Configure a vCenter server connection and register the VASA provider

Configuring a vCenter server connection can be completed either during or after the Initial Configuration wizard.

Prerequisites

  • Using a vCenter user with the Administrator role and privileges is recommended when configuring a vCenter Server connection in PowerStore Manager.
  • Alternatively, you can use a vCenter user with the minimum privileges set to Storage Views > Configure service and Storage views > View.
    NOTE:PowerStore Manager only displays data for vCenter objects that vCenter user role used to configure the vCenter connection can access.

About this task

A PowerStore cluster can serve storage to multiple instances of vSphere.
  • If using a self-signed VASA certificate on PowerStoreOS 3.5 or later, you can register multiple vCenter servers in PowerStore Manager. See Manually register multiple vCenter servers using the self-signed certificate for more information.
  • If using a self-signed VASA certificate on a PowerStoreOS version earlier than 3.5, only one vCenter server can be registered in PowerStore Manager.
  • If using a VMCA root certificate, only one vCenter server can be registered in PowerStore Manager.
  • If using a third-party VASA certificate (PowerStoreOS 3.5 and later), you can register multiple vCenter servers with PowerStore if they all use the same root VASA CA certificate. For more information about registering multiple vCenter servers with PowerStore with a third-party certificate, see Manually register the VASA provider in vCenter.
NOTE:During the Initial Configuration wizard, you can opt to retain the PowerStore self-signed VASA certificate when configuring the vCenter server connection by enabling the Retain VASA Certificate option. Otherwise, the vCenter VMCA certificate or third-party VASA certificate is used. After initial configuration, VASA certificate settings can be modified under Settings > Security > VASA Certificate in PowerStore Manager.

Steps

  1. Select Compute > vCenter Server Connection in PowerStore Manager.
  2. Click Connect. The vCenter server configuration slide-out panel displays.
    1. Under vCenter Server Configuration, complete the following fields:
      • vCenter Server IP Address/Host Name
      • vCenter Username
      • vCenter Password
    2. Under vCenter Server Configuration, select the Verify SSL server certificate checkbox to enable PowerStore to validate the vCenter Server certificate upon registration (recommended).
    3. Under VASA Registration, complete the following fields:
      • PowerStore VM Administrator User for PowerStore for VASA provider registration
      • Password of the PowerStore VM Administrator User
    NOTE:The default PowerStore admin user role has VM Administrator privileges. If you do not have a user account with VM Administrator role privileges, add a VM Administrator user in PowerStore Manager.
  3. Click Connect.
  4. If you selected Verify SSL server certificate, additional information for the vCenter SSL certificate is displayed. Review the certificate information, then click Confirm.
    NOTE:The machine SSL certificate appears in vCenter as __Machine_Cert. For more information about vCenter certificates, see the VMware documentation. For more information about viewing and verifying certificates, see the PowerStore Security Configuration Guide.

Next steps

  • To update the stored IP address or credentials for vCenter Server on a PowerStore cluster, click Update Configuration.
    NOTE:You cannot change the vCenter server that a PowerStore cluster is connected to by updating the IP address. To change the vCenter server, see Change a vCenter Server connection.
  • To disconnect the vCenter Server from a PowerStore cluster and unregister the VASA provider, click Disconnect.
    NOTE:You can no longer use the PowerStore cluster to manage VMs after the vCenter Server is disconnected.
