IBM Assessment: Power Systems Virtualization Technical Support for AIX and Linux -v2 Sample Questions:
1. An administrator is preparing to upgrade the environment's dual Virtual I/O servers (VIOS) from V1.2 to V2.1
What must considered in preparation for this upgrade?
A) VIOS V2.1 requires AIX clients to be running AIX V6.1 at a minimum.
B) All client LPARs must be shutdown as both VIO servers have to be upgraded to V2.1 at the same time.
C) The only upgrade method that will be supported is using NIM because the current VIOS is lower than V1.3.
D) The VIOS must be upgraded to the latest fixpack of V1.5 before upgrading to V2.1.
2. An administrator has the following configuration on a VIO Server:
Why is this error being displayed?
A) ent3 has no interface connected
B) ent3 is a LHEA port and requires the -L flag
C) ent3 is controlled by the SEA
D) ent3 is configured as 'standard' instead of '802.3ad'
3. 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?
A) The NPIV adapters on the VIOS LPARs were not tagged as being "required for partition activation."
B) The WWNs will have changed due to the recycle of the Hypervisor. The chsyscfg -r command should be used to recover the previously allocated WWN.
C) The virtual Fibre Channel client adapters were dynamically allocated to the LPARs before being added to the partition profile.
D) The option to randomly assign WWNs for security reasons has been selected.
4. A customer is in the process of configuring a redundant pair of VIO Servers. They need to test that SEA failover has been correctly enabled. Which command can the padmin UserID use (on the active SEA, ent4) to manually force an SEA failover event?
A) chdev ent4 -attr ha_mode=True
B) chdev -l ent4 -attr ha_mode=failed
C) chdev -dev ent4 -attr ha_mode=standby
D) chdev -d ent4 -attr ha_mode=Active
5. An administrator has defined a new virtual SCSI server device, vhost0, to support a client LPAR on a new system. A disk, hdisk2, has been presented from a SAN to the VIO server. The administrator attempts to map the disk on the VIO server using the following command. mkvdev -vadapter vhost0 -dev hdisk2 -vdev client_rootvgThe error 'client_rootvg" is not a valid backing device' was received. Which of the following explains the error?
A) The -dev and -vdev flags have the incorrect parameters.
B) The virtual target device "client_rootvg" is already in use.
C) The disk is already allocated to another VIO server
D) The disk is formatted at 522 bytes/block.
