I am seeing a bunch of these errors in my messages file

The device 8a.29 is a 72G FC hard drive in a DS-14 Shelf(not MK2), it is not the only device that is seeing this error, a few other hard drives are also reporting this error. All the drives reporting the error are in the same shelf. I have 2 shelves on this filer and they are connected to one dual channel FC card in a redundant loop fashion.
If you look at 8a.17, it has about 1200 Loss of sync count on it. I am not sure why the filer has not started using "8b.17" instead(and that I will know that this might be a cable problem or port on card problem) If the problems continue with 8b.17, that would be indicative of a problem with the hard drive electrical contacts or the shelf.
Any thoughts ?

We had similar behavior on a FAS960 and it turned out to be a bad FCAL controller.
It looks like most your errors are on the 8a loop, so I would get the FCAL card in slot 8 replaced.
