the other CPUs to create a multi-CPU server. Typically, the CPU with the lowest numbered
hardware path address (belonging to the core cell for nPartitionable systems) is the monarch
CPU. To see the lowest numbered hardware path, on a non-vPars server use ioscan, or on
a vPars server use the vPars Monitor command scan.

vPars Monitor: Using vPars Monitor Commands
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:
— ls and cat.
NOTE: You can see all the latest vPars Monitor commands and options from the vpmon(5)
manpage.
Not all vPars Monitor commands are available on all platforms. The following common vPars
Monitor commands are not available on Integrity systems: cat, cbuf, getauto, lifls, and
ls. Refer to the vpmon(5) manpage for a complete list.
Booting
• 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” (page 132).
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
