A hardware RAID?  What type of controller?  What type of SCSI controller?

These look like generic SCSI errors.  How sure are you of the hardware --
the RAID itself, the SCSI controller, etc?  Have you done the usual --
checked cables, termination, termination (yes, again ;), that you used the

This is XFS' standard response when it detects disk errors, in order to
prevent (further) corruption.
