进到MS上用哪个听诊器的工具收到如下信息Details
Storage Subsystem: nmlf-DS4700
Degraded drive channels: 1, 2

Degraded Drive Channel What Caused the Problem?
A drive channel status was set to Degraded because of excessive I/O errors or because a technical support representative advised the array's administrator to manually set the drive channel status for diagnostic or other support reasons. It is important to correct this failure as soon as possible. The drives are still operational, but a level of path redundancy has been lost. If the other channel to the drives fails, then the drives themselves could be failed. The Recovery Guru Details area provides specific information you will need as you follow the recovery steps. Important Notes You must contact your technical support representative to correct this failure. DO NOT attempt to fix this problem yourself.If a Loss Of Path Redundancy failure is also being reported in the Summary area of the Recovery Guru, you MUST fix this failure first; otherwise, you could lose both paths to the drives.DO NOT manually set the drive channel to Optimal until you have consulted with your technical support representative.

这个是不是B控的电池坏了？如果是B控的电池坏了，会不会影响数据的读写？

这个问题该怎么分析解决，确定一下错误，望高手们指点一下  不胜感激
