D.The LED C31 means that there is a corrupted /dev/hd5. Boot into maintenance mode, fsck /dev/hd5 and then issue the bosboot command.

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: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 whilethe filesystem is unmounted

C.Force a umount of the filesystem with ‘umount -F /dev/fslv02‘, and then run ‘fsck p /dev/fslv02‘ whilethe file system is unmounted
