A customer is planning to migrate an existing AIX 7 environment from POWER5 hardware to POWER7. The existing deployment consists of multiple machines, each hosting many LPARs. Due to software licensing constraints, the new environment must maintain the same number of logical CPUs. The pmcycles command reports the following on an LPAR on the POWER5 environment:
$ pmcycles -m CPU 0 runs at 2198 MHz CPU 1 runs at 2198 MHz CPU 2 runs at 2198 MHz CPU 3 runs at 2198 MHz CPU 4 runs at 2198 MHz CPU 5 runs at 2198 MHz CPU 6 runs at 2198 MHz CPU 7 runs at 2198 MHz
How many virtual CPUs should be assigned to the destination LPAR on the POWER7 environment?

When planning a new Power 770 system, how can an administrator ensure that a database LPAR is prevented from sharing processors with any Multiple Shared-Processor Pools, regardless of whether the LPAR is active?

The VIO servers in a Power Systems server have already been installed and the LUNs have been mapped to their vhosts as virtual scsi disks. When defining a client LPAR, the administrator wants to map a virtual client SCSI adapter to a server adapter in one of the VIO servers.
In the "Create Virtual SCSI Adapter" dialog box below, why are the fields for "Backing Device" and "Client Disks" empty?

As a result of an acquisition, an administrator is planning to consolidate some single-LPAR POWER6 520 servers onto an existing POWER7 server.
The administrator is attempting to make these 520 systems HMC-managed.
The network connection between the 520 system and an existing operational HMC have been verified and checked. However the POWER6 machines fail to appear on the HMC panels.
What is the most likely resolution for this issue?

A production application is hosted across two Power 750 Express servers, managed by an HMC. Each machine has 16 cores and 32GB RAM. Four 8GB LPARs are defined across the two systems and only 3 LPARs are active at once. Live Partition Mobility is used to maintain availability when maintenance is required.
A test environment is being built across two Power 550 Express servers.
Each machine has 8 cores and 16GB RAM. Four 4GB LPARs will be defined across the two systems, again only 3 will be active at once. To isolate the test and production environment, the test environment is managed by two IVMs.
Two LPARs have been created on each test server. The administrator initiates a Live Partition Mobility operation to test moving LPARs between the servers.
The migrlpar command fails to migrate the 4th LPAR with the following error:
"The target managed system does not have enough available memory to create the partition."
Because the 4th LPAR was inactive, it was expected that an inactive migration would be successful.
Why would this inactive migration fail on the test environment, but succeed on the production environment?

A redundant pair of VIO Servers is used to virtualize the same SAN LUNs to a number of AIX LPARs. To ensure that Multipath 10 is correctly configured an administrator sets the appropriate device attributes on the vSCSI disks on the clients.
One of the VIO Servers was shut down for 5 minutes to simulate a failure. After the VIO Server was brought back online, the administrator found that some LPARs recovered their storage paths automatically, yet some LPARs did not recover their paths at all.
How can the administrator recover from the lack of path recovery?
