We have a Vmware 6.0 cluster and using Netapp FAS2240-4 (8.23) for storage.
Each esxi host is using hardware iscsi has vmhba1 and vmhba2 configured with an ip address each
on an esxi host if I check the MTU for the iscsi adapter I see:
[root@dev-svr-03:~] esxcfg-hwiscsi -l vmhba1
DHCP Configuration Disabled
ARP Redirection Disabled
MTU Size = 8342
This seems to be the maximum the card we are using can support as mentioned here:MTU question
Our switch is set to 9198 and the netapp is set to 9000.
Should they all be set to 8342?
Also how can I test the mtu settings. I've seen you can vmkping but how can I do that from vmhba1 as it's doesn't have a network interface but is assigned an ip address?
