Viewing Information And Health Status Of The Iom; Viewing Information And Health Status Of Fans - Dell EMC PowerEdge VRTX User Manual

Viewing Information and Health Status of the IOM

To view health status of the IOMs, in the CMC Web interface, do any of the following:
1. Click Chassis Overview.
The Chassis Health page is displayed. The graphics in the left pane displays the rear, front, and side view of the chassis and
contains the health status for the IOM. IOM health status is indicated by the overlay of the IOM sub-graphic. Move the cursor
over the individual IOM sub-graphic. The text hint provides additional information about that IOM. Click the IOM sub-graphic to
view the IOM information in the right pane.
2. Go to Chassis Overview → I/O Module Overview.
The I/O Module Status page provides an overview of IOM associated with the chassis. For more information, see the Online
Help.
NOTE: After updating or power cycling the IOM/IOA, make sure that the operating system of the IOM/IOA is also booted
correctly. Else, the IOM status is displayed as "Offline".

Viewing Information and Health Status of Fans

CMC controls the speed of the chassis fan by increasing or decreasing the fan speed on the basis of system events. You can run the
fan in three modes such as Low, Medium, and High. For more information about configuring a fan, see the Online Help.
To set up the properties of fans by using RACADM commands, type the following command at the CLI interface.
racadm fanoffset [-s <off|low|medium|high>]
For more information about the RACADM commands, see the Chassis Management Controller for PowerEdge VRTX RACADM
Command Line Reference Guide available at dell.com/cmcmanuals.
NOTE: The CMC monitors the temperature sensors in the chassis and automatically adjust the fan speed as needed.
However, you can override to maintain a minimum fan speed by the racadm fanoffset command. When overriden using
this command, the CMC will always run the fan to the selected speed even though the chassis does not require the fans
to run at that speed.
CMC generates an alert and increases the fan speeds when the following events occur:
• CMC ambient temperature threshold is exceeded.
• A fan stops functioning.
• A fan is removed from the chassis.
NOTE: During updates of CMC or iDRAC firmware on a server, some or all of the fan units in the chassis rotates at 100%.
This is normal.
To view the health status of fans, in the CMC Web interface, do any of the following:
1. Go to Chassis Overview.
The Chassis Health page is displayed. The lower section of chassis graphics provides the left view of the chassis and contains
the health status of the fans. Fan health status is indicated by the overlay of the fan sub-graphic. Move the cursor over the fan
sub-graphic. The text hint provides additional information about a fan. Click the fan subgraphic to view the fan information in
the right pane.
2. Go to Chassis Overview → Fans.
The Fans Status page provides the status, speed measurements in revolutions per minute (RPMs), and threshold values of the
fans in the chassis. There can be one or more fans.
NOTE: In the event of a communication failure between CMC and the fan unit, CMC cannot obtain or display the
health status for the fan unit.
NOTE: The following message is displayed when both the fans are not present in the slots or if a fan is rotating at a
low speed:
Fan <number> is less than the lower critical threshold.
