QwikContext

After upgrading pysnmp to 6.2.4, Ansible playbook using the dellemc.openmanage.idrac_system_info module fails with an error

[aaron-goulet-servicenow]

I've been able to confirm this issue as well. I have added an explicit pysnmp==6.1.3 directive to my project's requirements.txt as a workaround, but a permanent fix would be greatly appreciated!

[aaron-goulet-servicenow]

I'd also posit that the urgency of this problem is high, as this will affect anyone that is attempting to use the dellemc.openmanage Ansible collection, which ships as part of the main ansible package, out-of-the-box.

[anupamaloke]

@MallocArray, @aaron-goulet-servicenow, we are on it and will keep you updated on the release with the fix. Meanwhile, please continue to use the workaround as suggested by @aaron-goulet-servicenow. Thank you for your patience.

I found that updating omdrivers/iDRAC.py with from pysnmp.smi.rfc1902 import ObjectIdentity fixed the issue
