In clause 4.2.1 it states that world wide names are unique for devices
AND ports within the transport protocol. I interpret this to mean a =
disk
with two ports will have three WWNs. One for the device and one for =
each
of its ports.
In clause 4.6.2 third paragraph it states that in an expander there can
be an expander device and within it three ports all sharing the same
WWN.
Is my interpretation correct?
If so, isn't 4.6.2 a contradiction of 4.2.1?
Thanks.
