I created 4 VFs on SR-IOV and let OpenSM support virtualization, but currently all VFs’ port state are still down, so I tried to configure node GUID, port GUID and policy GUID. However, when I excuted command “echo 00:11:22:33:44:55:1:0 > /sys/class/infiniband/mlx5_0/device/sriov/0/node”, it failed. Then I tried to enter and edit this file by vim, it reported error log as follows.
Please ask what should I do next? Thank you very much!
