Removing An Image Streamer - HPE Synergy 813562-001 Maintenance And Service Manual

Only a standby appliance module can be removed from the appliance cluster. To remove an active appliance module from the
cluster, you must activate the standby appliance so that both appliances swap roles.
When the standby appliance module is removed from the cluster and if there is an unused appliance module that is powered
on and available, that unused appliance module assumes the role of the standby appliance module if:
• The unused appliance module is powered on.
• The unused appliance module is the same model as the active appliance module.
• The unused appliance module runs the same version of the software and firmware as the active appliance module.
Otherwise, the active appliance module becomes a standalone appliance module.
IMPORTANT: Removing an appliance module from the cluster resets the appliance to original factory settings and
then powers it off. That appliance cannot join the cluster until it is powered on. For more information, see Powering up
the appliance.
Prerequisites
Minimum required privileges: Infrastructure administrator.
Procedure
1. From the main menu, select Settings, and click Appliance.
2. Use the information on the Appliance panel to determine if the appliance module you want to remove is the active or
standby appliance module.
3. To remove the active appliance module, activate the standby appliance.
At the end of the operation, the appliances have swapped roles so that the previous active appliance module is now the
standby appliance module and the previous standby appliance module is the current active appliance module.
4. Select Actions > Remove standby.
5. Select Yes, remove standby.
6. Verify that the standby appliance module is removed from the cluster either by examining the Appliance panel on the
Settings screen, or by using the View details command of the HPE OneView Maintenance Console. For more
information, see View the appliance details in the HPE OneView User Guide for HPE Synergy on the Hewlett Packard
Enterprise website http://www.hpe.com/info/synergy-docs.
