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

• A.03.xx and earlier: When the system monarch CPU is not owned by any virtual partition,
you will also see the vPars Monitor prompt MON> while toggling among the virtual consoles.
A monarch CPU exists in both non-vPars and vPars servers. After a server is powered-on, the
monarch CPU determines what other CPUs are configured in the server and then launches 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.
• A.04.xx and A.05.xx: When any CPU is available, you will see the MON> prompt.
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.
