HP Superdome 2 Partitioning Administrator Guide (5900-2540, December 2012)

provides the rootport to ioslot mapping for the I/O resources in an I/O bay. Rootports and ioslots
have a one-to-one mapping and either of them can be used to assign I/O to a vPar. The rootport
(RP) or ioslot is specified in the resource path format. Typically disk devices or LAN devices get
attached to a rootport. On blades, iLO is also off a rootport.
Assigning I/O at the rootport or I/O slot Level
You can run the vparcreate and vparmodify commands with either of these parameters:
rootport resourcepath format: -a io:9/1/0/0/2
or
ioslot resource path format: -a ioslot:9/1/3
A vPartition may be created at the OA with the following command:
vparcreate -N5 –p1 -a cpu::4 -a mem::6000 -a ioslot:9/1/3
To verify that the created vPar had the expected IO in that slot, you can check using efi (info io),
and then run ioscan -m resourcepath once the OS has booted. It searches for the ioslot
number:
# ioscan -m resourcepath | grep 9/1/3
48/0/0/2/0/0 0x90001000203ff85 ioslot-9/1/3
To get the IO details, this result is used in a second call to ioscan.
# ioscan -kf -H 48/0/0/2/0

The rootport is associated with the I/O slot hosting the PCIe port. Table 8 (page 91) displays the
I/O hierarchy:
