请教DS4700的故障解决
我有更好的答案
先观察系统板卡的插头、插座是否歪斜.先检查机外部件，一般应遵循以下几个原则：
1，电阻、电容引脚是否相碰。同时也要监听电源风扇、软/硬盘电机或寻道机构、显示器变压器等设备的工作声音是否正常，表面是否烧焦，芯片表面是否开裂，再检查机内部件
对主机或显示器不亮灯的故障，应先检查机外的开关、保险，主板上的铜箔是否烧断；还要查看是否有异物掉进主板的元器件之间造成短路，也可以看看板上是否有烧焦变色的地方、印刷电路板上的走线（铜箔）是否断裂等等。
另外、插座有无断路、短路等，确认机外部件正常后再打开机箱或显示器进行检查，注意辨闻主机、板卡中是否有烧焦的气味，便于发现故障和确定短路所在地。打开机箱后。另外，系统发生短路故障时常常伴随着异常声响，监听可以及时发现一些事故隐患和帮助在事故发生时及时采取措施电脑常见硬件故障检修的原则
电脑出现故障，通常有一些蛛丝马迹可寻。进行故障检查诊断

回答问题，赢新手礼包ds4700处理黄灯故障过程一例
解决问题前，先提下存储工具recovery guru
The Recovery Guru is a component of the Subsystem Management window (SMW) that diagnoses problems and recommends recovery procedures to fix the problems
恢复Guru是子系统管理窗口的组件，它能够诊断问题并推荐恢复步骤以用来修复该错误。
一下图为ds4700 critical log 截图
描述信心：温度超标&&&&& Description： nominal temeratre&exceeded
事件种类： 失效&&&&&&&& event category: failure
组件类型：温度传感器&&& component type: temperature sensor
从上面信息大致可以判断出：由于温度传感器检测到其周围温度过高而亮起了黄灯。
二 ds4700 recovery guru 截图如下
What caused the problem ？什么导致这个问题呢？ 图中提示了如下三种可能
The nominal temperature of the enclosure has been exceed. Ether a fan has failed, an obstruction is blocking the air flow to or from the enclosure, or . The recovery guru details area provides specific information you will need as you follow the recovery steps.
1&&&&&&&& a fan has failed&&&& 风扇坏了
2&&&&&&&& an obstruction is blocking the air flow to or from the enclosure&障碍物堵塞了盘柜壳子的通风口
3&&&&&&&& &the temperature of the root is too high&房间温度太高了
三 recovery guru 给出的恢复步骤如下图
上图说了大概三个意思
1如果有风扇失效的报告，依照相关步骤解决这个问题
2 如果没有风扇失效的报告，移除任何阻挡通风口的障碍物，如果没障碍物，那就是房间冷却系统的问题。
3处理完相关问题后，重新运行recovery guru检查是否有相关问题
四 开始处理问题
1 检查存储的风扇有没有问题下图为虚拟存储截图真实存储风扇状态也如下图所示。
2 既然风扇没有失效，查看磁盘阵列通风口，也没有被大的障碍物挡住，不排除灰尘问题。
3 关于房间冷却系统，进去后感觉温度还挺低，如果温度高，那不仅仅是存储，估计所有小鸡都会亮起黄灯，所以这个可以排除，不去考虑。
4 等结业后，拆分ds4700 用吹风机吹，瞬间楼道内全是浓烈的灰尘&&&除尘完毕，组装好存储，通电，远程登录，点击recovery guru 提示故障排除。
五 总结：通过存储管理软件访问存储，b控制器的温度传感器检测周围温度过高，拆分存储的时候，果然b控制器温度明显比a控制器温度高。看来阻挡通风口的不光是障碍物还有灰尘。

回答问题，赢新手礼包&#xe6b9;请教DS4700的故障解决客户一个DS4700最近报错如下：报错一：Degraded Drive Channel [size=+-1]Storage Subsystem:
Unnamed&&Degraded drive channels:
1What 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 fi 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.Recovery Steps 1 Check the Summary area of the Recovery Guru to see if there is a Loss Of Path Redundancy failure being reported. If this failure is being reported, fix it first before going to step 2. 2 Select the Advanced >> Troubleshooting >> Support Data >> Collect menu option from the Subsystem Management Window (AMW), and take the appropriate steps to save the support data to a .zip file. 3 If the reason for the degraded drive channel in the Recovery Guru Details area is "Manually set", go to step 5. 4 Contact your technical support representative and indicate that a "Degraded Drive Channel" problem is being reported. Send your representative the file you saved in step 2 and wait for further instruction. 5 If after consultation with a technical support representative or the person who manually set the drive channel status to Degraded, you believe the drive channel is operating properly, you may choose to manually set the drive channel status to Optimal. Select the Advanced >> Troubleshooting >> Drive Channels menu option, then select the degraded drive channel and click the Set Optimal button. Note: The drive channel status may automatically be reset to Degraded if the controller again determines that the channel is not operating properly. 6 Click the Recheck button to rerun the Recovery Guru. The failure should no longer appear in the Summary area. If the failure appears again, contact your technical support representative. 报错二：Logical Drive - Hot Spare in Use [size=+-1]Storage Subsystem:

