Thank you very much to all who have answered!
The original question was:
Here, we had the discussion how to get the host-id of a KGPSA
seen by the storage area network (SAN).
Well, one way is to use the Firmware of the HSG80 controller and
issue "show connections".
Then, we will get the HOST_ID's of the connected hosts.
But, how, can we read in the HOST-ID directly from TRU64
without using this indirect approach?
Answer:
-------
There are two WWIDs which can be seen
directly via HSG80:
a HOST_ID and an ADAPTER_ID
The later can be found in /var/log/messages
the former can be requested on TRU64 V5.1B by
> hwmgr -show fibre -adapter
which gives a WWPN (i.e. the Adapter_ID or port id)
and a WWNN (i.e., the HOST_ID)
The node WWID (HOST_ID) would apply to both ports,
or you can address each port individually.
This is useful when zoning for redundant paths on different
fabrics.
Thanks to Alan Davis for his explanations.
