After an HACMP migration， which included a large number of shared disks，cluster testing is   performed. During testing， it becomes apparent that Fast Disk Takeover is not working properly.  Which of the following is the most likely cause of the problem？（）  

• A、 The shared volume groups have not been converted to Big VGs.
• B、 The ’t factor" needs to be set on the volume group using chvg -t 2 vgname.
• C、 The shared volume groups have not been converted to enhanced concurrent mode.
• D、 The shared volume groups need to be varied on using the passive varyon option on all nodes.

第5题：

An  administrator  has  a  server  experiencing  performance  problems  with  logical  volumes  within  a particular volume group.  Which command can report I/O statistics for logical partitions with each logicalvolume within the volume group（）

• A、Islv
• B、vmstat
• C、iostat
• D、Ivmstat

第6题：

While adding the forced varyon volume group option， it is decided to create a disk heartbeat  Network over the disk paths. Which HACMP function is used to create disk heartbeat devices？（）

• A、 The Disk hearbeat facility is initialized when creating enhanced concurrent mode volume groups through HACMP.
• B、 HACMP does not create the disk heartbeat area directly； RSCT facility creates the area used for the disk heartbeat when the device is started by Group Services.
• C、 The ’Chdev -v-C " command creates an enhanced Volume Group from an ordinarilyVolume Group. This creates the heartbeat region on the vfirst disk in the chain.
• D、 The disk heartbeat area on the disk is created and initialized when the device is created inHACMP "Extended Configuration -> Extended Topology -> Disk heartbeat facility" smit path.

第7题：

Using the C-SPOC utilities， an administrator has created a new volume group and filesytems. Theadministrator performs an Isvg -I command on the volume group and notices that the log logical volume created in C-SPOC is closed/syncd and loglv01 has been created and is in use.  What step was required in order for the logfile created by C-SPOC to be used.（）  

• A、 Perform the C-SPOC logform utility option prior to creating any filesystems.
• B、 Manually perform a logform outside of C-SPOC prior to creating any filesystems.
• C、 Run a logredo command and select log logical volume created in C-SPOC as the preferred jfslog.
• D、 Use C-SPOC to delete and recreate the log logical volume，set the perform logform option to true.

A cluster administrator is concerned about using the forced varyon resource group function. Although the function provides increased data availability if it is enabled for a cluster resource group， management is concerned about data integrity.  If a varyonvg command fails， an HACMP forced varyon will only occur if which of the following is true？（）  

• A、 A loss of quorum has occurred on one of the disks in the failed volume group.
• B、 Selective fallover caused by an application moves a resource group to a takeover node.
• C、 A check is made to ensure at least one complete copy of all data is available in the volume group.
