HP-UX Virtual Partitions Administrator's Guide (includes A.03.05 and A.04.05)

Memory
For detailed information on memory allocation, read “Memory: Allocation Notes” (page 226). If
you are planning an A.05 system, you should also see “Memory: Topics” (page 177).
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 Install and Upgrade Guide for your OS and the nPartition Administrator’s
Guide for your server
In our examples, we will use the following sizes:
keira3keira2keira1Partition Name
1024 MB1024 MB1024 MB

winona3winona2winona1Partition Name
1280 MB1280 MB1024 MB

I/O
For detailed information on I/O Assignments, see “I/O: Allocation Notes” (page 213).
For simplified I/O block diagrams of the LBA to physical slot relationship of PA-RISC systems,
see Appendix A (page 299).
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 servers, 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)
0/0/4 ba Local PCI-X Bus Adapter (783)
0/0/6 ba Local PCI-X Bus Adapter (783)
0/0/8 ba Local PCI-X Bus Adapter (783)
