What has been less than optimal is naming the disks.
I have an ATTO ExpressSAS H1288 HBA, and Areca ARC-4038 expander, they a connected via a 100 meter 4x12g optical cable.
As it stands I have imported things via the SAS ID

The issue with this, as the last @nn is the SAS disk number and it's assigned in order of detection. It's also a hex number.
I would like to map this to physical slots on the expander using the vdev_id.conf file. I'm able to identify disk to phy port mapping using the atto utilities.
For example PCI0@0-PEG1@1,1-PEGP@0-@18:0, target: 0x18 / 24

(I've only show the relivent output for this target)

This gives the expander PHY of 26d which is port C1-3 on the expander and connected to Slot 3 on my enclosure.
I'd like to have this named 'Slot-U3' in the vdev_id.conf file so if the disks move around, they are always going to be listed in the slot they are in. This makes it much easier to find failed disks without a detailed lookup too.
I've looked at the vdev_id.conf.sas_direct.example, but am unable to find the format it wants to get this to work.
Does anyone have a working example of this, or know if this even works on OSX?
