  Hi,

+    /* The current Qemu infrastructure allows only for LUN 0 */
+    if (lun == 0&&  target<  MAX_RAID_DEVS)
+       cmd->lun =&s->luns[target];

One more thing which should be fixed in qemu instead of worked around in your driver. After all even good old parallel scsi knows multiple luns. Guess this is how you end up with 128 scsi devices (16 ids with 8 luns each)?

cheers,
  Gerd
