Hello all,
Same issue we are facing. When high I/O load started, one host is losting other host, host isolation is occuring. We checked everyting, HPE/VMware side, all is ok. Now we found a lot of discard at the port of Cisco Nexus 5548 switches in case of failure. We opened a ticket to Cisco, we are waiting their answer. We are searching an answer of what it is the root cause of discards on the network ports.
