Shutting Down and Restarting a Compute Module
From the Hardware page, you can shut down and restart a compute module
A customer-replaceable unit (CRU) located at the front of the ztC Endurance system. It is equipped with processors, RDIMMs, BIOS, BMC, fans, and other technology to boot and run the ztC Endurance system. Each system contains two compute modules.. You do this to perform service operations that require physically removing a compute module from the system.
A ztC Endurance compute module state that suspends module operation so that it can be serviced. When an active compute module enters maintenance mode, the system performs a Smart Exchange, then activates the standby compute module. Compute modules must be in maintenance mode before they are shut down.
Note that placing a ztC Endurance compute module into maintenance mode is unrelated to placing an ESXi host into maintenance mode. before you shut it down. For information about entering a compute module into maintenance mode, see Using Maintenance Mode. To shut down a compute module
-
From the Hardware page, select a compute module that is in maintenance mode.
-
Click Shutdown.
-
Click Yes on the Confirm window.
When the compute module has been shut down, its state appears as Maintenance Mode, and its Activity displays as Shutdown. At this point, it is safe to remove the compute module.
To restart a compute module
-
From the Hardware page, select a stopped compute module.
-
Click Boot.
-
Click Yes on the Confirm window.
After the compute module completes its restart, its state still appears as Maintenance Mode, and its Activity displays as Running.
