8.8. About Desktop Provider Alarms

8.8.2. Reloading iSCSI or Sun ZFS Storage Configuration on Oracle VM VirtualBox Hosts

The status of desktop provider alarms is displayed at the top of Oracle VDI Manager underneath the Log Out and Help buttons. If there are no current desktop provider alarms in the Oracle VDI environment, the Alarms heading does not display.

The icons next to the Alarms heading change depending on the status of the desktop providers in the Oracle VDI environment. For each alarm state displayed, a counter specifies how many desktop providers are currently in that state. The valid states include:

Each alarm counter is also a link that displays the Desktop Providers page based on the following conditions:

8.8.1. Reconfiguring an Oracle VM VirtualBox Host

In some situations, a VirtualBox host can be marked as unresponsive. This might be due to network connectivity issues or because the host is no longer responding. However, the situation can also occur if the configuration of the host has changed, for example because the host operating system has been upgraded or the VirtualBox software has been updated.

In these situations, the solution is to edit the configuration of the VirtualBox host.

Oracle VDI Manager Steps

  1. In Oracle VDI Manager, select Desktop Providers and then select the desktop provider with the problem.

  2. Click the Host tab.

  3. Select the unresponsive host and click the Edit button.

    The Edit Host window is displayed.

  4. On the Specify New Host step, enter the host details.

    1. In the Host field, enter the fully-qualified DNS name or IP address of the VirtualBox host.

    2. In the SSL Port field, enter the port number to use for SSL communication with the VirtualBox host.

      This is the port that was specified when VirtualBox was installed. The default SSL port is port 443.

      If SSL is not used, deselect Use SSL Encryption.

    3. In the SSH Port field, enter the port number used for SSH connections to the VirtualBox host.

    4. In the User Name and Password fields, enter the credentials of a user with root access to the VirtualBox host.

  5. On the Verify Certificate step, check that the SSH and SSL certificate details are correct and click Finish.

    This is an important security step that ensures you are adding a genuine VirtualBox host to the desktop provider.

    The Edit Host window is closed and a message is displayed to confirm that the host has been updated. After a few moments the status of the host changes to Enabled.

Command Line Steps

  1. Edit the configuration of the provider host using the vda provider-host-setprops command.

    /opt/SUNWvda/sbin/vda provider-host-setprops -h host \
    -p username=username,password-prompt,certificate=update,sshcertificate=update provider
    

    For example:

    /opt/SUNWvda/sbin/vda provider-host-setprops -h vb1.example.com\
    -p username=root,password-prompt,certificate=update,sshcertificate=update MyProvider
    Enter password for user root on host vb1.example.com:
    SSL Certificate: 
                           MD5: 7AA02D6357FE5A2D68DB6484750F6F0E
                       Company: Oracle Corporation
                          City: Redwood Shores
                         State: Ca
                       Country: US
    
    SSH Certificate: 
                          Issued By: vb1.example.com
                                Key: 
                       Finger print: 85:fd:e6:22:3a:13:46:6e:e0:ed:5a:0c:f6:42:ca:76
    
    
    Updated Host Settings
    
  2. Check the status of the provider host using the vda provider-list-hosts command.

8.8.2. Reloading iSCSI or Sun ZFS Storage Configuration on Oracle VM VirtualBox Hosts

In some situations, a storage that uses the Oracle Cluster File System version 2 (OCFS2) file system can be marked as unresponsive. For example, this might happen if there is a problem with the o2cb service or after an operating system upgrade on the host. This applies only to Oracle VM VirtualBox providers on Oracle Linux platforms that are configured to use either iSCSI or Sun ZFS storage.

In these situations, the problem can often be cleared by forcing Oracle VDI to reload the storage configuration for the desktop provider. When you do this, Oracle VDI performs all the normal steps for adding an iSCSI or Sun ZFS storage apart from formatting the OCFS2 file system (the file system is aready formatted). You can only perform this operation if the status of all the virtualization hosts for the provider is Enabled.

Use the following command to reload the storage configuration for a desktop provider:

/opt/SUNWvda/sbin/vda provider-vb-reconfigure provider
