A system administrator has been asked to migrate the dev_vg volume group from server A to server B. The dev_vg volume group contains a single filesystem named "/development". To prepare for migration， which of the following is the correct sequence of commands for removing the volume group from server A？（）

• A、exportvg dev_vg； umount /development； varyoffvg dev_vg
• B、varyoffvg dev_vg； umount /development； exportvg dev_vg
• C、umount /development； exportvg dev_vg； varyoffvg dev_vg

第5题：

An administrator is attempting to recover a filesystem that fails to manually unmount. The fsck command produces the following output： The current volume is： /dev/fslv02 File system is currently mounted.   Invalid file system size in the primary superblock. Invalid file system size in the secondary superblock.  Primary superblock is corrupt. Secondary superblock is corrupt.   fsck： 0507-018 Superblock is corrupt and cannot be repaired. Both primary and secondary copies are corrupt.Cannot continue tried to mount  Which steps will resolve the problem？（）

• A、Reboot the server into maintenance mode and run ‘fsck’ with the ‘-p’ parameter while the filesystem is mounted.
• B、Reboot the server into maintenance mode and run ‘fsck’ with the ‘-y’ parameter while the filesystem is unmounted.
• C、Force a umount of the filesystem with ‘umount -F /dev/fslv02’， and then run ‘fsck -p /dev/fslv02’ while the filesystem is unmounted.
• D、Force a umount of the filesystem by varying off the hosting volume group and then varyon the volume group. This will permit ‘fsck -y’ to be run against the failing filesystem.

第6题：

A system 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 logical volume within the volume group？（）

第7题：

An AIX server will not boot in normal mode and the server must be booted into maintenance  mode to rebuild the boot logical volume. A NIM master is not defined in this environment.  How is the system booted into maintenance mode to perform this task （）

• B、Boot media such as CDROM or Tape is required to boot into maintenance mode. When inserted into the proper device the system automatically boots into maintenance mode when it can not boot into normal mode.
• C、Apply power and the server automatically boots into maintenance mode where you can select your disk to rebuild the boot logical volume.
• D、Boot media such as CDROM or Tape is required and an administrator must select the proper SMS menus to get into maintenance mode.
