Dell License Manager Version 1.7 User's Guide

Invalid credentials

Message: Unable to establish communications - Access is denied.

Resolution: Enter correct credentials. If iDRACs do not share common credentials, you must run multiple discovery or inventory tasks by using different credentials.

Certificate error

Messages:

• Unable to establish communications - The SSL certificate contains a common name (CN) that does not match the hostname.
• Unable to establish communications - The SSL certificate is signed by an unknown certificate authority.
• Unable to establish communications - The SSL certificate could not be checked for revocation. The server used to check for revocation might be unreachable.
• Unable to establish communications - The SSL certificate is expired.

Resolution: If the certificate name does not match the hostname, install a certificate that matches the address on which the management controller is inventoried. Alternatively, disable the certificate name validation feature in your discovery or inventory settings. For more information, see Communication Settings.

If the certificate authority is not recognized, add the certificate authority to the list of Windows Trusted Root Certification Authorities on the management console. Alternatively, disable the certificate authority validation feature in the discovery or inventory settings. For more information, see Communication Settings.

If you cannot check the certificate for revocation, make sure that the certificate revocation list server is available to the management console. Alternatively, disable the certificate revocation list checking in the discovery or inventory settings. For more information, see Communication Settings.

If the certificate has expired, generate and install a new certificate. Dell License Manager cannot connect to iDRACs by using an expired certificate.

Unable to connect

Messages:

• Unable to ping system - Timed Out
• Unable to establish communications - Connection to host timed out

Resolution: Verify that the management controller is connected to the network and assigned the specified address. Verify that the firewall settings allow you to access the system from the management console.

From the iDRAC or CMC GUI, verify that the address corresponds to a system that contains iDRAC7 or a later version. To access the GUI, connect to the system IP or hostname from a web browser. If the system does not contain iDRAC7, ignore the message.
