Dell R720 iDRAC reset

Hi,

I encounter a small problem with a customer.

We have some Dell PowerEdge R710 and R720 servers used for ESXi Hypervisor, we use the iDRAC 7 for manage and monitor some parts of the server.

On three of them, we cannot access the iDRAC web interface, and i search a trick to reset the iDRAC.

We can to ping or access by SSH to the iDRAC ip address, but i cannot find the right SM-CLP command to reset only the iDRAC.

These servers is in production and we cannot shutdown them.

Thanks you for your return.

Best regards and sorry for my swiss english ;)
