Chapter 26 Using Storage Providers• Alarms indicate a change in <strong>storage</strong> system availability. For example, when you use profile-based<strong>storage</strong> management, you can specify virtual machine <strong>storage</strong> requirements. When changes tounderlying <strong>storage</strong> occur that might violate the <strong>storage</strong> requirements of the virtual machine, an alarmgets triggered.For more information about events and alarms, see the vSphere Monitoring and Performance documentation.Thin-provisioned LUNs have special reporting requirements. For information about space monitoring onthin-provisioned LUNs, see “Array Thin Provisioning and VMFS Datastores,” on page 249.Register Storage ProvidersTo establish a connection between the vCenter Server and a <strong>storage</strong> provider, you must register the <strong>storage</strong>provider.NOTE If you use Virtual SAN, the <strong>storage</strong> providers for Virtual SAN are registered and appear on the list of<strong>storage</strong> providers automatically. See “View Virtual SAN Storage Providers,” on page 189. If fortroubleshooting purposes you need to remove or unregister the Virtual SAN <strong>storage</strong> providers, you can usethis procedure to register them manually. Make sure to register a separate <strong>storage</strong> provider for each host inthe cluster.PrerequisitesVerify that the <strong>storage</strong> provider component is installed on the <strong>storage</strong> side and obtain its credentials fromyour <strong>storage</strong> administrator.Procedure1 Browse to the vCenter Server in the vSphere Web Client navigator.2 Click the Manage tab, and click Storage Providers.3 Click the Register a new <strong>storage</strong> provider icon.4 Type connection information for the <strong>storage</strong> provider, including the name, URL, and credentials.For the Virtual SAN <strong>storage</strong> provider, enter a separate URL for each host that participates in the cluster.http://host_ip:8080/version.xml, where host_ip is the actual IP of the host.NOTE The Virtual SAN <strong>storage</strong> provider is a non-SSL provider. This means that the traffic betweenSMS and the Virtual SAN <strong>storage</strong> provider does not need to be secured by a valid user name andpassword. However, when registering the Virtual SAN provider, you must provide some values for theUser Name and Password fields because these fields are mandatory on the registration dialog box. Anyvalues are accepted because the Virtual SAN <strong>storage</strong> provider does not perform any real validation andignores these credentials.5 (Optional) To direct the vCenter Server to the <strong>storage</strong> provider certificate, select the Use StorageProvider Certificate option and specify the certificate's location.If you do not select this option, a thumbprint of the certificate is displayed. You can check thethumbprint and approve it.This step is not valid for Virtual SAN and is optional for all other types of <strong>storage</strong> providers.6 Click OK to complete the registration.The vCenter Server has registered the <strong>storage</strong> provider and established a secure SSL connection with it.VMware, Inc. 2<strong>55</strong>
