HP-UX Virtual Partitions Administrator Guide (includes A.05.08) (5900-1312, March 2011)

access memory. Therefore, enhancing the performance significantly for vPars on multi-cell Integrity
systems. With LORA enabled, an administrator or a user can configure vPars using the vparcreate
command along with CPU by count, and Cell Local Memory (CLM). Also, specifying the I/O card
from the same cell as that of memory further enhances the system performance. For more information
on LORA, see http://h20000.www2.hp.com/bc/docs/support/SupportManual/c02070810/
c02070810.pdf. The following sections discuss how LORA guidelines are implemented on vPars.
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.

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://h20000.www2.hp.com/
bc/docs/support/SupportManual/c02070810/c02070810.pdf.
