Mixed HP-UX 11i v2/v3 vPars Environments in vPars A.05.xx
Beginning with vPars A.05.01, you can have a mixed HP-UX 11i v2/v3 vPars environment. A mixed HP-UX
11i v2/v3 vPars environment allows you to have a vPars A.05.01 monitor and database that supports both
virtual partitions running vPars A.05.01 on HP-UX 11i v3 (11.31) and virtual partitions running vPars
A.04.02 or later on HP-UX 11i v2 (11.23). An example mixed HP-UX 11i v2/v3 vPars environment looks like
the following:
Note that mixed HP-UX 11i v2/v3 vPars does not refer to mixing hardware (PA and Integrity) platforms.
Additionally, virtual partitions running vPars A.03.xx on HP-UX 11iv1 (11.11) and vPars A.04.01 on HP-UX
11i v2 (11.23) are not supported in a mixed HP-UX 11i v2/v3 vPars environment.
NOTE Please read the following rules and the table below when running a mixed HP-UX 11i v2/v3
vPars environment. Many of the features of vPars are version-specific.
To switch to an environment of only virtual partitions running vPars A.04.xx on HP-UX 11i v2,
shut down the A.05.01 Monitor and boot up the A.04.xx Monitor.
Features
The following features work from all virtual partitions:
• legacy vPars functions
this includes dynamic CPU migration, except where noted below.
• HP-UX functions
all the corresponding HP-UX features associated with an HP-UX 11i release continue to work. Note that,
as in a normal OS instance, an 11.31-only feature will not work in an 11.23 OS-instance.
• HT OFF
all virtual partitions can boot and run when hyperthreading is disabled (HT is set to OFF).
The following features can be executed only from the vPars-A.05.01/11.31-OS virtual partitions:
• creation, removal, and modification of a target virtual partition.
The vparcreate and vparremove operations can only be performed from the vPars A.05.01/11.31-OS
virtual partitions; vparmodify operations affecting other virtual partitions can only be performed from
the vPars A.05.01/11.31-OS virtual partitions.
