Troubleshooting I/O Modules
To eliminate the possibility of a hardware issue with the module or its attaching devices, make sure
that the module is properly initialized and configured.
Make sure that you have installed the module in an I/O slot that matches its fabric type. Check that
the pass-through or switch module is cabled correctly.
For switch modules (pass-through modules are non-managed), run the Connect Switch command
to verify that the switch is fully started, and verify the firmware revision and IP address of the
switch. Verify that the switch module has a valid IP address for the subnet. Verify using the ICMP
ping command. Check the network connector indicators on the network switch module.
If the link indicator displays an error status, check all cable connections. Try another connector on
the external switch or hub. If the activity indicator does not illuminate, replace the network switch
module.
Using the switch management interface, verify the switch port properties. If the switch is configured
correctly, back up the switch configuration and replace the switch. See the switch module
documentation for details. If the network link indicator for a given server is green, then the server
has a valid link to the appropriate network switch module.
Make sure that the appropriate operating system drivers are installed and that the protocol settings
are configured to insure proper communications.
Resetting Components
VRTX Chassis CMC module can be reset using reset components, reset iDRAC without restarting the
operating system, or to virtually reseat servers causing them to behave as if they were removed and
reinserted. If the chassis has a standby CMC, resetting the active CMC causes a failover and the
standby CMC becomes active.
To reset components, you must have the administrator privilege. To reset the components using the
CMC Web interface, select Chassis Overview > Troubleshooting > Reset Components.
To reset the active CMC, in the CMC Status section, click Reset/Failover CMC. If a standby CMC is
present and a chassis is fully redundant, a failover occurs causing the standby CMC to become active.
The same can be achieved by running the RACADM command racadm cmcchangeover.
To reset an iDRAC without restarting the server operating system, in the Reset Server section, click
iDRAC Reset in the Reset drop-down menu for the servers, whose iDRAC you want to reset, and then
click Apply Selections. This resets the iDRACs for the servers without restarting the operating
system. To reset only an iDRAC without restarting the operating system using RACADM, see the
Chassis Management Controller for PowerEdge VRTX -RACADM Command Line Reference Guide.
When an iDRAC is reset, fans are set to 100% for the server that may cause the blowers to increase in
speed for a short period of time, which is normal. It is recommended to try resetting the iDRAC
before you attempt to virtually reseat the servers.
