You can use the following vPars Monitor commands
at the vPars Monitor prompt for booting and basic troubleshooting.
However, most vPars operations should be performed using the vPars
shell commands. Note the following for the vPars Monitor commands: Unless specifically stated,
all operations occur only on the boot disk from which the vPars Monitor
was booted. Usually, this is the boot disk of the primary path entry
in system-wide stable storage. Further,
the vPars Monitor can traverse only HFS file systems. Usually, the
only HFS file system is /stand. Except for the vparload command, an alternate disk device cannot be specified
using the vPars Monitor commands. The following vPars Monitor
commands are disabled when one or more virtual partitions are up: getauto, lifls, and readdb.
The following vPars Monitor
commands are disabled when the virtual partition that owns the disk
from which the vPars Monitor was booted, usually the primary path,
is up:

readdbfilename reads an alternate partition database filename for partition configuration information filename must be an
absolute path and reside on a HFS file system. 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”. 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. -all | 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. | -auto | Boots all virtual partitions that
have their autoboot attribute flag set to AUTO. | | -b kernelpath | Boots the virtual partition
using the kernel kernelpath instead of
the default kernel | | -o boot_options | Boots the virtual partition
using the options boot_options, such as
-is for single-user mode or -lm for LVM maintenance mode. | -B hardware_path | Boots the virtual
partition using the disk device at the hardware_path | -D disk_index | (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. | | -E 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. |
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: MON> vparload -p winona2 -B 0.8.0.0.2.0 |
Note: -b kernelpath allows you to change the target kernel for only the next boot of partition_name. If you wish to make a permanent change
to the partition database, use the vparmodify command. For example, to change the partition database information so
that winona2 always boots using /stand/vmunix.other: # vparmodify -p winona2 -b /stand/vmunix.other See the vparmodify(1M) manpage for more information
on modifying the partition database. (vPars A.04.01) For 11i v2 (11.23) systems, alternate kernels
are in the directory /stand/alternate_config/. Also, when a virtual partition is booted, there may be a pause
in the console output. For more information, see “Booting a Virtual Partition”. Finally, when there is a pending Reboot for Reconfiguration
for the involved nPartition, the target virtual partitions will not
be booted until all the virtual partitions within the nPartition have
been shut down and the vPars Monitor rebooted. For more information
see “Shutting Down or Rebooting the nPartition (Or Rebooting the
vPars Monitor)”.
bootpath displays the device from which the vPars Monitor
(/stand/vpmon) was booted Example: MON>bootpath
disk(0.0.2.0.6.0) |
Displaying Information | |
cat filename [openonly] displays the contents of filename. When openonly is specified, this command
only prints "open succeeded" if the vPars
Monitor was able to open the filename.
This command is similar to the Unix cat command. filename must be a
text file on an HFS file system. /stand is the default directory Example: To display the file /stand/notes.txt MON> cat notes.txt
10/13/2001: built new kernel today. if problems arise, revert to saved kernel vmunix.original |
cbufpartition_name displays the contents of the console buffer of partition_name clear_pending clears a pending Reboot for Reconfiguration. If
there is a pending Reboot for Reconfiguration within the nPartition,
no virtual partitions can be rebooted until all the virtual partitions
within the given nPartition are shut down and the involved vPars Monitor
is rebooted. If Reboot for Reconfiguration has been set in error,
the clear_pending command clears it, enabling virtual
partition boots. help help or ? lists all vPars Monitor commands lifls lists the files in the LIF area getauto displays the contents of the AUTO file in the LIF area Example: MON> getauto
hpux /stand/vpmon |
log displays the contents, including warning and error
messages, of the vPars Monitor log. The vPars Monitor log holds up
to 16 KB of information in a circular log buffer. The information
is displayed in chronological order. ls [-alniFH] [directory] lists the contents of directory. This command is similar to the Unix ls command. directory must be on
a HFS file system. /stand is the default directory The ls command-line options
are the same as the Unix shell lsoptions. For detailed
explanations, see the ls(1M) manpage. In brief: | -a | all entries | | -l | long listing | | -n | numerical UIDs and GIDs | | -i | inode | | -F | appends a character after the entry, depending on the
file type, such as a / (slash) for a directory |
For example, to view the listing of files in winona2’s /stand directory: MON> ls /stand

monadmin controls the vPars flexible administrative capability
feature, as described in Chapter 11: “vPars Flexible Administrative Capability”. For usage information, see “monadmin”. scan lists all hardware discovered by the vPars Monitor
and indicates which virtual partition owns each device. settime [MM DD YYYY hh mm ss] sets the system's real time clock. Acceptable
date range is 1-1-1970 00:00:00 to 12-31-2034 23:59:59. threads controls the use of hyperthreading on servers
with dual core Intel Itanium processors. For usage information, see “CPU: Hyperthreading ON/OFF (HT ON/OFF)”. time displays system real time clock and OS time of
all the virtual partitions in GMT (Greenwich Mean Time). The OS time
displayed will consider the RTC and clock drift for the virtual partition.
However, if the partition is up, there may be difference in the OS
time displayed. toddriftreset resets the drifts of the real-time clock. Use
this command if you reset the real-time clock of the hard partition
at the BCH prompt. For brief information, see “Real-time clock (RTC)”. vparinfo[partition_name] This command is for HP internal use only.
