Hi, The meaning of 1 message is some fram transmit error encountered by hardware and the I/O request is aborted by firmware because of the error, The second message indicates, some I/O got timed out and the SML tries to abort the request and the firmware completes the I/O before aborting that. Hence returns IO executed message and the driver completes the abort as success. Suspecting some bad hardware in the topology(cables?)
