Hi there,
I am experiencing port timeouts on some of my drives in a storage pod with 45 drives, I assume this is because of PCI bandwidth contention/congestion caused by port multipliers.
However when I try to force the drives to SAT revision 1, only the first drive on the port multiplier is limited down and the rest remains at v2.
I have searched high and low but the results all have been unhelpful, google in this case wasn't my friend. Any hints on how to accomplish this for all drives would be much appreciated.
