Abstract
The bane of all system administrators is the crashing of a mission
critical system. Further depression sets in when the crash has caused
the boot disk to become corrupted and no longer possess the ability to
boot the system. A crashed mission critical system requires immediate
attention. Literally, every moment of downtime equates to lost
revenue. The desire is to get the mission critical system back to its
normal functioning state in the quickest amount of time. The
rebuilding of a computer system that has lost its capability to boot
is known as a bare-metal recovery. The system will need to be built
starting from a bare disk drive up to a bootable and functioning
operating system.
Not until the release of Solaris 8 did the Solaris operating
system contain a utility for providing bare-metal recovery
functionality. Such functionality can be found in the operating system
of other UNIX variants, such as IBM AIX, HP HP-UX, and Linux. However,
by making use of the following Solaris utilities:
ufsdump, ufsrestore, dd,
cpio, tar, format,
prtvtoc, fmthard,
installboot, and JumpStart, bare-metal
recovery can be achieved. Furthermore, it can be achieved by using a
custom-built bootable CD-ROM (or DVD-ROM) and your environment's
networked enterprise backup solution, such as Legato NetWorker and
Veritas NetBackup.
