Server is showing 'SCSI error: return code = 0x06050000' in the logs and presenting disk issues

Issue

• One of our clustered servers started having disk issues.
• When checking the logs, we found the following messages constantly repeated themselves:

• As a consequence, the server stopped responding and was eventually fenced by the other node.
