Listing Available nPartition Hardware Resources
This section presents how you can list all available hardware resources
in an nPartition server.
The following are common methods of listing available hardware:
• vparstatus -A lists the available processor, I/O, and memory
resources in the local nPartition. This command lists the hardware
that has not yet been assigned to any vPar.
Note that vparstatus -A command lists processors and I/O using a
form of the hardware path notation where a period (.) separates each
hardware path field rather than a slash (/).
• ioscan lists the assigned and active hardware in the local nPartition
or the current vPar.
When HP-UX is booted in a non-vPars environment, ioscan lists all
all active hardware in the local nPartition.
When HP-UX is booted in a vPar, ioscan lists only the I/O devices
assigned to the current vPar and lists processors on active cells in
the local nPartition (but it does not list bound processors in other
vPars).
Note that ioscan can list some processors that are not assigned to
the current vPar, including unbound processors assigned to other
vPars.
• mpsched -s lists only the assigned and active processors in the
current vPar or nPartition.
Note, however, that mpsched -s lists the HP-UX CPU IDs for
processors, not their hardware paths.
• parstatus -C lists the configurations of all cells in an HP
Superdome server complex, including the number of processors,
amount of memory, I/O chassis connections, current usage status,
and nPartition assignment.
Also refer to the chapter Listing and Managing Server Hardware on
page 307 for details.
