Handing over the shutdown control to RCCMD using a vCenter
Menu: VMware Settings
The vCenter differs with its operating modes from a standalone host. While the Standalone Host works on its own and shuts
down virtual machines as needed, vCenter provides the so-called vMotion: The HA - High Availability - of vMotion allows virtual
machines to be moved from one host to another before the host is intentionally powered down.
Please note:
Before you can use the RCCMD appliance with vMotion, the Distributed Resources Scheduler DRS must be configured to use
the fully automatic mode.
Note
Before using RCCMD in conjunction with vMotion, ensure to verify that each virtual machine running on the host has been
tested working with the maintenance mode. If maintenance mode fails, non-migrated virtual machines will be switched off when
the host is powering down.
Open VMware Settings:
If you have not yet made any settings, RCCMD will inform you that RCCMD needs additional information:
Although RCCMD is installed as a virtual machine and is already ready for use, it cannot yet fulfill its actual function since the
necessary access authorizations have not yet been stored. Confirm this message with OK to open the VMware settings:
While using a vCenter, virtual machines can
migrate to another host before the original host
powers down. The virtual machines them self will
continue working seamlessly. Please note the
different access data:
Under Virtual Machine Behavior, select
Maintenance Mode (vMotion).
The Maintenance Mode time out in Seconds defines the time vCenter is given to move a virtual machine to another host. The
behavior of vMotion is configured within the high availability (HA) within the vCenter. As soon as time is up, the standard
shutdown procedure will be initiated:
remaining virtual machines will shut down due to the fact the host powers down.
