Knowing devices WWN is necessary to define aliases during zone creation in SAN environments on SAN switches, you need to storage FC ports WWN as targets in each zone. So where you can find device’s FC ports information?
Actually, there is two regular ways:
- GUI Management Tool
- CLI Management Tool
Find FC port WWN is too easy in GUI management tools such as EMC Unisphere and also there is some options to export WWN addresses to some formats like CSV or Excel file.
Here is an example of VNX’s FC ports WWN:
What About EMC Unity
Same as VNX, Unisphere can show list of FC ports and WWN addresses for Unity storage system:
You can see all FC ports status and information on the above page but I couldn’t find any export button, so if you have more than one Unity and you need to have all WWN addresses, how you can export WWN addresses as standard formats such as CSV and others?
UEMCLI (Unity command-line management tool) helps you on this regard, run the below command to find FC ports WWN:
uemcli -d 184.108.40.206 -u local/user /net/port/fc show -filter WWN
Change IP address with your storage IP address and user with your username as well.
The result might be like the below:
You can copy the WWN addresses as text and paste it to your zoning script or anywhere else.
