IBM SAN Switch Question
Hi all,
My vendor did not create any zone for my SAN switch and all servers are already in production.
Now, i want going to create two zones and assign members to it, will i lost the data?
Is there any procedure i should follows?
Thanks

Excuse me...that should have been "zones have *no* effect on the data on the disks."

Thank guys,
I know for hard zoning, we go by the port number but for soft zoning, do you guys use the WWNN or WWPN ? what the difference anyway?

The WWNN (World Wide Node Name) is the address that is phsically "burnt" on to the FC device (HBA for example) so it is analagous to a MAC address. The WWPN (WW Port Name) is assigned by the fabric (the FC switch) when the device logs in to the fabric (FLOGI - Fibre LOG In). The WWPN usually only differs by one bit. For example, WWNN of QLogic FC HBA's is 20:00... WWPN is usually 21:00.... The full WWN is WWNN:WWPN - a full 128 bit disaster! To top that all off, once the server (or storage) has logged into the switch (and the end to end log-in a PLOGI) it is allocated a 24 bit ID that is used for FC conversations instead of the WWN.
In setting up soft zoning, I usually select the WWNN for the servers and the WWPN for the storage (I work with EMC kit a lot and the WWN's for the FC attached storage ports are WWPNs).
In essence, you can use either WWPN or WWNN, but check with IBM as they may have their own zoning requirements.
