6027-4311 [E] Unable to find an operational RDMA port on virtual fabric number fabricNumber for GPU Direct Storage I/O.

Explanation

All RDMA ports on the given virtual fabric are in down state. At least one operational port is required to perform GPU Direct Storage (GDS) I/O. The I/O operation will be retried in compatibility mode resulting in degraded performance.

Check all RDMA adapter ports and the RDMA fabric for errors.
