> # Decommissioning a Host

> ## Detailed Steps

> To decommission an existing host, follow these steps:

> 1. From the DCNM-SAN window, select Tools > Host Provisioning.

> The Select Host window appears.

> 2. Click the Decommission radio button.
> 3. Click [...] and select the host from the existing configurations or VSAN, or enter the WWN of a host that is not in VSAN.

> The device alias and DPVM state from all of the switches in the selected VSAN are populated if device alias with CFS and CFS DPVM are enabled and if the WWN is an eight-byte number.

> 4. Click Finish. The device aliases are removed.
> 5. Uncheck the Skip Zoning check box.

> The WWN zone member is removed from all zones. If the zones without a WWN member become single member zones, these zones also are removed.

> 6. Click Finish. If there is a local active zone set change due to the removal of zones, the appropriate zone set is activated.
> 7. Uncheck the Skip DPVM check box.
> 8. Click Finish. The DPVM entry is removed.
> 9. Click Next.

> The Decommission Zones window appears.

> 10. Check the Remove Flow after Deactivation check box.

> The flow entry associated with the host is removed when you click Finish.

> 11. Click Finish.

> The device alias and DPVM entries are deleted, the zone is deactivated and deleted (if it has only one member after removing the host), and the flow is deleted depending on the check boxes you checked.
