Resource Migration and Required States
The table below shows whether a resource is dynamically migratable; in other words, for each given resource
type and vPars version, the intersecting box shows whether the target virtual partition must be up or down to
migrate the resource.
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.
Table 2-3 To Migrate the Resource, the Target Virtual Partition State must be...
Version CPUs Memory I/O
A.03.xx bound: down
unbound: up or down down
down
A.04.xx
boot processor: down
all others: up or down
A.05.xx float: up or down
base: add: up or down
delete: down
