CMMVC1174E The command failed because NVMeTCP/RDMA host creation is not supported over ports with MTU
greater than 1500.
Explanation
FlashSystem NVMeTCP/RDMA protocols do not work with Ethernet ports that have MTU
greater than 1500. Creating a new NVMeTCP/RDMA host or changing an existing NVMeTCP/RDMA host fails
if the portset has Ethernet ports with MTU greater than 1500.
User response
Use FlashSystem NVMeTCP/RDMA protocols only with Ethernet ports that have MTU of
1500.
