I have a question regarding FCoE we have FCoE local in the datacenters with cdot clusters serving lun's this works great. But now we need to access lun's on an other cDot cluster on a remote site we've got FCoE over the sites in place server sees the LUN's but when putting a load on it we get FCPIO_DATA_CNT_MISMATCH.
The local config that works is AFF 8040 -> Nexus 5000 -> UCS
We've link between host and storage and the storage is readable writeable. But it's not stable even with a small load paths fail and come back everytime the higher the load we put on the more we see the links fail and come back.
An late update on the this issue. We finally got an statement from cisco that the current configuration as we have isn't supported for the distance we have. So we need old school FC swicthes between our datacenters.
