B The Configuration File and Booting with OpenBoot PROM 2.0





In most standard configurations, when you install DSBE/S SBus cards on the system board, the devices are recognized automatically.

If you have a nonstandard configuration, you need to reconfigure the kernel. You also need to assign host information for the Ethernet port if it is being used. See the operating system documentation that was shipped with the software media for these procedures.

The OpenBoot PROM defines certain standard aliases: disk or disk 0 is the "first" disk, disk 1 is the "second" disk, disk 2 is the "third" disk, etc.

B.1 Booting from the CPU with OpenBoot PROM 2.0

The tables in this section identify boot paths. If your system is running Solaris 2.x, additional boot path information can be found in Appendix F.

Table B-1 shows a sample of the bootpaths that are available for booting a SPARCserver 600MP with OpenBoot PROM 2.0 and higher, under SunOS 4.x.

Table B-2 provides bootpath information for a SPARCcenter 2000 and a SPARCserver 1000.

Table B-3 provides bootpath information for a SPARCstation 10.

disk : same as disk 0
disk 1: the "second" disk
disk 2: the "third" disk, etc.

Certain standard disk*/scsi/net aliases for 2000 and 1000 systems are defined as follows:

The table and displays in this section identify boot paths. If your system is running Solaris 2.x, additional boot path information can be found in Appendix F.

Table B-5 shows the bootpaths that are required to boot from DSBE/S devices.

For a DSBE/S card in slot 1, the path changes to:

For a DSBE/S card in slot 2, the path changes to:

For a DSBE/S card in slot 3, the path changes to:

If you want information about the valid path names on your machine, type these commands:

The pathname for each device is displayed on the screen.

B.3 Running Extended Selftest

If you want to run extended selftest automatically after system reset, set the mode switch on the front panel of the CPU to the DIAG position.

Note - Selftest runs after system reset each time, automatically, if the mode switch is in the DIAG position. If you do not want selftest to run each time, set the mode switch on the front panel of the CPU to NORMAL.

To manually run FCode selftest, type these commands:

To test every SBus card on the system that has selftest built into its FCode PROM, at the ok prompt type:

To test the SCSI on a SPARCserver 600MP product, at the ok prompt type:

To test the Ethernet on a SPARCserver 600MP product, at the ok prompt type:
