Hi everyone
Recently our SAP on-prem server (we dont use it anymore, we moved to the cloud but still have the old on prem hardware that we keep for archives/audit purposes) stopped working.
There are 4 physical hosts each with their own VMs running. One of the physical hosts, as well as its VM can be pinged and has general connectivity, including internet access. On this one the ethernet link lights (there are 4 ports on each machine) are not flashing,there is only the solid green light telling its up and running
The other 3 that cannot be communicated with have the status light normal solid, but the traffic lights flashing like crazy. These (the physical machines as well as their running VMs) are not able to ping their own gateway - destination host unreachable error. The one working physical host/VM mentioned above is on this same VLAN with the same gateway and can ping it successfully.
The switch they are connected to is also lit up like a Christmas tree.
I dont think it is a broadcast storm issue as STP is enabled but not needed anyway as our switches are not inter connected, just go back to the main core switch.
Also, for all of these servers (Dells) the iDRAC management web interface works fine. Tried rebooting all of them using that, and the diagnostic says the systems are healthy.
Anyone have any idea what could be the issue here? I'm pretty certain its a networking issue but not sure what exactly
Thanks everyone!
