Some of the sg_ses and sg_vpd tools from the sg3_utils package can sort of give
that information if you have an SES compatible backplane/expander.
It stops working when disks die though; so you would want to record any
mappings somewhere for later reference. (Or just look for the blank spot in
the map later on...)
I have been working on some scripts; but they are still in a very 'ugly' state.
sg_vpd will give you a 'sas address' for any disk. sg_ses --page=0xa
/dev/es/ses??? will list SAS addresses for each slot; along with some other
stuff.
Match those up and you have a map of slots / disks.
I dump the output from the following script for each 'active' disk into a file
to make a map.
I've been working on a script to blink LED's as well; but it involves sending
binary blobs to sg_ses; and I'm not entirely sure it wouldn't brick another
brand of expander...
