There are three Power Systems servers with redundant FSPs, and two HMCs. One HMC is in the data center while the second is in operations. Each HMC is connected to its own private network and each of the three systems are connected to both HMCs.
Two of the Power Systems servers and the HMC in the data center have been moved across the room. They have been reconnected to the HMC network, and power has been applied to the HMC and the first server. On the data center HMC the server shows up twice, once with "Authentication failed" and the second with "no connection." Connecting to ASM yields "incorrect password" on the first instance, but works on the second instance.
What the most likely cause?
An optical drive is owned by a VIO Server and shared between multiple IBM i partitions as virtual optical devices.
An administrator wants to use the virtual optical device on an IBM i partition, but WRKHDWRSC *STG shows that the virtual IOP is "Inoperative."
After verifying that the device is correctly allocated to the partition, what action should be taken?
A Power 720 administrator is going to create a new partition on a machine with 3 existing partitions. The machine has 2 processors in a Shared Processor Pool. The three partitions as defined below for their processor requirements are active, utilizing the Desired processing units.

What is the effect of configuring partition LPAR4 as follows using the same processor pool?

An IBM i 7.1 partition hosts another IBM i 7.1 partition. The hosting partition provides disk and networking services for the client partition.
An operator restarts the host partition from the HMC.
What happens to the client partition?
What is the tool used to aid in upgrade planning for interdependencies of HMC and system firmware upgrades?
An administrator is planning to update a POWER blade server managed with Integrated Virtualization Manager (IVM) from version 1.5 to version 2.2
What should the administrator take into consideration?
A company requires up to 20 client IBM i partitions. Each must have redundant access to SAN storage and minimal hardware in the POWER7 system.
Which option will support this?
What minimum hardware and software levels are required to host IBM i on other IBM i partitions?