2, 3, 4, 5, 6, 7, 1& &&&RAID level:
5& &&&Status:
OptimalWhat Caused the Problem? One or more drives have failed, and hot spare drives have automatically taken over for the failed drives. The data on the logical drives is still accessible. The Recovery Guru Details area provides specific information you will need as you follow the recovery steps. &&Caution: Possible loss of data accessibility. Do not remove a component when either (1) the Service action (removal) allowed (SAA) field in the Details area of this recovery procedure is NO (), or (2) the SAA LED on the affected component is OFF (note that some products do not have SAA LEDs). Removing a component while its SAA LED is OFF may result in temporary loss of access to your data. Refer to the following Important Notes for more detail. &&Caution: Electrostatic discharge can damage sensitive components. Always use proper antistatic protection when handling components. Touching components without using a proper ground may damage the equipment. Important Notes When a hot spare takes over for a failed drive, data from the failed drive is reconstructed on the hot spare. When you replace the failed drive, data is copied back from the hot spare to the new drive and the hot spare returns to Standby. You can replace the failed drive before reconstruction is completed on the hot spare. However, the copyback to the new drive will not occur until the reconstruction has completed.Look at the logical drive icons for the affected logical drives in the Logical View of the Subsystem Management Window. If any logical drives display an Operation in Progress icon , reconstruction is still taking place on the hot spare. If all logical drive icons are Optimal , reconstruction is completed.Depending on how many hot spares you have created in the storage subsystem, a logical drive could remain Optimal and still have multiple failed drives (each one being covered by a hot spare).Make sure the replacement drives have a capacity equal to or greater than the failed drives.You can replace the failed drives while the affected logical drives are receiving I/O.Service Action Allowed Important Information:The Service action (removal) allowed field in the Details area indicates whether or not you can safely remove the component. If the SAA field is NO (), then the affected component must remain in place until you service another component first.The Service action LED on Component field in the Details area indicates whether or not a physical SAA LED is present on the hardware component. This field does NOT indicate whether the LED is ON or OFF (that indication is provided by the Service action (removal) allowed field).If a component does not have an SAA LED, then it is OK to remove the component when its fault LED is lit and the Service action (removal) allowed field = YES () in the Details area.The Service action (removal) allowed field shown in the Details area and the physical SAA LED on the hardware component (if supported) MUST match before you remove the affected component. In rare cases (such as multiple problems), the status of the LED and the SAA field may not match. If there is a mismatch, then you should NOT remove the component until these indications match.Recovery Steps 1 Check the Details area to identify the failed drive. 2 Remove the drive (its fault indicator light should be on). 3 Wait 30 seconds, then insert the new drive. Its fault indicator light may be lit for a short time (one minute or less). Result: The affected logical drives in the Logical View of the Subsystem Management Window change to an Operation in Progress icon
as the reconstruction/copyback operations take place. When reconstruction/copyback is completed, the logical drives return to Optimal , and the hot spare drive returns to Standby. To monitor reconstruction progress on the affected logical drives select the affected logical drive, then select Logical Drive >> Properties. Note that once the operation in progress has completed, the progress bar is no longer displayed in the properties dialog. 4 Repeat steps 1 through 3 for each failed drive. 5 Click the Recheck button to rerun the Recovery Guru. The failure should no longer appear in the Summary area. If the failure appears again, contact your technical support representative. 报错三：Individual Drive - Degraded Path [size=+-1]Storage Subsystem:

(85, 5)What Caused the Problem? The specified drive channel is experiencing intermittent errors along the path to a single or several drives. 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 it yourself.If a "Loss of Path Redundancy" problem is also being reported in the Summary area of the Recovery Guru, you MUST fi otherwise, you could lose both paths to the drives.DO NOT click the Recheck button until you have consulted with your technical support representative.Correct this failure as soon as possible. The drives are still operational, but a level of path redundancy may be lost. If the other channel to any of these affected drives fails, the drives themselves could be failed.Recovery Steps 1 Check the Summary area of the Recovery Guru to see if there are any additional problems being reported. If there are other problems reported, fix those problems first before going to step 2. 2 Select the Advanced >> Troubleshooting >> Support Data >> Collect menu option from the Subsystem Management Window (AMW), and take the appropriate steps to save the support data to a .zip file. 3 Contact your technical support representative and indicate that a "Individual Drive - Degraded Path" problem is being reported. Send your representative the file you saved in step 2. 截图：请问，问题一是不是因为磁盘坏了引起的，换这个磁盘是不是就是把坏磁盘拔了，好磁盘插上就行。然后如果磁盘故障恢复了，问题一会不会自动消失？请高手帮忙解答。回答邀答26回答&
