Have a major issue seeing an existing iscsi san from a pair of ESX 4 hosts.
When I first set these up I had a fair bit of difficulty in getting it to connect but eventualy I did.
Now I have (though I should have done before, doh) enabled Jumbo frames using the advice i this article;
I have also enabled jumbo frames on the SAN an HP MSA2312i.
The switches are 3Com Baseline Switch 2928 unit which support jumbo frames.
OK, I have this additional issue with particular Broadcom nics in use in this installation that VMWARE are aware of;
I have done as they have said and now the HBAs once again discover the iscsi SAN.
BUT try as I might I cannot rediscover the storage. I have rebooted and no change. I can vmkping the SAN addresses.
Some searching around has led me to a troubleshooting page;
My big concern here is that I don't have a /etc/vmkiscsi.conf file! Could this be my issue?
This is a pretty bad situation as VMs are down and I need it to be up (obviously)
Anyone got any clue?
