What is a prerequisite for Live Partition Mobility?

After enabling 16 MB memory pages, a customer determined that more memory was
needed for nightly batch jobs. The customer decided to use Active Memory Sharing (AMS)
to dynamically adjust memory usage between LPARs on the system. What must the
customer consider before implementing Active Memory Sharing (AMS)?

An administrator installed a new HMC and connected several managed systems to it.
According to company policy the open network, used for user access to HMC, should be
firewalled. Which service must be permitted through the firewall to enable DLPAR
operations?

A customer uses NIM for OS and software deployment on 64 LPARs divided into three
groups: development, test and production. What is the quickest way to install fixes on the
test servers only?

An administrator tries to start an LPAR, but it stalls without any diagnostic LED code shown
on HMC. The administrator wants to review last LED codes, which were shown. Which of the
following HMC commands will show the codes?

A Power 770 is running in a dual VIO Server (VIOS) environment with Active Memory
Sharing configured. There are two shared memory partitions. The managed server is called
FRED.LPAR_1 is using VIOS1 as the paging VIOS partition.LPAR_2 is using VIOS2 as the
paging VIOS partition.VIOS1 had been rebooted, so a failover to VIOS2 has occurred. How
would the administrator failback paging VIOS partition LPAR_1 back to VIOS1?

A VIO Server is installed on the mirrored disks hdisk0 and hdisk1. During an update the VIO
Server crashed. After rebooting, the administrator detects that hdisk1 is broken. The
administrator decided to restore a previously made backup from the NIM server, and

removed the damaged hdisk1.What step is required to restore the VIO Server on only hdisk0
from the NIM Server?

An administrator updated tunable virtual memory parameters using vmo -p. When the
system was rebooted the tuning was lost. Which of the following is the most likely reason?

A regional data center has experienced a disaster requiring the shared-processor LPARs
running AIX on Power servers to be temporarily restored to Power servers in the disaster
recovery data center (DRDC). The administrator has been asked to prepare an estimate of
the number of cores that will need to be activated via Capacity on Demand on the target DR
systems. The administrator has access to recently-collected vmstat data for each of the
LPARs as well as the hardware configuration of the servers that hosted the LPARS, but
does not have access to the individual LPAR profile configurations. Which of the following
CPU elements from the vmstat output will allow the administrator to make an estimation of
the core activation requirements?

An administrator is attempting to diagnose a reported performance issue within a volume
group. When trying to use the lvmstat command against a logical volume within the volume
group, the following error is reported :0516-1309 lvmstat: Statistics collection is not enabled
for this logical device. The administrator does not want to enable collection across the whole
volume group. How can collection be enabled on a single logical volume?
