电力VC降级经过程
10月28号接到电力VC降级的case，去之前查阅了两种降级方式，第一种是HPSUM，另一个是vcsu方式，到达现场后发现HPSUM这种方式能把OA和其他的firmware可以降下来，但是VC模块的版本降级不成功，就改用VCSU方式降级，降级方式如下：
vcsu -a update -i 192.168.0.1 -u Administrator -p HWGYDAC7 -vcu Administrator -vcp Z66BT2RX -l D:\vcfwall410.bin
OAIP OA用户 OA密码 VC用户 VC密码 fw路径
第一台降级成功后第二台用同样方式进行降级时，一直报错找不到bay设备，在OA下敲入connect bay 命令时报错如下：

但是第一天连接MP时也不成功，然后进行bay的掉电试MP卡重置，还是报错，由于客户下班原因就准备将报错日志拷下来进行再降级，今天到达现场进行MP掉电重置时发现可以连接MP成功，就按照RC的解决办法进行SSH的enabled操作，操作完成后在OA里进行connect bay操作可以成功，就按照VCSU方法进行降级，当降级进行到第二步时报错出现：

再次请求RC支持给的方案是将VC模块重置，重置后发现还是不行，报错一样，在各种方法试遍之后，我将设备的HP VC 8Gb 20-Port FC Module模块从2槽位移到3槽位进行降级操作，降级成功，成功将两台设备的VC模块降级到4.1。
