13. Determine whether the configuration restore
process completed successfully, and then perform
one of the following options:
■ Perform the following substeps if the
configuration restore process did not complete
successfully.
a. Reset the PC or terminal baud rate to
match the original configuration of the
controller.
b. Repeat step 10 and step 11 (on page 4).
c. Proceed to the next step after a successful
configuration.
■ Proceed to the next step if the configuration
restore process completed successfully.
14. Connect all host bus cables or terminators to the
controller.
15. Mount the logical units on the host.
16. Restart the server if you are using Windows NT or
Windows 2000.
17. Disconnect the PC or terminal from the controller
maintenance port.
18. Install the program card ESD cover (see Figure 6 on
page 3).
Replacing HSG60 and HSG80 controllers
in dual-redundant controller
configurations
Perform the steps in the following subsections to replace an
HSG60 or HSG80 array controller in a dual-redundant
configuration.
To differentiate on which component activity is being
completed, symbols are displayed in the margin of text for
your convenience. Table 2 describes the symbols.
Removing a controller
Perform the following steps to remove a controller in a
dual-redundant controller configuration:
 1. If the controller to be replaced () is functional,
complete the following substeps. Otherwise, go to
step 2.
 a. Connect a PC or terminal to the maintenance
port of the controller.
 b. Press Enter or Return 2 or 3 times to display
the controller prompt.
c. Start the Virtual Terminal Display (VTDPY)
Utility by entering the following command:
RUN VTDPY
 d. Record which units have I/O activity.
 e. Exit VTDPY by pressing Ctrl+Y.
 f. Restart the controller by entering the following
command:
RESTART THIS_CONTROLLER
Note: Restarting the controller ensures that the unit persistent
reservation flags transfer to the operational controller.
 g. Disconnect the PC or terminal from the
maintenance port.
 2. For the operational controller (), complete the
following substeps:
 a. Connect a PC or terminal to the maintenance
port of the operational controller (see Figure 4
on page 3).
Note: The controller connected to the PC or terminal becomes “this
controller.” The controller being removed becomes the “other
controller.”
 b. Set the terminal baud rate to match the controller
baud rate, and then press Enter or Return 2 to 3
times to display the controller prompt.
 c. Display and note configuration information (for
example, the Failover mode, Cache mode, serial
numbers, SCSI mode, and so forth) for the
operational controller by entering the following
command:
SHOW THIS_CONTROLLER
 d. Verify that the I/O for the controller that is being
replaced fails over to the operational controller
(see substep 1d) by entering the following
command:
RUN VTDPY

which is
not being replaced.
 Indicates that the procedural step must be
completed for the
controller that has failed
or is to be replaced
.
H
Indicates that the procedural step must be
completed for the
field replaceable unit
(FRU) or new or replacement controller
being installed
.
