During phase 1, fsck(1M) found more than 10 bad (out-of-range) blocks associated with the specified inode number.
With this many bad blocks, it might be preferable to restore the filesystem from backup tapes.
For more information on bad blocks, see the section on checking filesystem integrity in the System Administration Guide, Volume I. If you are using the AnswerBook, "bad blocks" is a good search string.
