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 Monitor command scan.

Monitor: Using Monitor Commands
You can use the following Monitor commands at the Monitor prompt for booting and basic
troubleshooting. However, most vPars operations should be performed using the vPars shell
commands.
Note the following for the Monitor commands:
• Unless specifically stated, all operations occur only on the boot disk from which the Monitor
was booted. Usually, this is the boot disk of the primary path entry in system-wide stable
storage.
Further, the 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
Monitor commands.
• The following Monitor commands are disabled when one or more virtual partitions are up:
— getauto, lifls, and readdb.
• The following Monitor commands are disabled when the virtual partition that owns the
disk from which the Monitor was booted, usually the primary path, is up:
— ls and cat.
NOTE: You can see all the latest Monitor commands and options from the vpmon(5) manpage.
Not all Monitor commands are available on all platforms. The following common 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 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 “Monitor: Booting the vPars
Monitor” (page 126).
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,
