After reviewing the reports that were shared through the FTP, we confirm that the issue is not within the server. It could on the MSA port or path connected to Node A.
If this is an FC connectivity, schedule a downtime & reseat the SFP module & the cable that is connected to Node A & the respective controller on the MSA.
If this is a SAS based MSA, reseat the cables between Node A to the MSA
Monitor to check if the same events are logged again, if yes, need to validate the hard drives installed in the MSA for any faults.
Thank you.
