HP-UX Virtual Partitions Administrator Guide (includes A.05.09) (5900-2188, March 2012)

NOTE: The default memory assigned to a virtual partition is 0 MB, so you need to specify enough
memory for your applications and the operating system. While there is no specific minimum base
memory requirement per vPar, the HPUX kernel does require a certain amount of base memory to
boot successfully. For this reason, we currently recommend that 1 GB of base memory is assigned
per vpar. The more base memory a virtual partition has, the better the performance will be. This
is especially true of applications that require large amounts of locked memory. See the Installation
and Update Guide for your OS and the nPartition Administrator’s Guide.
In our examples, we will use the following sizes:
keira3keira2keira1Partition Name
1024 MB1024 MB1024 MB
Memory
winona3winona2winona1Partition Name
1280 MB1280 MB1024 MB

I/O
For detailed information on I/O Assignments, see “I/O: Allocation Notes” (page 202).
For simplified I/O block diagrams of the LBA to physical slot relationship of PA-RISC systems, see
Appendix A (page 273).
Assigning I/O at the LBA Level
Looking at the full ioscan output to verify that we have the desired I/O for each virtual partition,
we will assign the I/O at the LBA level. (When assigning hardware at the LBA level to a partition,
all hardware at and below the specified LBA is assigned to the partition.)
For our example non-cellular (winona) and cellular (keira) systems , the ioscan output shows the
LBAs as:
keira# ioscan -k | grep "Bus Adapter"
0/0/0 ba Local PCI Bus Adapter (782)
0/0/1 ba Local PCI-X Bus Adapter (783)
0/0/2 ba Local PCI-X Bus Adapter (783)

0/0/6 ba Local PCI-X Bus Adapter (783)
