6027-688   Failed to read file system descriptor.

Explanation

The disk block containing critical information about the file system could not be read from disk.

User response

This is usually an error in the path to the disks. If there are associated messages indicating an I/O error such as ENODEV or EIO, correct that error and retry the operation. If there are no associated I/O errors, then run the mmfsck command with the file system unmounted.
