System Configuration Card and OpenBoot Configuration Parameters

This appendix provides information on the system configuration card (SCC) and the OpenBoot PROM configuration parameters stored on it. For more on the SCC, see System Configuration Card.

The system configuration card is housed in a slot behind the front bezel, next to the On/Standby button (see FIGURE C-1). The card contains unique network identity information, including the MAC address and hostid (stored in the IDPROM), and the OpenBoot PROM configuration (also known as NVRAM).

FIGURE C-1 Location of the System Configuration Card

This figure shows the location of the system configuration card when it is inserted in its slot. The front bezel is open.

The server attempts to access the system configuration card while booting.

If a properly formatted card is not present in the reader, the system does not boot.

If the content of the NVRAM section is invalid, the system is initialized with its default NVRAM configuration. The default values can be seen using the printenv command.

If the content of the IDPROM section is invalid, OpenBoot PROM displays a warning message and the system does not auto-boot the Solaris platform. However, you can boot the system from the ok prompt using the boot command.

It is therefore essential that you store the system configuration card safely if you have to remove it from the server, and replace the card before restarting the system.

For more information, see System Configuration Card. passes

TABLE C-1 OpenBoot PROM Configuration Parameters Stored on the System Configuration Card
Parameter	Default	Description
`diag-passes`	`1`	Defines the number of times self-test method(s) are performed.
`asr-policy`	`normal`	Defines the policy to be implemented by the `asr-package`.
`local-mac-address?`	`true`	If `true`, network drivers use their own MAC address, not that of the server.
`fcode-debug?`	`false`	If `true`, includes name fields for plug-in device FCodes.
`ttyb-rts-dtr-off`	`false`	If `true`, operating system does not assert `ttyb`, RTS, and DTR.
`ttyb-ignore-cd`	`true`	If `true`, operating system ignores carrier-detect on `ttyb`.
`ttya-rts-dtr-off`	`false`	If `true`, operating system does not assert `ttya` and RTS and DTR.
`ttya-ignore-cd`	`true`	If `true`, operating system ignores carrier-detect on `ttya`.
`silent-mode?`	`false`	Suppresses all messages if `true` and if `diag-switch?` is `false`.
`scsi-initiator-id`	`7`	SCSI-ID of the SCSI controller.
`oem-logo`	`none`	Contains custom logo for banner, enabled by `oem-logo?`
`oem-logo?`	`false`	If `true`, uses custom OEM logo, otherwise, uses Sun logo.
`oem-banner`	NA	Contains custom banner text, enabled by `oem-banner?`
`oem-banner?`	`false`	If `true`, uses custom OEM banner.
`ansi-terminal?`	`true`	If `true`, uses ANSI terminal.
`screen-#columns`	`80`	Sets number of columns on screen.
`screen-#rows`	`34`	Sets number of rows on screen.
`ttya-mode`	`9600,8,n,1,-`	`ttya` (baud rate, #bits, parity, #stop, handshake).
`ttyb-mode`	`9600,8,n,1,-`	`ttyb` (baud rate, #bits, parity, #stop, handshake).
`output-device`	`ttya`	Console output device.
`input-device`	`ttya`	Console input device.
`auto-boot-on-error?`	`false`	If `true`, boots client program on firmware error/s. If `false`, does not boot on firmware error.
`load-base`	`16384`	Address.
`auto-boot?`	`true`	If `true`, boots automatically after power on or reset.
`boot-command`	`boot`	Action following a `boot` command.
`diag-file`	`none`	File from which to boot if `diag-switch?` is `true`.
`diag-device`	`net`	Device from which to boot if `diag-switch?` is `true`.
`boot-file`	`none`	File to boot if `diag-switch?` is `false`.
`boot-device`	`disk net`	Device(s) from which to boot if `diag-switch?` is `false`.
`use-nvramrc?`	`false`	If `true`, executes commands in NVRAMRC during server startup.
`nvramrc`	`none`	Command script to execute if `use-nvramrc?` is `true`.
`security-mode`	`none`	Firmware security level (options: `none`, `command`, or `full`).
`security-password`	`none`	Firmware security password if `security-mode` is not `none` (never displayed). Do not set this directly.
`security-#badlogins`	`none`	Number of incorrect security password attempts.
`post-trigger`	`power-on-reset`	Matches the class of reset.
`diag-script`	`none`	Determines which devices are tested by OpenBoot diagnostics.
`diag-level`	`max`	Defines how diagnostic tests are run (options are `off`, `min`, `med`, `max`).
`diag-switch?`	`false`	If `true`: Runs in diagnostic mode. After a `boot` request, boots `diag-file` from `diag-device`. If `false`: Runs in nondiagnostic mode. Following a `boot` request, boots `boot-file` from `boot-device`.
`obdiag-trigger`	`power-on-reset`	Class of reset events that causes OpenBoot diagnostics tests.
`error-reset-recovery`	`boot`	Command to execute following a system reset generated by an error.
