HP-UX 11i v3 Installation and Update Guide, February 2007 (Initial Release)

Preparing to Cold-Install or Update to HP-UX 11i v3
Backing Up Your System
Chapter 474
If you intend to use a tape drive other than the default (/dev/rmt/0m),
modify the command to point to the device you want to use, for example,
a tape drive at /dev/rmt/3mn:
/opt/ignite/bin/make_tape_recovery -Av -a /dev/rmt/3mn
To recover a failed system disk or volume group after an operating
system recovery tape has been made, simply load the recovery tape, boot
the system and interrupt the boot sequence to redirect to the tape drive.
Allow the install process to complete. Do not intervene. The system will
reboot and, because map files for all associated volume groups have been
saved on the tape, any other existing volume groups are imported and
mounted automatically. Data that is not in the root volume group must
be backed up and recovered using normal backup utilities.
For more information on using make_tape_recovery, refer to the
make_tape_recovery (1M) manpage on an Ignite-UX server or the
Ignite-UX Administration Guide. The guide is available on the HP
Technical Documentation Web site:
