HP-UX Virtual Partitions

HP-UX Virtual Partitions (vPars) A.05.01 enables multiple instances of the HP-UX 11i v3 Operating Environment (OE) to run simultaneously on one server or within one nPartition, with each OE instance hosting its own set of applications in a isolated environment.

Summary of Change

What’s New for Customers Migrating from HP-UX 11i v1 September 2005?

vPars A.05.01 includes the following additions to the current vPars features:

online memory migration
mixing A.04.02 and A.05.01 virtual partitions in the same vPars environment
support for hyperthreading on CPUs and OSs that support hyperthreading
ability to cancel pending CPU and memory migrations




	NOTE: Mass Storage Stack Formats. Although the new mass storage stack formats (SCSI-3 formats, virtual hardware path format, and the new device special file formats) are supported within the HP-UX 11i v3 OS virtual partitions, they are not supported for use on the vPars command line or vPars stdout/stderr. You should continue to use the legacy ioscan 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. However, wherever the new formats are supported by other HP-UX 11i v3 HP-UX commands and tools, you can use these new formats within the virtual partitions running HP-UX 11i v3. For information on using the new mass storage stack formats, multipathing, and agile addressing, see the whitepaper The Next Generation Mass Storage Stack and the manual HP-UX System Administrator's Guide, available at `http://docs.hp.com`.
