Updating Device location
OMPC enables you to replicate and update the physical organization and hierarchy of a data center.
Using OMPC you can place servers in the hierarchy specified on iDRAC/CMC. Only servers for which the values have been
populated in the following hierarchy Data Center, Room, Aisle, and Rack fields are automatically assigned in OMPC. The
servers remain unassigned, if any of the values are missing in the hierarchy.
The iDRAC/CMC location can be updated from a group level following the physical hierarchy Data center, Room, Aisle, and
Rack. OMPC updates the location of the devices present in a particular group, such as a data center, room, aisle, or a rack.
NOTE: The location can be updated only for chassis, rack, and tower (only Dell servers).
1. In the left pane, click Devices > Managed Group
2. From the list of device groups, select a data center, room, aisle, rack, or a device in the rack.
The details of the device are displayed in the Details section
3. Click Update Device Location.
The Device Location Update Window is displayed.
4. Click Update to update the device location with the iDRAC/CMC location.
NOTE: If the iDRAC/CMC path and the device path are not synchronized, a warning message is displayed in the Details
> Device Details section. You may have to update the device path to ensure that it is synchronized with the
iDRAC/CMC path.
A table is displayed providing information about the successful location update. If the update is not successful, you can view
the application logs for details about the failure.
5. Click Close.
Chained PDU Support
In a data center, you can use any number of PDUs for power distribution, depending on the infrastructural requirements. The
PDUs can be connected in a daisy chain manner to further enhance and improve the power distribution in the data center. In the
daisy chain arrangement of PDUs, a master PDU discovers and monitors the subordinate PDUs. Currently, only the master PDUs
are discovered, but the subordinate PDUs connected are not discovered, hence monitoring the power aspects of those PDUs
are not possible.
Starting OMPC 3.2, you can also discover, monitor, and perform all operations on the subordinate PDUs as it is done on a
master PDU. The daisy chained PDUs are discovered using the IP address, irrespective of whether the same SNMP port is used
(for both master and the subordinate) or not. Adding a daisy chained PDU to a rack automatically associates the subordinate
PDUs to that particular rack. However, you can also associate or disassociate a subordinate PDU from the master PDU
individually.
NOTE:
If you disassociate a subordinate PDU from the master PDU, it is removed only from that particular daisy chain
arrangement.
NOTE: Deleting a master PDU does not delete the associated subordinate PDUs.
Viewing chained PDUs
1. In the left pane, click Devices > All Devices.
2. From the list of devices, select a PDU device.
3. If the selected PDU is a Master PDU, Associate Subordinate PDU option is displayed.
4. Click on the Associate Subordinate PDU option to view the associated subordinate PDU.
The sequence of the associated PDUs, PDU name, PDU model, Service tag, and the time of discovery is displayed.
5. If the selected PDU is a subordinate PDU, Associate Master PDU option is displayed.
6. Click on the Associate Master PDU option to view the associated master PDU.
The PDU name, PDU model, Service tag, and the time of discovery is displayed.
