This solution is only available to members.

this looks quite like a zoning problem.
Are you running NPIV adapters? If so, please be aware that you must use WWN zoning on your new switch.
Port zoning will not work, because an NPIV adapter carries several WWNs, so just zoning the port is not enough.
Also please note that the switch port(s) must be made "NPIV" aware during switch setup.
The running nodes might use dedicated adapters or might be connected over a working VIOS.
