[SunHELP] scsi warnings FC4700

On boot I'm getting scsi warnings for each LUN which is assigned to a
particular host. An example is below the only thing is see changing is the
requested block and LUN device path.  I can't get an answer from EMC on how
to diagnose this issue. From the Clarrion standpoint everything checks out
and there is no error in the event log that matches up with this warning.
Since the error is retryable I am assuming it completes what it needs to do
and moves on.  I haven't seen any issue with data integrity which should be
immediately obvious since an Oracle database resides on these LUN's.
Perhaps this is a timing issue, but I have seen these errors thrown when
initially setting up powerpath during the "powermt config" command.

Please advise on  what I should do to diagnose this issue.
