• B、Run mkvdev on the VIO server to re-create the devices and re-mirror rootvg.
• C、Run varyonvg rootvg to refresh the volume group.
• D、Run syncvg on the rootvg to synchronize rootvg.

第3题：

第5题：

Error log analysis indicates that a disk is starting to fail and will need to be replaced. The failing disk contains multiple logical volumes which span multiple disks. A free disk has been added to the failing disk’s volume group.Which of the following is the most efficient method to move the data from the failing disk to the new disk？（）

• A、Back up the data， remove the failing disk from the volume group， then restore the data to the new disk.
• B、Use the migratepv command to move data from one disk to another and then remove the failing disk from the volume group.
• C、Use the mirrorvg command to mirror the data to the new disk， break the mirror and then remove the failing disk from the volume group.
• D、Create a new filesystem on the new disk and use the mv command to move the data to the new filesystem， and then remove the failing disk from the volume group.

第6题：
