it's usual for the SCSI HBA to assign a targetID for itself. besides having to use a different number, is there any real reason you want to change them? perhaps a better solution would be to patch scsictl such that we can detach via autoconf name as well as scsi addresses. maybe we should do this anyway.. .mrg.
