Many thanks to everyone for your speedy reply,

The general concensus is that this kind of errors probably signify that some block has gone bad inside
the disk. Some managers have suggested to use the "format" command with either the "defect" subcommand to count
the defects or the "analyze" subcommand to possibly make repairs. However to use "analyze" the disk must be 
unmounted. Since this is a disk that is a submirror, detaching it and reattaching it to SVM may prove more work 
than its worth it. 

Most of the replies say that if the problem reappears several times, it will be a good time to change the disk. But
if this is a single occurence, it can be ignored, at least temporarily. 

Kind regards,
Athanasios
