Hello Tim, As far as I know the Linux SCSI stack does not yet support any SCSI devices for which a single SCSI command affects multiple (two in this case) LUNs. Adding such support may take significant work. There will also be the disadvantage that most SCSI core contributors do not have access to a multi- actuator device and hence that their changes may break support for multi- actuator devices. PS: the preferred style for all Linux kernel mailing lists I know of is to reply below a previous message. See also https://en.wikipedia.org/wiki/Posting_style. Thanks, Bart.
