Hello Hannes,
sorry for top-posting, but crappy Notes is not really a good client
for mailing-list - at least I don't know how to avoid such mess.

Hehe. No alua for you (TPGS=0).
But that's EMC for you; probably you should count yourself lucky
that it's not claiming compability to SCSI-2 ...
and well, 'weightedpath' is also available in RHEL, but only queries
for the device name and the SCSI-address. I wanted to query the
remote-port of the storage-device - which is the frontend wwn of the
storage device.
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.
Cheers,
Hannes
