To expand on the original question, we have a network link between 2 sites that can't handle the default MTU size as defined on the Ethernet cards on the HMC console (it's a z9).
We have a few options available to us to resolve this, and, as some have so helpfully pointed out, one of those is to get the network configuration changed to allow the MTU size. While our network colleagues are investigating the impact to live services of that change, we were just wondering if any one had altered the MTU on a z9 HMC Ethernet card? Or, less specifically, has anyone logged into native linux on their z9? We believe we could alter this value with an IFCONIG command. Apparently it is possible but we are struggling to get hold of the default user ID and password. (If anyone knows them it’d be greatly appreciated if they’d email me off list!) We may very well end up needing to make the change to the network to resolve this 'challenge' but personally i would rather have as many options open to us as possible and would only put our clients connectivity at risk only as a last resort (if at all!).
