Ed,
>>Unless really old (SCSI-1 CCS or earlier) drives are in use, the channel should negoatiate with each device as necessary; in some cases, you might have to force the HA to negotiate with a given device at a lower speed, but not all devices.
Thanks for the clarification -- I knew somebody here (I suspected you) would immediately know what I was only hinting to Jim about. I saw your very detailed post to him right after sending mine <g>.
