In the server's Attached Media screen, disconnect the iDRAC Remote File
Share from the iDRAC browser.
l
Disconnect the iDRAC remote image:
racadm -r <dracIP> -u root -p <password> remoteimage –d
Where:

<dracIP>
 is the iDRAC IP address
n
<password>
 is the password for the server
Note:
The default password is calvin for 13G nodes and Scaleio123 for 14G nodes.
