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

1. A VIO server administrator is configuring MPIO-based storage for a new LPAR named P7_3_AIX.The administrator runs the lspv -free command and sees 4 disks free. The lsmap -all command confirms that the disks are free. A check of the list of LPARs shows the following: In order to avoid problems, what else should be verified before mapping storage to the new LPAR?

A) If the free disks are allocated to P7_3_AIX
B) If the free disks are allocated to P7_2_AIX
C) That the free disks are allocated to a shared storage pool
D) That the free disks are MPIO capable

2. 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?

A) Use DLPAR to increase the Maximum virtual adapters to 50.
Use DLPAR to create the vSCSI adapters on slots 40/41 and map them as "Any client
partition can connect".
B) Change the Maximum virtual adapters to 50 in the VIOS partition profile.
Create the vSCSI adapters on slots 40/41 in the VIOS partition profile and map them as
"Any client partition can connect".
Reboot the VIOS.
C) Change the Maximum virtual adapters to 50 in the VIOS partition profile.
Create the vSCSI adapters on slots 40/41 in the VIOS partition profile and map them to the
new client.
Shutdown and reactivate the VIOS.
D) Use DLPAR to increase the Maximum virtual adapters to 50.
Use DLPAR to create the vSCSI adapters on slots 40/41 and map them to the new client.

3. A user has accidentally deleted critical system files on an LPAR. Storage on the LPAR is provided using both vSCSI and NPIV. The administrator is preparing to reinstall the LPAR, but has concerns about the existing NPIV configuration. Which statement concerning WWPNs is correct?

A) Assigned WWPNs are regenerated during a reinstall for boot devices, but preserved for secondary storage.
B) During the reinstall of AIX, the HMC will assign new WWPNs to the adapters.
C) The virtual_fc_adapters LPAR attribute must be verified prior to the reinstall and suitably updated to preserve all existing WWPNs.
D) Providing the configuration of the virtual Fibre Channel adapters remains unchanged in the LPAR profile, the existing WWPNs are preserved.

4. A client is designing a system to support three 24x7 applications, each in a different environment. The plan is to host these applications on a new POWER7 based server to add to their existing POWER6 servers. Virtual I/O Server will not be used.
The applications have the following OS and processor requirements: AIX 6.1 with a peak of 2 cores between 10am-2pm
AIX 5.3 with a peak of 2 cores between 5pm-10pm
AIX 5.2 with a peak of 2 cores between 3am-7am
Outside the peak periods, the processor utilization is extremely low.
Which of the following configurations supports the design requirements?

A) The LPAR profiles can set the processor mode to POWER6
The AIX 6.1 and AIX 5.3 LPARs can be migrated using Live Partition Mobility.
The AIX 5.2 could only be migrated if it is in a WPAR.
B) A minimum of four processor activations is required.
Two dedicated processors for an AIX 5.2 LPAR.
AIX 5.3 and AIX 6.1 can share 2 processors
C) Each applications each needs its own LPAR running native AIX.
The LPAR must be running the appropriate version of AIX.
The LPARs can all use the shared pool and be uncapped.
D) The AIX 5.2 can be hosted in a WPAR in an AIX 7.1 LPAR.
The AIX 5.3 and AIX 6.1 can each have their own LPAR.
All LPARs can use the shared processor pool.

5. A second virtual disk has been added to a SuSE Linux LPAR on the existing vhost0 adapter. What must be done for this disk to be recognized on the Linux LPAR?

A) /usr/bin/rescan-scsi-bus
B) /bin/kpartx -a -v /dev/sdb
C) echo "- - -" > /sys/class/scsi_host/host0/scan
D) /usr/bin/cfgmgr
