Hello,
We are migrating our infrastructure to ESX4.We have multiple servers connected via SAN to an IBM DS8300 virtualized via the IBM SVC. When we created the zonning for hosts esx3.5 and esx4 (both Server Blade 680c) to share some of the LUN's we lost the connection and began to have more communication problems with storage.
The path to the SVC is set to MRU on ESX hosts. Fixed know that would be correct in this case.
Some errors are in vmkernel log :

Anyone see this behaviour before ?
Thanks
