Whenever you're doing installations or migrations it's a good idea to work
with the physical address of the rootvg disk(s).
In your case, that's 10-60-00-9,0 and 10-60-00-8,0.
When the system does it's device discovery, which it does afresh for a
migration, it will find ~8,0 first and so that will get called hdisk0. At
this point, the ODM is not available.
I guess that at some point in the past you've added or replaced a disk in
this system, so originally ~-9,0 was the first disk in the system.
You should be safe to continue, using hdisk1 (~-9,0, which is the important
thing). Afterwards, I'm not sure whether it will continue to appear as
hdisk1 or will then be seen as hdisk0, when the ODM is available again.
