关于存储Hot Spare in Use的问题

关于存储Hot Spare in Use的问题，日志如下！

DS4700 其实按照日志可以看出步骤了，但是看红色的部分已经变成ＮＯ了！（Service action (removal) allowed: No），之前是ＹＥＳ，给我同事拔了出来，又插进去，就变成了ＮＯ了，现在都不太敢去换硬盘了！各位大神，帮助看看罗！谢了！！！

Logical Drive - Hot Spare in UseWhat 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 NotesWhen 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	Select Recheck to rerun the Recovery Guru to ensure that the failure has been fixed. If the failure appears again, contact your technical support representative.
