Hello, I suggest you to (re)post also on HPE Community (right section to post for ArubaOS-Switch based switches is here) so also HPE Community users can give you an help.
A sanitized configuration of your Aruba 2930M and also of your Server NIC's ports (Are you using Teaming? if so...which type?) and OS it is running on...would help to better diagnose if there is a real issue and what it is.
