Zoning

 Grouping of Host HBA WWPN and Storage Front End Ports WWPN to speak each other.

Cisco Zoning Procedure


All the commands should be run in Configuration Mode.

Switch Name # config t   (Configuration terminal)

Switch Name (config) # zone name ABC vsan 2

Switch Name (config – zone) # member pwwn 50:06:01:60:08:60:37:fb

Switch Name (config – zone) # member pwwn 20:00:00:24:ff:0d:fc:fb

Switch Name (config – zone) # exist

Switch Name (config) # zoneset name XYZ vsan 2

Switch Name (config – zoneset) # member ABC

Switch Name (config – zoneset) # exist 

Switch Name (config) # zoneset activate name XYZ vsan 2

General process to implement zoning activity

The Platform team will inform you that they are going to provision a new server in the environment and requests you to give the free port details on the switches which are exists in the data center.

Once you share the information to Platform team, they co-ordinate with the Data center guys to lay the cables between the server and switch. (Already the storage ports or tape library are connected to the switch).

After laying the cables, Platform team will requests you to check the connectivity and they shares the server HBA WWPN to verify with the connected one.


Zoning-with-single-path
Physical Cabling between Server,Switch and Storage with Single path



Zoning-with-double-path
Physical Cabling between Server,Switch and Storage with Multipath

To check the fabric login details, by using the command

 Switch # sh flogi database 

The connected server HBA WWPN are listed below, once confirm we have to proceed with the zoning activity, if not check the cable connectivity between the server and switch.

Some useful commands for your reference

To enable the port status

Switch # config t

Switch (config) # interface 1/5

Switch (Config-Int) # no shutdown


To disable the port status

Switch # config t

Switch (config) # interface 1/5

Switch (Config - Int) # shutdown


To see the specific port details

Switch # show interface fc1/1
