单选题 Company.com is migrating from a third party managed disk subsystem to an IBM TotalStorage Enterprise Storage Server. Connection of the new storage server is complete, and it has been tested on all of the nodes in the three node HACMP cluster.  How does the customer migrate to the new storage server with minimum down time?()

A

 Shut down one node at a time and let the other node serve the application

B

 Stop HACMP with the forced option and perform migration of the disks on one node,then restart HACMP

C

 Stop both nodes and perform the migration all at once using standard AIX commands in parallel, then restart the cluster

D

 Use C-SPOC to add the new disks to the cluster and migrate the information off the existing disks, then remove the old disks with C-SPOC

单选题 When a problem occurs in an HACMP cluster,which log file will show the high level overview of the cluster operation?()  

A

 /tmp/hacmp.out

B

 /tmp/clstrmgr.debug

C

 /usr/es/adm/cluster.log

D

 /var/hacrmp/clverify/clverify.log

单选题 Which log contains the output generated when starting and stopping a cluster?()

A

 tmp/cspoc.log

B

 /tmp/hacmp.out

C

 /var/adm/ras/hacmp.error

D

 /var/hacmp/clcomd/clcomddiag.log

单选题 Company.com has two sites that are 3072 kilometers apart and wants to implement HACMP  between eh two locations. The nodes at each location must be capable of running the application in the event of a failure. Currently the customer’s disk technology is SCSI.  How can HACMP be used in this environment?()  

A

 HACMP cannot span sites; the environment must be contained in a single site.

B

 HACMP/XD://HAGeo has unlimited distance mirroring that may be appropriate for this environment.

C

 HACMP cannot be split into two sites that exceed the limitation s of the storage cable length.

D

 HACMP/XD://PPRC that is included with the base HACMP distribution will enable site-to-site  communications in HACMP.

单选题 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.

单选题 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.

单选题 Company.com has decided to implement VPN for all network traffic. How might this might affect HACMP?()  

A

 Only the heartbeat IP network can exist in a VPN style network.

B

 HACMp must have separate VPN’s for all ’non-service’ and ’service’ adapter networks.

C

 If a VPN is used for IP traffic the heartbeating must be done over disk connections.

D

 HACMP can exist in a VPN network environment,but special considerations must be addressed.
