Udev to the rescue, see /dev/disk/by-path! (Because that is what hdx reflected in a way.)

User-friendly disk names Posted Jun 23, 2011 23:43 UTC (Thu) by giraffedata (subscriber, #1954) [Link] But we're talking about kernel device names, not names of device special files. When the kernel warns about errors on a disk device, it identifies it by kernel device name and udev is irrelevant. Except with at least some of these proposals, where udev could give the kernel a more meaningful name to use in communicating with the user. The "sdaq" naming is really just a waste of a namespace. The kernel might as well talk to you in major/minor numbers.

But udev helps you to map sdX to real hardware:
# ls -lR /dev/disk/by-* | grep sdc1
I'm sure there is some "udevadm info" invocation which will do the same and even provice more info.

Yeah, but only if you *get* a /dev/sdx name. I'm playing with Open-iSCSI for the first time, on Suse, under Xen, and I can only get it to do that for the first two mounts; after /dev/sdb, I don't get a device anymore. I assume there's some knob I haven't found yet, but the doco on Open-I is kinda thin on the ground...
This planning treads much the same ground as the best writeup I found on the topic:
http://www.idevelopment.info/data/Unix/Linux/LINUX_Connec...
and indeed, that gent's userspace approach may well belie the arguments of those who say this needs to be kernel-side, all by itself.
