SPARC and IA Information

This book provides system administration information for both SPARC and IA systems. Unless otherwise noted, information throughout this book applies to both types of systems. Table A summarizes the differences between the SPARC and IA system administration tasks.

SPARC Platform

IA Platform

System operation before kernel is loaded

A programmable read-only memory (OpenBoot PROM) chip with a monitor program runs diagnostics and displays device information.

The OpenBoot PROM is also used to program default boot parameters and to test the devices connected to the system.

The basic input/output system (BIOS) runs diagnostics and displays device information.

A Solaris Device Configuration Assistant boot diskette with the Multiple Device Boot (MDB) program is used to boot from nondefault boot partitions, the network, or the CD-ROM.

Booting the system

Commands and options at the OpenBoot PROM level are used to boot the system.

Commands and options at the MBD, primary, and secondary boot subsystems level are used to boot the system.

Boot programs

bootblk, the primary boot program, loads ufsboot. ufsboot, the secondary boot program, loads the kernel.

mboot, the master boot record, loads pboot. pboot, the Solaris partition boot program, loads bootblk. bootblk, the primary boot program, loads ufsboot.

ufsboot, the secondary boot program, loads the kernel.

System shutdown

The shutdown and init commands can be used without additional operator intervention.

The shutdown and init commands are used but require operator intervention to type any key to continue the prompt.

Disk controllers

SCSI, IDE.

SCSI and IDE.

Disk slices and partitions

A disk may have a maximum of eight slices, numbered 07.

A disk may have a maximum of four fdisk partitions.

The Solaris fdisk partition may contain up to 10 slices, numbered 09, but only 07 can store user data.

Diskette drives

Desktop systems usually contain one 3.5-inch diskette drive.

Systems may contain two diskette drives: a 3.5-inch and a 5.25-inch drive.
