Resetting the System

For NIO systems, refer to Appendix A for details about using the AP support interface for

functions other than resetting the system. For A and N class systems, refer to Appendix H

for details about using the GSP support interface for functions other that resetting the

system.

To reset the system using the access port (AP), or Guardian Service Processor (GSP),

follow the directions listed below:

1. Place the console in control mode by entering

CTRL B at the system prompt.

The console responds by displaying the control mode prompt (CM>) and activating the

system status line at the bottom of the screen:

CM>

Code: F1FF REMOTE: disabled inactive multiple ACCESS

FAULT:00

For A and N-class systems, the console responds by displaying the GSP mode prompt

(GSP>) along with a status message.

Leaving Console Mode - you may lose write access.

When Console Mode returns, type ^Ecf to get console write access.

GSP Host Name: <GSP host name>

GSP>

2. Issue the reset command. Enter: CM> SP

NOTE If you have a 99X system, you must transfer to the service processor before

you reset the system.

CM> RS ** Hard reset **

CM> TC ** Soft reset **

If you have a 9X8LX or 9X8RX system, a PDC menu is displayed when you issue

CTRL B.

From that menu, you can proceed to boot your system by typing BO. No speciﬁc reset is

required.

TC Transfer of control (soft reset). This command initiates a reset that preserves the

current processor state, terminates all I/O operations, and performs a

nondisruptive memory test.
