An OpenManage Enterprise administrator is performing updates using the out-of-band method but the task fails. The iDRAC logs show that the job was scheduled successfully, but the firmware download task failed. The network team has determined that a firewall setting is the problem.

D.
iDRAC access is blocked to the Internet
Answers
D.
iDRAC access is blocked to the Internet
Suggested answer: D

Explanation:

When performing out-of-band updates using OpenManage Enterprise and the task fails due to a firewall setting, despite the iDRAC logs indicating that the job was scheduled successfully, it is typically because iDRAC access is blocked to the Internet. This blockage prevents the firmware download task from completing successfully.

The update process involves several steps, and here's how the firewall setting can impact it:

Download the Updates to the Appliance: The updates are downloaded from Dell's servers or a local share. If this step fails, it could be due to a network or firewall issue1.

Mount SMBv2 Share to the iDRAC: This step uses ports 137, 138, 139, and 445. If iDRAC cannot access these ports on the Internet due to a firewall block, the update cannot proceed1.

Copy the firmware update to the iDRAC/CMC: If this step fails, it could be due to network issues, including firewall settings that block iDRAC's Internet access1.

The error that typically indicates a failure in this process is RED016: Unable to Mount Remote Share, which would occur if the iDRAC cannot access the necessary network resources due to a firewall blockage1. Therefore, ensuring that iDRAC has proper Internet access is crucial for the out-of-band update process to succeed.
