ds4700 failed logical drive
客户环境是ds4700+4 exp810. 因为其中一台exp810异常掉电，关闭所有存储电源后按照正常步骤重新加电（先扩展柜后主柜）。现在出现failed logical drive报错，但是硬盘都正常。

Failed Logical Drive - Drive Failure
Storage Subsystem: hlcorp
Array: sapdb
RAID level: 1
Affected logical drives:
Standard: heartdb, sapdev_bak, test_D23, testdb1, sapdb3, testdb2, aphp01_D21, aphp02_D22, sap_fs01, sap_fs02
FlashCopy: aphp01_D23, sapdb1, sapdb2
Status: Failed - incomplete array
What Caused the Problem?
One or more drives in the array have failed, causing the associated logical drives to fail. 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
If the logical drive is marked failed because you replaced the wrong drive during a degraded logical drive recovery procedure, you have not lost data. To return the logical drive to the degraded state, reinsert the drive.
You may be able to recover data from a failed logical drive. Whether or not this is possible depends on how the failure occurred. You can use this procedure to restore data in two ways: Contacting your technical support representative to attempt a data recovery or restoring data from backup media.
All I/O to the affected logical drives will fail.
To the operating system (OS), a failed logical drive is exactly the same as a failed non-RAID drive. Refer to the operating system documentation for any special requirements concerning failed drives and perform them where necessary.
Make sure the replacement drives have a capacity equal to or greater than the failed drives you will remove in the following steps.
You can replace the failed drives while other logical drive groups in the storage subsystem 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
It may be possible to recover data from the failed logical drives. If you wish to attempt a data recovery, you must contact your technical support representative. Do NOT perform steps 2 - 8. Performing any recovery actions before contacting your technical support representative could jeopardize any chance of recovering data. If you prefer to recover from an existing backup or you have mistakenly removed the wrong drive while performing a degraded logical drive recovery procedure, go to step 2.
2
If you have mistakenly removed the wrong drive while performing a degraded logical drive recovery procedure, you can return the logical drive back to the degraded state by replacing the drive you removed. After the logical drives return to the degraded state, select Recheck and perform the recovery procedure listed for a degraded logical drive. You are finished with this procedure.

There are several different types of logical drives that can exist in an array. Use the Recovery Guru details area to determine the affected array. Then, find the array in the Logical View of the Subsystem Management Window (AMW). Use the information provided by the AMW to determine the types of logical drives on the affected array. Step through every entry in the following table and perform all procedures associated with the logical drive type combination for the affected array.
