Configuring a Virtual Device
A virtual device is identified by an alphanumeric name of up to 32 characters and defines all the real devices (one primary and one or more secondary) that it represents. Upon the successful creation of a virtual device, the virtual device name is internally registered as the device alias name with the device alias database; the pWWN is automatically assigned by the system using Cisco OUI (Organizational Unique Identifier). A virtual device appears as a real, physical device. You can enumerate up to 128 devices for a virtual device. There is a limit of 1K on the number of virtual devices that you can create in a single VSAN.
To configure a virtual target and commit it to the fabric configuration using Fabric Manager, follow these steps:
- Expand SAN in the Logical Domains pane. Then expand the fabric in which your VSAN resides.
- Expand the VSAN in which you wish to create the virtual target and select SDV. You see the switches in the VSAN that you selected listed in the Information pane.
- In the Control tab, select enable from the dropdown menu in the Command column to enable SAN device virtualization for a particular switch in the VSAN.
- Click the Apply Changes icon to commit the configuration change.
- Click the CFS tab. Confirm that the SAN device virtualization feature is enabled for the switch.
- Click the Virtual Devices tab and then click the Create Row icon.
- Select the Virtual Device ID from the drop-down list (ranges from 1 to 4096).
- Enter a Name for the Virtual Device. Select the Virtual Domain and enter a Virtual FC ID for the virtual target.
- Click Create to create the virtual target.
- Click the CFS icon to commit and distribute the configuration changes.
To link a virtual target with a physical target using Fabric Manager, follow these steps:
- Click the Real Devices tab and then click the Create Row icon.
- Select the Virtual Device ID from the pull-down list or enter an existing ID for the virtual target that you are linking with a physical target.
- Select the Real Device ID of the physical target that you are linking with the virtual target.
- Choose either the pWWN or deviceAlias radio button, and select the appropriate pWWN or device alias from the pull-down menu. Note that the Name field is automatically populated when you select the pWWN or device alias.
- Choose either the primary or secondary radio button for the Map Type.
- Click the CFS icon to save and distribute these changes, or click Close to discard any unsaved changes.
