Table 2-3 To Migrate the Resource, the Target Virtual Partition State must be...

The table below shows the same information, but from the perspective of dynamic migration (in
other words, online migration):

NOTE: 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,
memory migration operations can be initiated only from virtual partitions running vPars A.05.xx,
and the virtual partition target for the memory migration must be running vPars A.05.xx as well.
Transitioning from vPars A.03.xx to vPars A.04.xx/A.05.xx (CPU Syntax
and Rules)
The values in a vPars database that were created using vPars A.03.xx and ported to vPars A.04.xx
will have the following A.04.xx meanings for those values; likewise, using vPars A.03.xx syntax
on a vPars A.04.xx system has the following A.04.xx meanings.
This table summarizes the A.04.xx and A.05.xx CPU syntax and rules

cpu:::min
• minimum number of CPUs assigned to the partition
• cannot change min while virtual partition is up
cpu:::min
• number of bound CPUs
• minimum number of CPUs assigned to the partition
• number of CPUs assigned by hardware path is subset
of min
• cannot change min while virtual partition is up
cpu:hw_path
• specify CPU by hardware path
• when a virtual partition is down, the number of CPUs
assigned by hardware path must be less than or equal
to the pre-existing total setting
• on dual-core processor systems, hw_path refers to the
CPU cores (see ioscan(1M))
cpu:hw_path
• specify CPU by hardware path
• number of CPUs assigned by hardware path is subset
of min
