- Enter Maintenance Mode:Place a host into maintenance mode. Afterwards, you can disable or repair the host. After the host is confirmed to enter maintenance mode, if your primary storage where the host is running is LocalStorage, ZStack will disable all running VM instances residing on the host. If your primary storage where the host is running is a shared storage, VM instances will automatically be migrated to other hosts.
Note:
- Under the shared storage scenario, after the host enters maintenance mode, you can set the VM migration policy in case of migration failure.
- Method:Go to, locate host.maintenance.policy, and click the Edit icon.
- If you select Stop Vm On Migration Failure, VM instances that are running on a shared storage will be automatically migrated to other hosts after the host where the VM instances reside enters maintenance mode. In addition, VM instances that fail to be migrated will be forced to stop.
- If you select Just Migrate, VM instances that are running on a shared storage will be automatically migrated to other hosts after the host where the VM instances reside enters maintenance mode. If some VM instances are still running on the host, the host will fail to enter maintenance mode.
- Disable:
Stop a host. Afterwards, new VM instances cannot be created on the host, and the stopped VM instances on the host cannot be started. Currently, the running VM instances are not affected.
