IBM Virtualization Technical Support for AIX and Linux - v2 Sample Questions:

1. How can an existing AIX 5.2 LPAR, which is using SAN storage, be migrated into a versioned WPAR (Workload Partition)?

A) Rezone the SAN storage and use NPIV.
B) Using LPM, but downtime will be required.
C) Backup and restore a mksysb.
D) Dynamically using LAM.

2. While trying to reject recent updates to the VIOS, an administrator received an error message stating that a file set may not be rejected because a dependent file set is committed.
Which command can be used to overcome this error?

A) updateios -remove <committed_fileset_name>
B) updateios -commit -u <committed_fileset_name>
C) updateios -cleanup <committed_fileset_name>
D) updateios -reject-f <committed_fileset_name>

3. 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?

A) Reduce the number of paths to the LUNS to 6 or less.
B) Reboot the client LPARs.
C) Allocate both vSCSI adapters to the client LPARs.
D) Update SDDPCM to a level higher than 2.1.2.3.

4. A customer is planning to purchase a fully populated Power 795. There are 65 applications which need to run and all need an AIX 7 environment. The architect is considering whether to use an LPAR for each application or to use a single large LPAR and have a WPAR for each application.
What must be considered before creating the environment?

A) Multiple IVE adapters are required to support all the partitions.
B) There is a limit of 32 Processors in a WPAR.
C) There is a limit of 64 WPARs in any AIX V7 global environment.
D) An activation key for LPARs with more than 128 processors is required.

5. 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) IVM-managed systems do not support inactive migrations.
B) IVM-managed systems reserve RAM allocations, even for inactive LPARs.
C) The target managed system already has the maximum number of partitions.
D) Active Memory Sharing (AMS) or Active Memory Expansion (AME) is required for RAM over commitment.
