Register the VASA Provider
You can register the VASA provider on a vCenter server, and manage it from the Servers view of Storage Center.
Register the VASA provider using one of the following methods:
● When initially registering a vCenter Server in the Unisphere Central client, select the Register VASA Provider check box.
● For a vCenter Server that is already registered in the Unisphere Central client, select Edit Settings and then select the
Register VASA Provider check box.
NOTE: After a software update, the follow error might occur:
Error registering VASA provider: Error running VMware method
[Method: RegisterVasaProvider] [Message: The VASA provider did not
respond]
Follow these steps to fix the error and register the VASA provider:
1. Open the file :msaservice\plugins\module_manager\product-metadata.json .
2. Change the VASA status to deploy.
3. Restart the Data Collector.
Unregister a VASA Provider
Unregister a VASA provider to remove it from vCenter.
Prerequisites
CAUTION:
The VASA provider must be unregistered before you 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 affects control plane operations on virtual volume VMs and datastores which are in use.
It does not affect data transfer between an ESXi host and the respective SAN storage.
Unregistering the VASA provider results in powered-off 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-off 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 Certificates With VASA Provider
When you run the Register VASA Provider wizard, the URL of the VASA provider is automatically generated. This URL
identifies the host on which the Data Collector is installed. The host is identified as either an IP address or fully qualified 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 certificates.
