Retiring lead chassis

You can use the retirement process of the existing lead chassis to make it a member chassis of the existing group or a stand-

alone chassis.

1. On the MCM dashboard, click Configure > Retire Lead Chassis.

The Retire Lead Chassis window is displayed.

2. Select one of the following options:

● Make it a member of the current group.

● Make it a stand-alone chassis.

3. Click Retire.

Also, see the section, Use case scenarios.

Any existing firmware baselines on the old lead chassis are imported to the new lead during retire, and a firmware compliance

check job is initiated. Owing to rediscovery ordering of chassis during retire, the old lead is on-boarded after the compliance

check for imported firmware baselines is completed. The ordering excludes the devices in the old lead chassis from the

baseline report. To resolve this limitation, rerun the compliance check on the promoted lead after the retire job is completed

so that the old lead devices are listed in the compliance or baseline report.

MCM dashboard

The MCM dashboard is displayed only when a multi-chassis management (MCM) group is created. You can view the name of

MCM group on the left side of the dashboard. Below the group name, you can view the names, IPs, and service tags of the lead

and member chassis. The lead chassis is indicated by the "LEAD" on the right side of the chassis name and the backup chassis is

indicated by "BACKUP".

Click View Topology to view the structure of the MCM group.

The mid section of the MCM dashboard displays the health summary of all chassis, compute, networking, and storage devices in

the MCM group. You can view the list of all the devices in the group by clicking All Devices at the upper right corner of the

dashboard.

Below the health summary, you can view the alerts that are based on criticality of the alert and device type. Click All Alerts to

view the list of the alerts that are related to all events in the MCM group.

You can view the details of the recent activities that are related to the group on the right side of the dashboard. The details

comprise of the name and status of the activity, and timestamp of the activity. Click All Activity to view a list of all the

activities that are related to the group, on the Jobs page.

Controlling chassis power

You can turn on and turn off the chassis power supply from the OME–Modular home page.

If you turn off the chassis manually or a power grid failure results in turning off multiple chassis, IOMs, and compute sleds, then,

turning on all the chassis and compute sleds may result in failed inventory jobs for two to three hours. However, the inventory

jobs recover with no impact to the chassis and related components.

To control the chassis power:

1. On the home page, click Power Control and select the required option.

The available options are:

● Power Off (Non-graceful)

● Power Cycle System (Cold Boot)

● Power Off (Graceful)

NOTE:

After login, wait for 7 minutes, if the IP is unavailable, then check if:

○ The cable is connected.

○ DHCP is configured, ensure that the cable is connected to a Top of Rack (TOR) switch that has connectivity to

the DHCP server.

A message is displayed prompting you to confirm your action.
