Unfortunately, DragonFly (and most of the other *BSDs I think) doesn't have a good answer for persistent binding. You can setup the kernel to "wire down" a particular bus/target/lun to a specific device, but I don't think this would work for SANs.

More on the same topic!

Here's an excerpt from the linux fstab(5) manpage:

--- snip ---

Instead of giving the device explicitly, one may indicate the (ext2 or
xfs) filesystem that is to be mounted by its UUID or volume label (cf.
e2label(8) or xfs_admin(8)), writing LABEL=<label> or UUID=<uuid>,
e.g., `LABEL=Boot' or `UUID=3e6be9de-8139-11d1-9106-a43f08d823a6'.
This will make the system more robust: adding or removing a SCSI disk
changes the disk device name but not the filesystem volume label.

--- snip ---

Wonder if something like this would make sense for DragonFly?
