第1题：

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.

第6题：

在卷组datavg中有两个物理卷hdisk3和hdisk4。为了确定在该卷组中有哪些逻辑卷，正确的命令是（）。

• A、lslv-l datavg
• B、lsvg-l datavg
• C、lsvg-p datavg
• D、lsvg datavg

第7题：

The 'lsvg -o' command is run with an output of only rootvg, but the server has another volume group named datavg, which is notdisplayed. What is the likely cause?（）

• A、datavg is in an offline state.
• B、'lsvg -o' only displays the root volume group.
• C、'lsvg -o' only displays the fist volume group.
• D、datavg has no filesystems and therefore, is inactive.

• A、lslv rootvg
• B、lsvgs rootvg
• C、lsvg rootvg
• D、lspv hdisk0

第10题：

A SAN needs to undergo disruptive maintenance, which will effect a hosted production system with multiple applications and related volume groups, one of which, datavg, resides on the SAN. There is one spare disk in the system but it is smaller than datavg. How can application outages and risk of corruption be minimized?（）

• A、Stop the applications in all data volume groups and shut the system down during the outage period.
• B、Stop the applications in datavg, unmount all datavg filesystems, varyoff datavg, and export datavg.
• C、Stop the applications in datavg, unmount all datavg filesystems, and reduce datavg by the SAN disks.
• D、Use the 'cpvg' command with the -z option to copy and compress datavg to different physical volumes.
