According to the Shark reference manual, a Target Reset has the effect of performing a LUN Reset on each LUN surfaced on the port. Interestingly, for FC (and not for parallel SCSI), Shark surfaces all LUNs on all ports (there are ACLs per LUN), so I assume a Target Reset has the unfortunate effect of reseting the entire Shark...
