Again with the tapes

In a previous post I said that to get around devices changing their numbering, it was useful to use the /dev/tape/by-id instead of the generic /dev/nst0. Unfortunately, this is also imperfect I've just learned as the device which was previously "scsi-35000e11138aa0001-nst" this time came up as "scsi-35000e11138aa0001". And you can guess how gracefully the software handled that (not at all). Now I don't know if was a driver update (possible) or if the device was switched to a different SAS interface (also possible), or maybe just the gremlins. Whatever it was, once again, I had to reconfigure the software to find the new device ID.
