An administrator has just imported a shred Volume Group that had been created on another  system in the cluster. In order for the shred volume to be used in the cluster， what is the most important step for the administrator to take first？（）   

• A、 Change the quorum required to false.
• B、 Change the Volume Group auto vary on to yes， and then vary off the Volume Group.
• C、 Change the auto vary on value of the Volume Group to no， and then vary off the volume group.
• D、 Set the Volume Group major number to the same value that the Volume Group had on the system on which it was created.

The Cluster Administrator wants to use disk heartbeats as a non-IP network. What Volume Group consideration must be accounted for prior to configuring disk heartbeats？（）  

• A、 The Volume Group major number must be the same on all nodes.
• B、 The Shared Volume Group must be created with the Big VG format.
• C、 The Volume Group must be created as Enhanced Concurrent Capable.
• D、 The "t factor" must be doubled to create the reserved area for disk hearbeats.

The system administrator notices that there is an I/O bottleneck on one of three disks in datavg volume group. This problem disk contains the JFS log， loglv00 and one filesystem， /mydatabase.  There are no other logical volumes on this disk.  Which of the following options would be the best solution？（）

• A、 Increase the size of the JFS log logical volume so more transacations can be written to this log.
• B、 Create a second， additional JFS log and have the /mydatabase logical volume point to both JFS logs.
• C、 Migrate the JFS log device to another physical disk in the same volume group.
• D、 Only one JFS log device for each volume group can be used.  Use the migratepv command to move the JFS log device to an empty disk in another volume group.

An administrator is trying to extend an existing volume group with a new hard disk, but the extendvg command returns the following error. 0516-1162 /usr/sbin/extendvg. Warning, The Physical Partition Size of 64 requires the creation of 8924 partitions for hdisk11. The limitation for volume group datavg is 1016 physical partitions per physical volume. Use chvg command with -t option to attempt to change the maximum Physical Partitions per Physical volume for this volume group. The chvg -t may or may not allow the extendvg command to succeed. What is the implication of using this option?（）

• A、It reduces the maximum file size allowed within the given volume group.
• B、It reduces the maximum number of files allowed within the given volume group.
• C、It reduces the maximum number of logical volumes allowed within the given volume group.
• D、It reduces the maximum number of physical volumes allowed within the given volume group.

• A、There is not an available disk to allocate to the snapshot volume group
• B、One of the physical volumes associated with rootvg has a status of "missing"
• C、Rootvg is running in enhanced concurrent mode
• D、A snapshot volume group cannot be created for the rootvg
