• If the Remove Image Streamer Appliance task on the SERVERS > Enclosures screen terminates with an error, follow the
resolution suggested as part of the error message.
• If an active appliance module is removed, the standby appliance module takes over. It might take 3 to 5 minutes for the
failover to complete. Rarely, this failover operation might take up to 10 minutes to complete. During this time, the Image
Streamer user interface displays the following screen:

Reinserting Image Streamer
When an appliance module component fails or an appliance module is removed, alerts notify you about the failure or removal
on the Activity screen of the Image Streamer user interface.
NOTE: You must shut down an appliance module using the appliance maintenance console before removing it. If you are
powering down an active or standby appliance module, use the appliance maintenance console. If you are powering down both
the appliance modules, you can use the Image Streamer user interface or the appliance maintenance console.
When you reinsert a repaired appliance module or the same appliance module, check Image Streamer task status in the
SERVERS > Enclosures screen using the HPE OneView user interface.
Do not attempt to remove the inserted appliance module before the insert operation is complete because doing so might
interrupt cluster formation. Removing an appliance module during the cluster formation process might render existing OS
volumes inaccessible.
