The only downside on that is, that I will have a long line for the weightedpath regex definition as this has to be for each VPLEX-port.
At least I will have reduced the need to write something on my own ;)
Best regards,

Hehe. No alua for you (TPGS=0).
But that's EMC for you; probably you should count yourself lucky

Why don't you use the 'by-path' symlinks for the device name in
weightedpath?
They'll include the target port WWN, so should give you what you want.
