HP-UX Virtual Partitions Administrator Guide (includes A.05.07) (5900-1229, September 2010)

Example:
— If you have a backup copy of the partition database in the file /stand/vpdb.backup,
you can read the database configuration information using:
MON> readdb /stand/vpdb.backup
Notes:
— This command can only be used when the vPars Monitor /stand/vpmon is booted
and the default partition database (/stand/vpdb) does not exist, the alternate partition
database as specified in the -D option of /stand/vpmon does not exist, or the database
file read is corrupt. For more information on the -p option, see “vPars Monitor: Booting
the vPars Monitor” (page 134).
Integrity only: If you issue readdb /stand/vpdb.backup, the file that is actually
read is at /stand/boot.sys/stand/vpdb.backup. The vparcreate command
transparently creates the soft link from /stand/boot.sys/stand/file to
/stand/file. Therefore, if you backup the database file using the Unix cp command,
the ln -s command also should be executed to create the soft link. Otherwise, it will
not be possible to boot from the backup database file.
• vparload -all
vparload -auto
vparload -p partition_name -b kernelpath -o boot_options -B
hardware_path [-D disk_index] [-E disk_index]
boots the virtual partition partition_name; this command is similar to the vPars Unix
shell command vparboot.
Boots all virtual partitions, regardless of the autoboot or autosearch attributes.
For more information on the autoboot or autosearch attributes, see the
vparcreate(1M) or vparmodify(1M) manpages.
-all
Boots all virtual partitions that have their autoboot attribute flag set to AUTO.-auto
Boots the virtual partition using the kernel kernelpath instead of the default kernel-b kernelpath
Boots the virtual partition using the options boot_options, such as -is for
single-user mode or -lm for LVM maintenance mode.
-o boot_options
Boots the virtual partition using the disk device at the hardware_path-B hardware_path
(Integrity only) Supported by vPars A.05.02 and later. Launches the install kernel
from the CD or DVD media specified by disk_index. If the disk_index specified
is “X” the install kernel is launched from the disk “fsX:”. If installable media is not
present at the index specified, the virtual partition will be shut down and the user
must select a different disk_index.
-D disk_index
(Integrity only) Launches the vPars boot helper EFI application from the disk specified
by the disk_index. The EFI boot helper prints the EFI paths of all the bootable disks
belonging to the target virtual partition and prompts the user to select a disk to boot
from.
Under vPars A.05.02 and later, if the disk selected is a CD or DVD device, then the
install kernel from the media is launched instead of the regular kernel and any boot
options specified on the command line are ignored.
-E disk_index
Examples:
— To boot the partition winona2 into single-user mode:
MON> vparload -p winona2 -o "-is"
— To boot the partition winona2 using the kernel /stand/vmunix.prev:
MON> vparload -p winona2 -b /stand/vmunix.prev
— To boot the partition winona2 using the disk device at 0/8/0/0.2.0:
