Rebooting the System
Reboot the ztC Edge system using the ztC Console to safely restart both PMs without affecting VMs. On a single-node system, reboot the system only during a planned maintenance period, since the Virtual Machines are shut down and restarted during the reboot.
Caution: Rebooting the ztC Edge system by any method other than following (for example, rebooting from the PMs individually) may result in data loss.
Note:
You can reboot a system licensed for two PMs only if both PMs are running, healthy, and not in maintenance mode. You can reboot a system licensed for one PM only if the PM is running, healthy, and not in maintenance mode.
Prerequisite:
On a system licensed for two PMs, confirm that both PMs are running before rebooting. On a single-node system, confirm that the one PM is running before rebooting.
To reboot the ztC Edge system
- Select System in the left-hand navigation panel.
-
Click the Reboot button. A message appears, asking you to confirm the reboot. Click Yes to continue.
Rebooting can take up to 15 minutes. You can observe the process in the Dashboard and the masthead of the ztC Console. The system's PMs sequentially enter and then exit maintenance mode (for information on maintenance mode, see Maintenance Mode).
- Verify that the PMs restart and that all VMs continue running as expected.
After you initiate a reboot, a message in the masthead shows the status of the reboot. If necessary, you can cancel the reboot by clicking Cancel Reboot in the masthead.
Caution: If you cancel a reboot, the system is left in its current state and you need to manually restore it to a healthy state.
