单项选择题The first step documented in Company.com’s HACMP test plan is to start the cluster manager on the normal service node and verify that HACMP daemons have started with the ’lssrc -g cluster  command.  What daemons MUST show as active in the ’lssrc -g cluster  command to have an operational cluster？（）

A. clstrmgrES，clsmuxpdES
B. topsvcsd，grpsvcsd，exaixos
C. topsvcsd，grpsvcsd，clinfoES，grglsmd
D. clstrmgrES，clsmuxpdES，topsvcsd，grpsvcsd

单项选择题A node in a three-node cluster was started， ad it acquired the following three cascading resourcegroups：  ’rg1’， ’rg12’， and ’rg3’. The cluster design is to have ’rg1’ normally Node ’A’， ’rg2’ normally on Node ’B’， and rg3’ normally on Node ’C’.  How can the administrator reposition the resource groups and correct the problem？（）

A. Change the cluster resource group definitions from cascading to rotating，synchronize the cluster，and restart HACMP
B. Edit the /urs/es/sbin/utilities/clhosts file to reflect he desired node-to-resource group relationships and restart HACMP
C. Use the clRGMove utility move rg2 o Node ’B’ and rg3 to Node ’C’，then start the cluster manager on Nodes ’B’ and ’C’ with the clstart utility
D. Disable Inactive Node Takeover，check the node priority list in the resource groups definitions，synchronize the cluster，and start HACMP on Nodes ’B’ and ’C’

单项选择题Following a successful migration，it is highly recommended that concurrent Volume Groups be Converted to enhanced concurrent capable Volume Groups.  In order to follow this recommendation，what step must be completed first？（）

A. The Volume Groups must be changed with chvg -E vgname.
B. The Volume Groups must be a member of a resource group and must be varied on al nodes of       the cluster.
C. The Volume Groups must be a member of a resource group and must be varied off all nodes      of the cluster.
D. The Volume Grups cannot be changed to enhanced concurrent capable because they must be      recreated with mkvg -C vgname.

单项选择题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.
D. The MISSING_PV=TRUE environment variable has been set causing the volume group to be forced online.
