RE: LPARing an 810......

["Wilt, Charles" <CWilt@xxxxxxxxxxxx>]

Nope, for an OS/400 partition you have two choices:

Bus-level partition
IOP-level partition

So either everything on a bus belongs to one partition  or everything
under an IOP (1-4 IOA cards) belongs to one partition or another.

If you're doing IOP level, that means that the bus is shared.  You can
have a IOP with attached IOA's that are switchable between partitions.
For example, in my 810 I have 2844 IOP with a 5702 Tape IOA that is
switchable; which lets me use tape drive attached to the 5702 on either
partition.  Note that only one partition can own/see/use the tape drive
at a time.

DASD and its controllers can _NOT_ be switch.  You have to have at least
one dedicated IOP, with at least a DASD controller and a console
connection for each LPAR.
