AIX 6.1 Error - "A file, file system or message queue is no longer available."

Getting a strange error with a log file below. This is just a normal text log file that is written to by an application on the server. The applicaiton is down, however, I cannot read, remove or touch this file. The file shows on an ls listing but not an ls -al listing.

The file system is JFS2 on a SAN. AIX 6.1.

Any ideas how I can get rid of this file and its containing directory?

Thanks!

The solution to this problem was to unmount the file system and run a file system check. Appartently either the I-node or direcotory was corrupted.

Thanks,
