An administrator has removed a client LPAR and would like to unmap the virtual Fibre Channel

adapter vfchost0 from the physical backing adapter fcs2.
Which of the following commands will achieve this?

CORRECT TEXT
An administrator adds a new virtual target device to a vhost adapter that already had target
devices on it. The client LPAR does not detect the new disk and the following error has been
logged in the errlog:
IDENTIFIER: DF63A4FE
Date/Time: Tue Mar 8 10:41:55 2011
Sequence Number 2205
Machine Id: 00C7654DB00
Node Id: vios1p1
Class: S
Type: TEMP
Resource Name: vhost3
Description
Virtual SCSI Host Adapter detected an error
Probable Causes
Virtual SCSI Host Adapter Driver is an Undefined State
Failure Causes
Virtual SCSI Host Adapter Driver is an Undefined State Recommended Actions
Remove Virtual SCSI Host Adapter Instance, then Configure the same instance

What is the most likely cause for this situation?

A new virtual SCSI adapter has been added to a SuSE Linux client using DLPAR. By what method
will the adapter be added to the system?

An administrator is attempting to remove a virtual adapter from an AIX partition using an HMC
running V7R7.2. The DLPAR operation is failing with the following message:
“Virtual adapters that are marked as required cannot be dynamically removed from the partition.
Please change your adapter selections and try the operation again.”
How can the administrator remove the virtual adapter while minimizing any downtime?

An administrator wants to add vSCSI adapters to a new client using the existing mapping schema.

The slots will be 40/41 on the VIO Server. Given the current properties of the VIO server, what
must be done to accomplish this?

An administrator has an application running in a WPAR on a Power 720. The application must be
migrated to another server. What is the minimum required hardware level for this to work?

What is required on the Global Environment for Live Application Mobility to function?

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 LPAR was created on a POWER6 system with default processor/memory settings. It was
migrated from the POWER6 system to a POWER7 system. Over time, that LPAR has been
shutdown and restarted.
An administrator now needs to migrate the LPAR back to the POWER6 system, but it fails to
validate.
There have been no changes in the LPAR profile, network, or in the SAN configuration.
Which action will enable the operation to complete successfully?

Given the following lspath command output from an LPAR, what is the most likely reason for the
current situation?
