Dell M1000e IOM firmware fails from CMC GUI

When trying to update the IOM firmware from the CMC GUI you see the error below. I tried pulling the standby CMC and vice-versa but this did not work either.

Fix:

Connect to the CMC management IP address via putty over SSH, and issue this command.

racadm fwupdate -s -m all

This should list all the modules that require a firmware update.

racadm fwupdate -u -m iominf-1

The command above will update the IOM is A1, so you will need to repeat this if you have more IOMs, changing the last digit. Be warned this command will reboot the switch!

Dell Blade IOM back door console access

There are three ways to manage a Dell Blade switch.

1. The good old serial console
2. SSH if you have configured the switch with an IP address via method 1.
3. SSH to the CMC IP address with putty, teraterm etc.
   at the $ prompt type:
   $ connect switch-1
4. To exit type CTRL+\

Magic console access to the switch for a remote location without a serial connection, great if you assign the wrong VLAN like I did and get cut off from the switch via SSH :P

switch-1 = A1
switch-2 = A2
switch-3 = B1
switch-4 = B2
switch-5 = C1
switch-6 = C2
