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

• top and other applications that show CPU ID
The CPU ID displayed by the top command and other applications may not be indicative of
the actual CPU index in standalone or nPars mode, nor of the actual hardware path. Within
a virtual partition, top sees only the CPUs assigned to it. Possible top output is shown below;
the CPU index is the left-most column.

• Agile view of Mass Storage
The agile view of mass storage introduced in HP-UX 11i v3 (11.31) is supported with vPars.
Support for agile addressing vPars configurations and operations is provided starting with
vPars A.05.03. In the vPars A.05.01 and vPars A.05.02 releases, only the legacy hardware
path format is supported.
◦ The vPars A.05.03 release includes support for the next-generation mass storage subsystem
in HP-UX 11i v3 (including agile addressing). In the next-generation mass storage
subsystem, support has been extended to include vPars configurations and operations
starting with vPars A.05.03.
Agile addressing support is only provided for lunpath hardware paths, not for LUN
hardware paths. Use of LUN hardware paths will result in an error.
Agile addressing is supported only for HP-UX 11iv3 (11.31) releases of vPars, starting
with vPars A.05.03. It is not supported by vPars A.05.02 or earlier, vPars A.04.xx on
HP-UX 11i v2 (11.23), or vPars A.03.xx on HP-UX 11i v1 (11.11). This restriction also
applies to mixed HP-UX 11i v1/v2/v3 vPars environments. Virtual partitions running
HP-UX 11i v1 or HP-UX 11i v2 do not support agile addressing.
◦ In the vPars A.05.01 and vPars A.05.02 releases, the lunpath hardware path format and
LUN hardware path format are not supported for use on the vPars command line, and
vPars commands will only use legacy hardware paths in their output. You must continue
to use the legacy hardware path format that existed in previous vPars releases when using
the vPars commands; for HP-UX 11i v3 (11.31), ioscan’s default output will continue
to show the legacy format.
vPars does not affect the use of the agile view with non-vPars commands. Wherever the
new formats are supported by other HP-UX commands and tools, you can use these new
formats within the virtual partitions running HP-UX 11i v3 (11.31).
vPars does not support disabling legacy mode.
For information on the agile view of mass storage, including the new hardware paths, device
special files, and legacy mode, go to the BSC website at www.hp.com/go/hpux-core-docs,
