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?

An architect is considering whether to specify vSCSI or NPIV for the rootvg disks in a new virtualized environment. Storage is to be provided by an IBM San Volume Controller (SVC) and controlled using SDDPCM.
Which of the following is an advantage of using vSCSI technology instead of NPIV?

An architect is looking at the implications of uncapped weights for a new POWER7 system. The system will consist of four uncapped logical partitions with the following weightings:
Assuming all partitions have equal entitlement and virtual processor configurations in the partition profiles, and request additional resources from the shared processor pool over a period of 1000 cycles, how many cycles will be allocated to LPAR B?

A VIO server administrator is configuring MPIO-based storage for a new LPAR named P7_3_AIX.The administrator runs the lspv -free command and sees 4 disks free. The lsmap -all command confirms that the disks are free. A check of the list of LPARs shows the following: In order to avoid problems, what else should be verified before mapping storage to the new LPAR?
Correct Answer: A

While reactivating client LPARs following a scheduled power down, some LPARs have lost visibility to their NPIV-allocated SAN LUNs. On investigation it appears the WWNs have changed on the problem LPARs. What is the most likely cause for the change in WWN?
