Fix-Dell iDRAC error: RAC0218: The maximum number of user sessions is reached

You can still ssh to your iDrac, after login,

Run the command:

racadm racreset

If you can access the server physically:

Hold in the “I” on the front of the server (near the power button) for about 20 seconds it will force a reset of the iDRAC. You’ll hear the fans speed up during this process but after a few mins you’ll be able to remotely access your iDRAC again.
