An Oceanstor V3 system "alert" shows a message: "SPF [0] LOW Rx power alarm because Low Rx pow ALM of SFP0 is deleted/deflected. "The cause of the malfunction is:
In the OceanStor VIS6600T dual-redundant switch network environment, using OceanStor Toolkit inspection found that "multi-path state detection "does not pass the inspection report. It is found that there are two routes in the 4 paths of the VIS6600T device's 0 node to each LUN of the array. The path status is disabled. According to the analysis, the switch port connected to port 0 of port A0 of node 0 on node 0 of the VIS6600T is visible on the optical switch. The received optical power is much lower than the rated power of the optical module.
What actions should be taken to fix this?
