HP-UX Virtual Partitions Administrator's Guide (includes A.03.05 and A.04.05)

Using make_tape_recovery and Dual-media Boot
A dual-media boot allows you to boot the target partition using another disk and then recover
using the tape device. Currently with Ignite-UX, you cannot boot over the network and then
recover from tape; you must boot from a disk device.
Setting Up a Disk for Dual-Media Recovery
IMPORTANT: Dual-media recovery is only supported if you boot the install kernel from the
same version of Ignite-UX that was used to create the recovery tape. HP does not support using
mismatched versions of Ignite-UX.
Before attempting a dual-media recovery, you must set up a disk that contains the Ignite-UX
install kernels. You can do this in one of the following ways:
• If the virtual partition to be recovered is up, run bootsys from your Ignite-UX server. Do
not reboot the partition immediately. Confirm that the boot path and the kernel to be loaded
(/stand/WINSTALL for PA-RISC servers and /stand/IINSTALL for Integrity servers)
have been set correctly, as the bootsys command has limited support for vPars. If they are
not correct, use vparmodify to correct them. You can also shut the system down and boot
the vPar using the Ignite-UX install kernel explicitly, for example:
winona1# vparboot -p winona2 -B io_hw_path -b /stand/WINSTALL
• Alternatively you can manually place the install kernel and file system from Ignite-UX in
/stand (WINSTALL and WINSTALLFS for PA-RISC servers and IINSTALL and IINSTALLFS
for Integrity servers, then use vparboot to boot from the install kernel.
• If the system has a Fibre Channel interface that supports boot, and you have an unused
Fibre Channel LUN available, you can create a minimal CD/DVD boot image using the
procedure in the “How do I create the CD equivalent of a tape created by
make_boot_tape?” section of the Ignite-UX Custom Configuration Files manual available
at:
http://www.docs.hp.com/en/IUX/infolib.html
Once you have created the image you can dd it onto the Fibre Channel LUN and then boot
from the FC LUN using the following command from another vPar:
winona1# vparboot -p winona2 -B io_hw_path -b :WINSTALL
• If the virtual partition contains a DVD or CD drive, you can create a minimal CD/DVD boot
image as described in the Ignite-UX Custom Configuration Files, burn it to a CD or DVD, and
boot from that. Alternatively, you can boot the virtual partition from your OE media
(assuming it has the same version of Ignite-UX on it as the tape was created with).
Recovering the Virtual Partition
NOTE: The target virtual partition (the partition that is being recovered) must own a tape
device.
1. If needed, make sure the target virtual partition is in the down state. For example, if it is up,
shutdown the virtual partition:
winona2# shutdown -hy 0
2. Boot the virtual partition. The exact vparboot command line depends on how you set up
the install kernels. For example, if you used bootsys, use this command:
winona1# vparboot -p winona2 -B hardware_path -b /stand/WINSTALL
3. When the main Ignite-UX menu is displayed, select Install HP-UX.
