Administrator Guide

• The VASA provider does not support user-dened storage proles. Only default system-dened storage proles can be used in VM

Storage Policies.

You can register the VASA provider on a vCenter server, and manage it from the Servers view of Storage Center.

• When initially registering a vCenter Server in the Unisphere Central client, select the Register VASA Provider checkbox.

• For a vCenter Server that is already registered in the in the Unisphere Central client, select Edit Settings and then select the Register

VASA Provider

checkbox.

Unregister a VASA Provider

Unregister a VASA provider to remove it from vCenter.

Prerequisite

CAUTION: The VASA provider must be unregistered before you to initiate any of these tasks:

• Any action related to uninstallation, migration, upgrade, reinstalling of Unisphere Central on same host with same IP address

• Uninstalling Unisphere Central with the intention of reinstalling on another host

• Changing the Unisphere Central FQDN

• Changing the Unisphere Central IP address

Unregistering VASA will aects control plane operations on virtual volume VMs and datastores which are in use. It does not aect data

transfer between an ESXi host and the respective SAN storage.

Unregistering the VASA provider results in powered-o VVol VMs being shown as inaccessible and datastores as inactive. To avoid

prolonged control plane down time, minimize the period where the VASA provider remains unregistered. After re-reregistration, there

could be a delay for powered-o VMs and datastores to recover from being inaccessible and inactive respectively.

Steps

1 Click the Servers view.

2 Select the Servers folder in the Servers pane.

3 Right-click the icon for the vCenter Server, and select Edit Settings.

The Edit VMware vCenter Server Settings dialog box opens.

4 Click Unregister VASA Provider.

5 Click OK.

Using Unisphere Central Certicates With VASA Provider

When you run the Register VASA Provider wizard, the URL of the VASA provider is automatically generated. This URL identies the host

on which the

Data Collector is installed. The host is identied as either an IP address or Fully-Qualied Domain Name (FQDN). Depending

on how you installed or upgraded Unisphere Central or if you changed the host for the Data Collector, you might need to take additional

steps to update the certicates.

New Installation of Dell Unisphere Central

If Unisphere Central is registered with a name lookup service such as DNS server or Active Directory server, Unisphere Central certicates

are generated based on its FQDN. Any IP address changes do not aect certicates. If you change the FQDN, Unisphere Central must be

manually restarted if it is a Windows-based installation. It is automatically rebooted for the Virtual Appliance installation. If you were using

the VASA provider before the IP changes, you must unregister and then register VASA Provider manually.
