1. A customer has several AS/400 servers in their IT infrastructure running V5R2 that they wish to

consolidate. The customer wants to simplify their environment and install i5/OS on a p5 590 with 16

1.65GHz processors and 20 i5/OS partitions. The customer plans to use the Advanced Power

Virtualization to share their storage, processors, and memory. What considerations and limitations should be reviewed with the customer before the purchase?
A.Resources cannot be shared with an i5 partition when it is put on a pSeries. The i5 partition needs its

own 9411100 tower because of IOP. V5R3 OS or later is required. There is a maximum of two partitions

in a 590.

B.Resources cannot be shared between partitions when i5/OS is put on a pSeries. The i5 partition needs

its own 9411100 tower because of IOP. i5/OS can be at V5R2 or a V5R3. Currently only one i5 partition is allowed.
C.V5R3 is required for the i5 partitions. Virtual IO Server is not supported for the i5/OS partitions to share storage. Up to 10 i5 partitions per processor are allowed (a maximum of two processors for up to 20 partitions).
D.Processor and memory resources can be shared between AIX 5L, Linux and i5/os partitions. i5/OS

needs to be at V5R3, and Virtual IO Server is not supported for the i5/OS partition to share storage. On a

1.65 GHz POWER5 p5 590 there is a maximum of one partition. Answer: C

2. A customer wants to use Virtual SCSI disks to boot multiple operating systems from the same disk. How will the volumes appear in the Virtual IO Server and how will the logical volumes appear in the partition?
A.The Virtual SCSI disks are defined as logical volumes in the Virtual IO Server. The logical volumes

appear as real devices (hdisks) in the client partitions.

B.The Virtual IO adapters are connected to a virtual host bridge. On the Virtual IO Server they are vdisks,

on the client partition, the exported disks are visible as virtual disks.

C.The Virtual SCSI disks are represented in the ODM as a bus device whose parent is sysplanar0.

Logical volumes will be assigned to the Virtual IO Server and virtual disks, vdisks, in the client partition. D.The Virtual IO adapters are represented as adapter devices with the virtual host bridge as their parent.

On the Virtual IO Server they are vdisks attached to vscsi, on the client partition the exported disks are

visible as virtual disks. Answer: A
