We have 4 new DL360’s GEN10, and we’re having issues with the switch ARP table not following what the servers have going on, and we’re seeing it seems to be mostly on the 10GBC ports.

I’ve ran this up with HPE and Aruba(switch) and they’re pointing at the OS (ESXI 6.5) as being the issue.

We have ISCSI and its running on the second SFP+ port going into a separate switch with Nimble storage, thats working great. No issues i’m aware of.

The VM’s will randomly drop off, and i’m stuck moving them to 1GB ports, or VMotion to another server. The switch will show all 0’s for a mac, and not list a port, but have the IP in the arp table. This seems to be only happening on the VMS on the new environment, and they all came from a 6.0 version of vmware, and we migrated them over. We haven’t had as many problems on the 1GB ports, but a few other people involved have told me we have. This was running from Friday until this morning with no problems, and today at 8 am it died. We moved the servers onto the 1GB and vmotion to another host and seems to be fine. This randomly happens across all the hosts, and we’ve not found anything to be strange, and the ISCSI doesn’t skip a beat.

Suggestions?
