HP-UX Virtual Partitions Release Notes (A.05.01)

Read Before Installing
Mixed HP-UX 11i v2/v3 vPars Environments in vPars A.05.xx
Chapter 2 15
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.
Note that this only applies to performing these operations on other virtual partitions.
Operations where the source and target virtual partition are the same are always
supported, regardless of whether you are in a mixed HP-UX 11i v2/v3 vPars environment
or not.
When the flexible administrative capability is ON, setting the vPars A.04.xx/11.23-OS
virtual partitions as the only designated-admin virtual partitions is not recommended. If
all the designated-admin virtual partitions are vPars A.04.xx/11.23-OS virtual partitions,
no partitions will be able to perform vparmodify, vparremove,orvparcreate operations
on other partitions.
The following features work only between the vPars-A.05.01/11.31-OS virtual partitions:
• dynamic memory migration
In a mixed HP-UX 11i v2/v3 vPars environment, dynamic memory migration is only
supported on the vPars versions that support dynamic memory migration. In other words,
the source and target virtual partitions must be running vPars A.05.xx.
