “this controller” and the “other
cont r o ll er ” with th e f o ll ow in g comma nds:

SET THIS_CONTROLLER TIME=

dd-mmm-yyyy:hh:mm:ss

SET OTHER_CONTROLLER TIME=

dd-mmm-yyyy:hh:mm:ss

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

Replacing a GLM

Use this procedure for the following configurations :

HSG80 ACS Version 8.2 Dual-Redundant Controller

Use the following steps in “Removing a GLM” and “Installing a
GLM” to replace a GLM.

Removing a GLM

Use the following steps to remove a GLM:

1. Connect a PC or terminal to the operational controller. The
controller to which you’re connected is “this controller”; the
controller whose GLM you are replacing is the “other
controller.”

2. Disable failover with the following command:

SET NOFAILOVER

3. Start FR UTIL with the following command:

RUN FRUTIL

FRUTI L displays the following:

Do you intend to replace this controller’s cache
battery? Y/N

4. Enter N(o). FR UTIL displays the FRUTIL Main menu:

FRUTIL Main Menu:

1. Replace or remove a controller or cache module

2. Install a controller or cache module

3. Replace a PVA module

4. Replace an I/O module

5. Exit

Replace or remove Options:

1. Other controller and cache module

2. Other controller module

3. Other cache module

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

6. Enter optio n 2, Other contr oll er module, fr om t h e R epl ace o r

or B

] controller? Y/N

7. Enter Y(es) and press return. FRUTIL displays the
following:

Quiescing all device ports. Please wait...
Device Port 1 quiesced.
Device Port 2 quiesced.
Device Port 3 quiesced.
Device Port 4 quiesced.
Device Port 5 quiesced.
Device Port 6 quiesced.
All device ports quiesced.
Remove the slot A [

or B

] controller (the one without

a blinking green LED)

See Figure 3 for location of the controller.

Figure 3. Location of Controllers and Cache Module

CAUTION: The device ports must quiesce before removing the

cache module. Failure to allow the ports to quiesce may result
in data loss. Quiescing may take several minutes.

ESD can easily damage a controller or GLM. Wear a snug-fitting,
grounded ESD wrist strap.

NOTE: A countdown timer allows a total of two minutes to

remove the cache module. If you exceed two minutes, “this
controller” will exit FRUTIL and resume operations. If this
happens, go back to step 3.

8. Remove the program card’s ESD cove r and program card.
Save them for reinstallation later.

9. Disconnect the host bus cables from the “other controller”
using needle nose plie rs (see Figure 2).

NOTE: One or two host bus cables may be attached, depending
on the configuration.

10. Disengage both retaini ng levers, and remove the “other
controller.” Place the co ntroller onto a grounded ant is tatic
mat.

11. Once the controller is removed, FRUT IL displays the
following:

Restarting all device ports. Please wait...
Device Port 1 restarted.
Device Port 2 restarted.
Device Port 3 restarted.
