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?

What Shared Ethernet Adapter environment can be implemented to prevent client network
outages when the Virtual I/O server needs to be shut down for maintenance?

An administrator is planning to deploy multiple AIX LPARs onto a Power 770. These LPARs will be
served with Virtual SCSI storage from a pair of VIO Servers (VIOS). What consideration should be
considered with regard to VIOS configuration to ensure suitable performance of the virtualized
storage?

A customer has a VIO server which runs on internal disks. It can not support an outage during
normal business hours. Which action can the administrator take that will support this requirement
AND improve overall system availability?

An administrator is trying to perform Live Partition Mobility (LPM) between physical systems
managed by the same HMC. The VIO Servers (VIOS) on each physical system are connected to
the same SAN. The client LPARs will use virtual SCSI (vSCSI) disks. The SCSI adapter slot
numbers are between 11 and 20.Each client LPAR has a unique name. The network used by the
client LPARs use Logical Host Ethernet adapters (LHEA).The PowerVM Enterprise edition is being
used. No EtherChannel has been configured. Why are LPM activities failing?

A partition that uses an LHEA for network connectivity needs to be moved to another managed
system. The administrator has the LHEA configured in an Etherchannel with a virtual Ethernet

adapter as the backup adapter. When attempting to perform the migration using the Migration
Wizard, it fails. What is necessary for the migration to be successful?

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?

Which of the following are advantages of configuring a management IP address on a VIO Server?

An administrator has installed a Linux LPAR using virtual storage and virtual networking on a
POWER7 system and is attempting to DLPAR additional memory into the LPAR. They see the
following error message during the DLPAR operation.

Which action will resolve this issue?

When planning for virtual disk redundancy on an AIX LPAR, which solution would provide the
highest availability?
