Introduction

Purpose

Describing how to jumpstart a box so that it boot with RAID.

Scope

Foremost describe how to do this on Solaris 10 6/06.

This howto is for people that are familiar with jumpstart configuration, but new to getting RAID jumpstarted onto a box.

Acronyms

RAID: Redundant Array of Inexpensive Disks.
RAID-0: Striping, useing multiple disks as one volume.
RAID-1: Mirror, two or three disks looks exactly alike.
RIAD-Z: The true raid, with Suns new ZFS.
ZFS: Zetabyte File System.

References

Steps

You need to add instructions to three of the Jumpstart files: rules/rules.ok, begin.sh, finish.sh.
The profile is generated in the begin.sh, this is done to enable it to support both on and two disks.

Examples

begin.sh

sysidcfg

This is a minimal sysidcfg, just in case you don't have your own.

# Specify that no name service will be used. name_service=NONE # Do not specify the network interface. This will be set up by App Install. network_interface='NONE'{hostname=mirrorbox} # Do not use Kerberos security security_policy=NONE # Use the english language. system_locale=en_US # Set the terminal type terminal=vt100 # Specify that Universal Time Coordinates (also known as Greenwich Mean Time) # be used. timezone=UTC # Use the box being installed as the timekeeper. timeserver=localhost
