VSAN Configuration Structure
| VSAN database | vsan database | switch(config-vsan-db)# | VSAN database |
| Zone | zone name string vsan vsan-id | switch(config-zone)# | Zone member |
| Zone set | zoneset name name vsan vsan-id | switch(config-zoneset)# | Zone set member |
| Fibre Channel Alias | fcalias name name vsan vsan-id | switch(config-fcalias)# | Alias member |
Create vsan
| Command | Purpose |
|---|---|
| switch# config t | Enters configuration mode. |
| switch(config)# vsan database switch(config-vsan-db)# | Configures the database for a VSAN. Application specific VSAN parameters cannot be configured from this prompt. |
| switch(config-vsan-db)# vsan 2 switch(config-vsan-db)# | Creates a VSAN with the specified ID (2) if that VSAN does not exist already. |
| switch(config-vsan-db)# vsan 2 name XXXX updated vsan 2switch(config-vsan-db)# | Updates the VSAN with the assigned name (XXXX). |
Configuring Zones and Zone Sets
Configuring an Alias
| Command | Purpose |
| switch(config)# fcalias name AliasXXXX vsan 3 switch–config-fcalias# | Configures an alias name (AliasXXXX). |
| switch-config-fcalias# member pwwn 10:00:00:23:45:67:89:ab | Configures alias members based on the specified port WWN type and value (pWWN 10:00:00:23:45:67:89:ab). |
Configuring Zones
| Command | Purpose |
| switch(config)# zone name Zone1 vsan 3 switch(config-zone)# | Configures a zone called Zone 1 for the VSAN called vsan3. |
| Switch(config-zone)# member <type> <value> pWWN example: sswitch(config-zone)# member pwwn 10:00:00:23:45:67:89:ab | Configures a member for the specified zone (Zone1) based on the type (pWWN, fabric pWWN, FC ID, FC alias, domain ID, IP address, or interface) and value specified. |
| FC alias example: switch(config-zone)# member ipaddress 10.15.0.0 255.255.0.0 | |
| Local sWWN interface example: switch(config-zone)# member interface fc 2/ | |
Creating Zone Sets
| Command | Purpose |
| switch(config)# zoneset name Zoneset1 vsan 3 switch(config-zoneset)# | Configures a zone set called Zoneset1. Tip To activate a zone set, you must first create the zone and a zone set. |
| switch(config-zoneset)# member Zone1 | Adds Zone1 as a member of the specified zone set (Zoneset1). Tip If the specified zone name was not previously configured, this command will return the Zone not present errormessage. |
| switch(config-zoneset)# zone name InlineZone1 switch(config-zoneset-zone)# | Adds a zone (InlineZone1) to the specified zone set (Zoneset1). Tip Execute this step only if you need to create a zone from a zone set prompt. |
| switch(config-zoneset-zone)# member fcid 0x111112 switch(config-zoneset-zone)# | Adds a new member (FC ID 0x111112) to the newly created zone (InlineZone1). Tip Execute this step only if you need to add a member to a zone from a zone set pr |
Activating a Zone Set
| Command | Purpose |
| switch(config)# zoneset activate name Zoneset1 vsan 3 | Activates the specified zone set. |
After creating a zone set and activating it make sure you save the configuration file.
