vPar Provider
The HP-UX Virtual Partitions (vPars) product allows division of a server into multiple
virtual partitions, which is used to run multiple instances of HP-UX. Each virtual
partition has its own hardware resources (CPU, Memory and I/O slots).
The vPar Provider is an HP-UX WBEM services provider introduced in the HP-UX 11i
v2 May 2005 release for extracting information about virtual partitions on a system. As
it is a read-only provider, clients cannot modify virtual partition configurations with it
and have to use a WBEM interface instead.
The vPar Provider always gets its data from the default vPar database located at
/stand/vpdb. The vPar Provider talks to the nPartition Provider to get information
about I/O assigned to a virtual partition. It then determines whether or not it is running
on an nPar. If the nPartition Provider is down, then the information is not provided. The
vPar Provider uses the namespace root/cimv2/vpar.
Summary of Change
The vPar Provider has the following features:
• It is a WBEM vPar Provider, which displays information about virtual partitions.
• Clients cannot modify virtual partition configurations with it, as it is a read-only
provider.
