Doesn't the box give usable serials on SCSI INQ ?
The multipath tool already fetches that (you can see the values when debug is enabled), and proposes to group by these strings.
I guess it could be useful to fetch the target node_name anyway.
Might work too.I assume that once I done this all I need to do is write my own priority finding program that looks these up and groups them into a priority depending on the target node_name /
So you owe me an entry in the TestedEnvironments page in the Wiki :)Thanks for the work on this, we were able to add a second lun, add it to our lvm group and then grow the filesystem on top of it without any downtime!
