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.
NOTE: There are some I/O slots on the blade itself. These are two dual-port LAN on Motherboard
modules (LoMs), three mezzanine card slots, and the iLO port of the blade. The mezzanine slots
are assigned slot numbers 1, 2, and 3. The LoMs are assigned slot numbers 4 and 5. The iLO is
assigned slot number 7. The mezzanine cards are not supported at the first release. If the I/O on
the blade is not sufficient for the nPartition, assign additional I/O using the IO Bays.

Finding the resource path of I/O

Use the OA CLI or UEFI Shell commands to locate the resource path of your blade-based I/O
components and I/O bay-based I/O slots. Using the HP Superdome 2 OA, run the parstatus
c {enclosure#/blade#}
reports the path of the LoMs on blade 2 in enclosure 1. Using the UEFI shell, the info io command
returns all of the resource paths to all I/O. The following is a sample output of the info io
command for a dual ported LoM (enclosure 1, blade 2, I/O slot 5):
1/2/5 04/80 00/00 14E4/1650 103C/7105/00 Network Controller - Ethernet control
1/2/5 04/80 00/01 14E4/1650 103C/7105/00 Network Controller - Ethernet control
For the same LoMs, the resource path listing that uses the parstatus -c1/2 is shown below.
LAN on Motherboard NICs are numbered 4 and 5:
