AIX高手挑战赛2009年赛总决赛试题必答题第二组.pptx

必答题第二组第二组第一轮1、在一个AIX生产系统中有一个文件系统/data（对应的LV是data_lv)），该文件系统位于内置SCSI磁盘上。为了提高可用性，需要将/data移到外接的SAN磁盘阵列上， SAN磁盘与SCSI磁盘属于不同的卷组。请问可以使用以下哪种方法？Use migratepv command to migrate the /data_lv from SCSI to SANUse mklvcopy command mirror /data_lv from SCSI to SAN Use mirrorvg command to mirror /data_lv from SCSI to SAN Use “cplv” command to copy data_lv from SCSI to SAN2、AIX中的multibos 功能允许在AIX基本操作系统（BOS）的rootvg中创建和维护两个bootable instances, 请问以下哪个文件系统是两个instances共享的？A. /B. /usrC. /optD. /tmp3、RSCT（Reliable Scalable Cluster Technology）包含一组软件元素，为AIX提供了丰富的集群环境支持。请问以下哪项不是RSCT的组成元素？Resource Monitoring and Control (RMC)Resource Monitoring and Control (ctrmc) subsystemRSCT core resource managers (ctcas)Topology Services subsystem (cthatsd).4、系统管理员想测试两台AIX服务器之间的网络带宽，以判断是否在网络上存在瓶颈。为此，需要产生很大的网络压力。请问最好采用以下哪一种方法进行测试? 采用rcp 命令, 再配合 netstat命令采用ftp命令, 再配合 dd 命令采用ftp命令, 再配合 cp 命令产生NFS, 再使用 cp 命令配合 netstat命令5、以下哪条命令可以显示当前系统active的内存使用情况?lsps –sbootinfo –rps auxiostat 5 5第二组第二轮6、From the HMC, where can you view the Partition Availability Priority value of a partition?A. From the partition’s propertiesB. From the HMC command line using lssyscfgC. From the Partition Availability Priority task in the GUID. Answers A and CE. Answers B and CF. Answers A and B7、Regarding Live Partition Mobility(LPM), which one of the following statements is TRUE?A. The destination system must have enough memory and processor resources unassigned before a migration can happen.B. You must create a new partition profile for the destination system.C. The destination system can accept physical I/O device assignments to be activated later.D. LPM is standard on all POWER6 technology-based servers.8、What must you do after changing the HEA’s MCS value so that it uses the new value?A. Power off the managed system and power it on againB. Reactivate all partitions which are using that HEAC. Shutdown all partitions first before changing the value, then reactivate themD. Do nothing. The MCS value can be dynamically modified.9、Which of
