HP-UX Virtual Partitions Administrator Guide (includes A.05.07) (5900-1229, September 2010)

Prerequisite
To enable LORA support, ensure that you install the following:
• HP-UX 11i v3 March 2009 with Update 4
• vPars A.05.05
NOTE: If you are updating to vPars A.05.05 from any existing vPars version, ensure that
you recreate the database and boot with the vPars A.05.05 monitor.
Configuring vPars for LORA Support
To configure vPars for LORA support, complete the following steps:
1. Install vPar A.05.05 on all the vPar disks.
2. Create the vPar database in nPar mode.
CAUTION: Do not assign CPUs by path or CLPs in order to benefit from LORA support.
For more information, see “Planning Your Virtual Partitions based on LORA Guidelines”
(page 66).
Planning Your Virtual Partitions based on LORA Guidelines
The following table shows a sample multi-cell Integrity system with the resource information.
Table 3-8 Resource Availability on a Multi-Cell Integrity System
Available ResourceResource
80 GBMemory
24 CPUs (Cell 0 with 8 CPUs, Cell 1 with 8 CPUs, Cell 2 with 8 CPUs)CPU cores
4 (1 in Cell 0 + 1 in Cell 1 + 2 in Cell 2)IO cards

In order to implement LORA guidelines on a multi-cell Integrity system, you must allocate 1/8th
of the total memory as Interleaved Memory (ILM) and 7/8th of the total memory as Cell Local
Memory (CLM). For more information on implementing LORA in nPars, see http://docs.hp.com/
en/14655/ENW-LORA-TW.pdf.
The following figure shows a multi-cell Integrity system with memory allocation recommendation
to implement LORA guidelines.
