HP-UX Virtual Partitions Administrator Guide (includes A.05.08) (5900-1312, March 2011)

8. Use vparboot -I to recover the other virtual partitions using the make_net_recovery
files created in step (2).
9. There may be normal filesystem recoveries that need to be done to fully recover the virtual
partitions after they are booted in step (8).
10. Modify the autoboot string (using mkboot -a ...) so that the virtual partitions will autoboot
at the next system boot.
11. Reboot the nPartition to test if all the virtual partitions come up as expected.
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 on the BSC website at:
www.hp.com/go/ignite-ux-docs
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).
