Multi-chassis management dashboard
Multiple chassis are grouped to form domains called Multi-Chassis Management (MCM) groups. An MCM group can have 20
chassis, where one is the lead and the remaining 19 are members. OME–Modular supports wired MCM groups where the chassis
are daisy-chained through a redundant port on the management controller.
In a multi-chassis management (MCM) group, the number of events and jobs for the entire group is displayed. The Device
Health, Alerts, and Recent Activity sections display the consolidated details of all the devices in the group.
NOTE: Maintain a minimum interval of two minutes between removing and inserting each device.
Viewing MCM home page
You can view the following information about the MCM group:
● MCM group—You can view:
○ Name of the group
○ Topology of the group using View Topology
○ Name, IP address, and service tag of the lead chassis
○ Name, IP address, and service tag of the member chassis
● Device Health—Displays the health status of the chassis subsystems—chassis, compute sled, networking, and storage.
You can click the health status of the individual devices or click All Devices, to view a summary of the devices in the All
Devices page.
● Recent Alerts—Displays the most recent alerts for events occurring in the lead chassis and the subsystems. Click All
Alerts, to view the Alerts page for the lead and member chassis.
● Recent Activity—Displays the most recent activities occurring in the lead chassis and the subsystems. Click All Activity,
to view the Jobs page for the lead and member chassis.
NOTE:
If a member chassis is added to a chassis group based on a "Join Group" request from the member chassis, the
status of the member chassis is displayed as "Unknown" for some time, on the MCM dashboard.
Viewing lists of chassis in an MCM group
On the OME–Modular home page, the list of chassis that are part of the group is displayed on the left. The list displays the
model, IP address, and the Service Tag of the chassis. The lead chassis is labeled for easy identification. Click the name of the
chassis to access the details specific to the chassis. You can also use the listed IP address to directly access the OME–Modular
web interface of the chassis.
Viewing device health
The Devices > All Devices page displays the health summary of the chassis, compute and storage sleds, and networking
components.
A list of all the devices at the bottom of the All Devices page. You can select a device to view its summary on the right side of
the list. You can sort the list using Advanced Filters.
You can also perform the following tasks on the All Devices page:
● Power control
● Update firmware
● Blink LED
● Refresh inventory
NOTE:
When you initiate a Leave chassis group request while the inventory refresh is in-progress, an error message is
displayed on the All Devices page even if the Leave Chassis Group task is successful.
NOTE: When a compute sled is inserted into a chassis, sometimes the message, "No device image found", is displayed. To
resolve the issue, refresh the inventory of the compute sled, manually.
NOTE: When you refresh inventory and power the chassis on after the chassis is AC power cycled, the inventory of the
compute sled and IOM may be displayed after 3-5 minutes.
