Introduction
This document describes the PWWN (Port Worldwide Name) zoning and device-alias zoning with SAN (Storage Area Networking) processes.
Prerequisites
Requirements
Cisco recommends that you have knowledge of this topic:
- How to add zones in an network environment.
Components Used
This document is not restricted to specific software and hardware versions.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.
PWWN Zoning
Prerequisites
Before you add a new zone you need to determine this information:
- What devices can you zone together?
- What VSAN does the new zone belong to?
- Is there an active zoneset? If so, what is the name of the zoneset?
Once the VSAN number has been established, you can check for an active zoneset with this command:
switch#show zoneset active vsan X
Where X is the vsannumber provided.
Example:
Adding zones for Host_A to talk to Target_1 and Target_2 to the active zoneset Zoneset_10 in vsan 10.
| End Device |
PWWN |
| Host_A |
21:01:00:e0:8b:39:a9:07 |
| Target_1 |
21:00:00:20:37:af:a5:93 |
| Target_2 |
21:00:00:20:37:af:a5:3d |
Add Zones
switch# conf t
switch(config)# zoneset name Zoneset_10 vsan 10
switch(config-zoneset)# zone name Host_A-Target_1
switch(config-zoneset-zone)# member pwwn 21:01:00:e0:8b:39:a9:07 switch(config-zoneset-zone)# member pwwn 21:00:00:20:37:af:a5:93 switch(config-zoneset-zone)#
zone name Host_A-Target_2 switch(config-zoneset-zone)# member pwwn 21:01:00:e0:8b:39:a9:07 switch(config-zoneset-zone)# member pwwn 21:00:00:20:37:af:a5:3d
switch(config-zoneset-zone)# zone commit vsan 10 switch(config)# zoneset activate name Zoneset_10 vsan 10 switch(config)# zone commit vsan 10
Command Explanation:
| Command |
Explanation |
| switch#conf t |
Enters configuration terminal |
| switch(config)# zoneset name Zoneset_10 vsan 10 |
Enters Zoneset configuration mode. Creates Zoneset_10 for vsan 10 if it does not exist |
| switch(config-zoneset)# zone name Host_A-Target_1 |
Enters in-line Zone configuration mode. Creates zone Host_A-Target_1 in vsan 10 and as a member to Zoneset_10 if it does not exist |
switch(config-zoneset-zone)# member pwwn 21:01:00:e0:8b:39:a9:07 |
Add pwwn as a member of zone Host_A-Target_1 |
switch(config-zoneset-zone)# member pwwn 21:00:00:20:37:af:a5:93 |
Add pwwn as a member of zone Host_A-Target_1 |
| switch(config-zoneset-zone)# zone commit vsan 10 |
Commits the changes made to the zones and zoneset in vsan 10. Used only if enhanced zoning is enabled |
| switch(config)# zoneset activate name Zoneset_10 vsan 10 |
Sets the active zoneset as the currently configured Zoneset_10 in vsan 10. Note that only 1 zoneset can be active in a vsan at a time |
| switch(config)# zone commit vsan 10 |
Commits the change made to the zoneset in vsan 10. This step is required in enhanced zoning mode after an activation in order for the new activation to occur |
Device Alias Zoning
Prerequisites
Before you add a new zone you need to determine this information:
- What devices can you zone together?
- What VSAN does the new zone belong to?
- Is there an active zoneset? If so, what is the name of the zoneset?
- Map Device Alias/PWWN.
Once the VSAN number has been established you can check for an active zoneset with this command:
switch#show zoneset active vsan X
Where X is the vsannumber provided.
Example:
Adding zones for Host_A to talk to Target_1 and Target_2 to the active zoneset Zoneset_10 in vsan 10.
| End Device |

Configure Device-Alias
switch# conf t
switch(config)
switch(config)# device-alias database
switch(config-device-alias-db)# device-alias name HOST pwwn 21:01:00:e0:8b:39:a9:07
switch(config-device-alias-db)# device-alias name TARGET1 pwwn 21:00:00:20:37:af:a5:93
switch(config-device-alias-db)# device-alias name TARGET2 pwwn 21:00:00:20:37:af:a5:3d
switch(config-device-alias-db)#exit
switch(config)#device-alias commit
Add Zones
switch# conf t
switch(config)# zoneset name Zoneset_10 vsan 10
switch(config-zoneset)# zone name Host_A-Target_1
switch(config-zoneset-zone)# member device-alias HOST
switch(config-zoneset-zone)# member device-alias TARGET1
switch(config-zoneset-zone)# zone name Host_A-Target_2
switch(config-zoneset-zone)# member device-alias HOST
switch(config-zoneset-zone)# member device-alias TARGET2
switch(config-zoneset-zone)# zone commit vsan 10
switch(config)# zoneset activate name Zoneset_10 vsan 10
switch(config)# zone commit vsan 10
Command Explanation:
| Command |
Explanation |
| switch#conf t |
Enters configuration terminal |
| switch(config)# device-alias database |
Enters Device-alias database configuration mode. Allows for the creation, deletion and modification of device-aliases |
switch(config-device-alias-db)#device-alias name HOST pwwn 21:01:00:e0:8b:39:a9:07 |
Assigns the device alias HOST to the pwwn 21:01:00:e0:8b:39:a9:07 . A device-alias can only be mapped to 1 PWWN and a PWWN can only map to 1 device-alias. This is case sensitive. |
| switch(config-device-alias-db)#exit |
Exits device-alias database configuration mode |
| switch(config)#device-alias commit |
Commits device-alias changed |
| switch(config)# zoneset name Zoneset_10 vsan 10 |
Enters Zoneset configuration mode. Creates Zoneset_10 for vsan 10 if it does not exist |
| switch(config-zoneset)# zone name Host_A-Target_1 |
Enters in-line Zone configuration mode. Creates zone Host_A-Target_1 in vsan 10 and as a member to Zoneset_10 if it does not exist |
| switch(config-zoneset-zone)# member device-alias HOST |
Add pwwn as a member of zone Host_A-Target_1 |
| switch(config-zoneset-zone)# member device-alias TARGET1 |
Add pwwn as a member of zone Host_A-Target_1 |
| switch(config-zoneset-zone)# zone commit vsan 10 |
Commits the changes made to the zones and zoneset in vsan 10. Used only if enhanced zoning is enabled |
| switch(config)# zoneset activate name Zoneset_10 vsan 10 |
Sets the active zoneset as the currently configured Zoneset_10 in vsan 10. Note that only 1 zoneset can be active in a vsan at a time |
| switch(config)# zone commit vsan 10 |
Commits the change made to the zoneset in vsan 10. This step is required in enhanced zoning mode after an activation in order for the new activation to occur |
