Virtualization 97
Second Type of Nodes (DELL MUMC Detects Dell ULNM Running on the VMHost)
If there is a Dell ULNM installed on the server that is hosting the Hypervisor (VMHost), the shutdown is
done by the Dell ULNM.
In this case, the node contains both parameter types:
• The remote maintenance mode feature parameters.
• The Dell ULNM shutdown parameters (as a Dell ULNM will perform the shutdown locally).
NOTE: All the parameters are retrieved from Dell ULNM, and you will configure the Dell ULNM from Dell MUMC in
the Node Configuration Panel. See “Nodes Settings” on page 64 for more information on using the
configuration interface.
The Shutdown Settings are (see Figure 79):
• Remote Maintenance: Enabled or Disabled. When enabled, the Dell MUMC client sets the host to
“Maintenance Mode.” Depending on your host/cluster configuration, this can trigger vMotion/live
migration to another host. This event is triggered at the time set in the “Maintenance Timer” option
(below).
•
Maintenance Timer: Time elapsed “on battery state” before the Dell MUMC script changes the state
of the host to maintenance mode.
NOTE: The -1 value means the timer is disabled. See “Configuring Maintenance Mode and vMotion with vCenter”
on page 113 and “Configuring Maintenance Mode and Live Migration with SCVMM” on page 116 for more
information.
• Remote Shutdown: Enabled or Disabled (When enabled, it allows Dell MUMC to gracefully
shutdown this server in case of “UPS on battery state” and Shutdown criteria reached)
•
Remote Shutdown of the Virtual Machines: Enable Dell MUMC to shutdown the Virtual Machines
•
Power Source: UPS powering this server (this node has to exist already in Dell MUMC)
•
Load Segment: UPS load segment powering the server
•
(NMC Access) Login/Password: Network Management Card Login/Password that allows Dell ULNM
software to control NMC shutdown sequence.
•
Master - Shutdown Duration: Server Shutdown criteria (time needed for graceful host shutdown)
•
Master - Shutdown After Value: Server Shutdown criteria, which s the time elapsed “on battery state”
before graceful Shutdown. (This timer must be greater than the maintenance timer)
NOTE: The -1 value means the timer is disabled.
• Power Source Shutoff: Disabled. Enabled is used only for server connected with UPS though RS-232
or USB. Virtualization behavior requires Ethernet connectivity (Dell Network Management Card).
