Question #69

In the OceanStor VIS6600T dual-redundant switch network environment, using OceanStor Toolkitinspection found that "multi-path state detection "does not pass the inspection report. It is foundthat there are two routes in the 4 paths of the VIS6600T device's 0 node to each LUN of the array. Thepath status is disabled. According to the analysis, the switch port connected to port 0 of port A0 ofnode 0 on node 0 of the VIS6600T is visible on the optical switch. The received optical power is muchlower than the rated power of the optical module.What actions should be taken to fix this?

A. eplacing the optical module of port 0 in slot A0 of node 0

B. eplacing the light of the P0 port in the A0 slot of 0 node

C. eplacing the optical module of the port connected to port 0 of the corresponding 0-node A0 slot on the switch
