That's a definite weakness of the old scheme and part of the reason it was changed for 2.5. In the meantime, you can try doing this. After you've switched the drives, do "echo scsi remove-single-device 0 1 2 3 >/proc/scsi/scsi" with "0 1 2 3" replaced by your "Host Channel Id Lun". Then do "echo scsi add-single-device 0 1 2 3 >/proc/scsi/scsi" again with "0 1 2 3" replaced by your "Host Channel Id Lun". Thsse commands are a beta feature, so they might not work perfectly. But it's certainly worth a try.
