In addition to providing the resource information, the parstatus command displays the existing
nPartitions.
Assigned or unassigned blades and I/O bays
Each blade in a server complex is either assigned to one of the nPartitions in the complex, or
unassigned. If a blade or an I/O bay is unassigned, it is not used by any nPartition. Blades and
I/O bays that are unassigned are considered to be available resources; they can be assigned to
any of the existing nPartitions, or can be used to create new nPartitions.
You can assign a blade to an nPartition or unassign a blade from the nPartition using the
parcreate or the parmodify commands. For more information, see help parcreate and
help parmodify.
Active and inactive blades
Blades that are assigned to an nPartition and have been booted are active blades whose resources
(processors, memory, and on-board I/O) can be actively used by software running in the nPartition.
Blades that are Inactive are either not assigned to an nPartition (recognized by the empty Par
Num field against the blades in the parstatus command output) or are assigned to an nPartition
that is not yet powered on (partition status Inactive/DOWN in the parstatus command output).
Blades assigned to an nPartition are powered only when the partition to which they are assigned
are powered on or activated. A blade might show up as Inactive while being part of an nPartition
that has been powered on, if the user has set the use_on_next_boot attribute of the blade to
be false.
I/O Enclosures and I/O bays
HP Superdome 2 I/O expansion enclosures (IOX enclosures) contain two bays, each of which can
be independently assigned to nPartitions. I/O bays are not directly attached to blades on HP
Superdome 2 servers. The I/O bays in an IOX can be assigned to any nPartition, thus allowing
more flexible I/O assignments. The resource path format to specify an I/O bay is
IO_enclosure#/iobay#. I/O bays are assigned using the -a
io:enclosure#/iobay#:[use_on_next_boot] option of the parcreate and parmodify
commands.
