  About fault diagnosis on the capacity of hard disk box, which are wrong?

  A. S5000V1Rs and its subsequent version can realize the back-end cascade self-adaption, therefore need to power up on the storage system again, can adjust the speed of cascade links.
  B. If appear speed rate of dial-up are inconformity between expansion box and host box, can through the following method to adjust: 1, login MML through fc gps to check the original hard disk box rate in loop 2, dial switch in new box and loop line are in agreement 3, power up and down on expansion box, check whether the capacity of hard disk box is normal access.
  C. After expansion failure, need to check the expansion network are correct connected, and then check HUB and cable on expansion link are normal
  D. The reason of expansion failure have nothing to do with control box system and the order of power up on new extension box.So when power up on system, can automatically adjust the order of cascade link between the controller box and hard disk box
  D. The reason of expansion failure have nothing to do with control box system and the order of power up on new extension box.So when power up on system, can automatically adjust the order of cascade link between the controller box and hard disk box
