You said: "And plugging any SE device onto an LVD bus causes the whole bus to fall back to SE. This includes terminators."
True, but if your terminator is LVD only, it will get hot!!! Not sure if it can be damaged, but it does get hot (or warm). :) I also believe some LVD devices do not support SE.

I think the SCSI vendors prefer to sell SCA drives rather than SCAM drives ;-) Drives with the SCA connector have power supplied to them and their SCSI ID configured automatically depending on which slot they're plugged into. If you're doing hotplug SCSI, it's probably with SCA drives. > Mixing devices with different electrical standards can be tricky. Some > can't be mixed. HVD is not compatible with any other. And plugging any SE devince onto an LVD bus causes the whole bus to fall back to SE. This includes terminators. -- "Next the statesmen will invent cheap lies, putting the blame upon the nation that is attacked, and every man will be glad of those conscience-soothing falsities, and will diligently study them, and refuse to examine any refutations of them; and thus he will by and by convince himself that the war is just, and will thank God for the better sleep he enjoys after this process of grotesque self-deception." -- Mark Twain - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
