Note that specifying the max_vpars value helps the system reserve only the needed amount of

memory to manage the runtime needs of firmware. When that is not specified, the system defaults

to a max_vpars of 16. This explains the difference in the available vPar assignable ILM in the

previous examples.

If size is not an integral multiple of the granularity of the specified memory type, vPars normally

adjusts it upward to the next granule boundary.

In a vPar environment, either of the above command-line options allows the system to reserve the

available indicated memory. Thus, it is possible to define vPars with more memory than nPartition.

Actual memory ranges are only assigned to the vPar when it is booted. The memory ranges might

vary for every boot sequence.

I/O

The vPar assignable IO resources are rootports or ioslots in the blades and I/O bays. Each I/O

bay consists of an iohub, which is the chip that supports up to three root complexes. The rootports

live under a root complex. Each root complex supports two rootports, providing a total of up to

six PCIe slots per iobay. The iohub and root complex are elements in the I/O hierarchy leading

upto the rootport in a BIOX. However, vPar assignable resources occur at the rootport level, with

the iohub and root complex included in the resourcepath leading upto it. Rootports and ioslots are

the ways of representing I/O resources. The

parstatus -c enclosure#/blade# -V command provides the rootport to ioslot mapping

for the I/O resources on a blade. Similarly, the parstatus -i IOX#/IObay# -V command
