Administrator Guide

NOTE: If the server has physical iSCSI HBAs, Unisphere Central may not automatically recognize the WWNs for the
server. In this situation, configure the iSCSI HBA(s) to target the Storage Center, create a server on the Storage
Center, then manually map the Storage Center server to the Server Agent.
9. Select a parent folder for the server in the Folder navigation tree.
10. To register a VASA provider, select the Register VASA Provider check box.
A VASA provider must be registered to use VMware virtual volumes (VVols) in your storage environment.
a. Select the version of VASA to use:
● Select VASA 1 for an ESXi 5.5 host. The format of the URL for VASA 1.0 is https://host ID:3034/vasa-
provider/vasa1/vasa-version.xml
●
Select VASA 2 for an ESXi 6.0 or later host. The format of the URL for VASA 2.0 is https://host ID:3034/
vasa-provider/vasa2/vasa-version.xml
The host ID is either the IP address or the Fully Qualified Domain Name (FQDN) of the host on which the Data Collector
is installed.
CAUTION: The host must use an FQDN known by DNS so that IP address changes do not cause vCenter
to lose connection to the VASA provider. If FQDN use is not possible, IP address changes will not
automatically be known by vCenter, and unregistering and reregistering the VASA provider will be
required after each change. For this reason, nonphysical address locked DHCP addressing is discouraged.
NOTE: If the VASA provider is unregistered and reregistered, the option for selecting VASA1 or VASA2 during VASA
registration no longer displays because the Storage Manager Data Collector automatically selects the latest version
of VASA that is supported by the ESXi host.
b. Type the user name and password of the Unisphere Central associated with the VASA provider.
CAUTION:
The user name for the VASA Provider should be a service account, not a user account. If a user
account is specified in this field, and the user is deleted, the VASA information could be lost.
11. Click OK.
Results
NOTE:
After a Unisphere Central update, the VASA version number displayed in vCenter is not updated unless the VASA
provider is unregistered and reregistered with that vCenter.
NOTE: If the VASA provider loses network access to the external database, the VASA provider needs to be unregistered
and reregistered to continue with VVols operations.
