A drive is reporting internal errors that could cause the drive to fail. No more drives can fail in this array without losing data. If this drive fails before you follow these recovery steps, the logical drives in the array will fail and all data on the logical drives will be lost.
The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.
Caution: Risk of Data Loss. This
problem needs to be resolved immediately. Data loss will occur if the indicated drive fails before you follow these recovery steps.
Caution: Electrostatic discharge can damage sensitive components. Always use proper antistatic protection when handling components. Touching the components without using a proper ground may damage the equipment.
If the current status/RAID level of the logical drives is... | Then go to... |
Optimal RAID 0 | Recovering RAID 0 |
Degraded RAID 1, 3, 5, or 6 | Recovering Degraded Logical Drives |
RAID 1, 3, 5, or 6 with a hot spare drive currently being reconstructed | Recovering with a Reconstructing Hot Spare |
Use the following procedure if the affected logical drives are RAID 0.
1 | Stop all I/O to the affected logical drives. |
2 | Back up all data on the affected logical drives. (Step 5 will destroy all data on the affected logical drives.)
Note: To the operating system (OS), a failed logical drive is exactly the same as a failed non-RAID drive. Refer to the OS documentation for any special requirements concerning failed drives and perform them where necessary. |
3 | If any of the affected logical drives are also source or target logical drives in a copy operation that is either Pending or In Progress, you must stop the copy operation before continuing.
Go to the Copy Manager by selecting Logical Drive >> Copy >> Copy Manager, then highlight each copy pair that contains an affected logical drive and select Copy >> Stop. |
4 | If you have flashcopy logical drives associated with the affected logical drives, these flashcopy logical drives will no longer be valid once you fail the drive in
step 5.
Perform any necessary operations (such as backup) on the flashcopy logical drives and then delete them. |
5 | ![]() Highlight the affected drive in the Physical View of the Subsystem Management Window and select Advanced >> Recovery >> Fail Drive. The affected logical drives become Failed |
6 | Remove the failed drive (its fault indicator light should be on). |
7 | Wait 30 seconds, then insert the new drive. Its fault indicator light may be lit for a short time (one minute or less).
Note: Wait until the new drive is ready (its fault indicator light must be off) before attempting to initialize the logical drives in step 8. |
8 | Highlight the array associated with the replaced drive in the Logical View of the Subsystem Management Window and select Advanced >> Recovery >> Initialize >> Array.
Note: Make sure you save this procedure by selecting Save As because once you perform step 9 and the failure is fixed, you will not be able to access the information in steps 10 and 11 from the Recovery Guru. |
9 | 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, otherwise, go to step 10. |
10 | Add the affected logical drives back to the operating system. You may need to reboot the system to see the re-initialized logical drives.
Note: Do not start I/O to these logical drives until after you restore from backup. |
11 | Restore the data for the affected logical drives from backup. |
12 | If desired, create any flashcopies that you deleted in step 4. |
13 | If desired, re-create any copies you stopped by highlighting the copy pairs in the Copy Manager and selecting Copy >> Re-Copy. |
Use the following procedure if the affected logical drives are degraded RAID 1, 3, 5, or 6. You will need two replacement drives for this procedure.
Caution: Risk of Data Loss. An Impending Drive Failure means that the affected drive is likely to fail. If it fails while you are replacing the drive that has already failed on this array (see steps 3 and 4 below), you will lose all data on the affected logical drives.
1 | Although it is not required, you should stop all I/O to the affected logical drives to reduce the possibility of data loss. |
2 | Although it is not required, you should back up all data on the affected logical drives. |
3 | Remove the failed drive. The fault indicator light for the drive should be on.
Note: The Service Action Allowed status in the Details area is always NO for this problem because the component is not yet failed. In this situation, it is acceptable to remove the component even though the Service Action Allowed is NO. |
4 | Wait 30 seconds, then insert the
new drive.
|
5 | Wait until all affected logical drives have returned to an Optimal status. Resume I/O to the affected logical drives, if you stopped it in step 1. |
6 | Highlight the Impending Drive Failure drive in the Physical View of the Subsystem Management Window and select Advanced >> Recovery >> Fail Drive. The logical drives in the array return to a Degraded state. |
7 | Remove the failed drive (its fault indicator light should be on).
Note: The Service Action Allowed status in the Details area is always NO for this problem because the component is not yet failed. In this situation, it is acceptable to remove the component even though the Service Action Allowed is NO. |
8 | Wait 30 seconds, then insert the new drive. |
9 | 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. |
Use the following procedure if all of the following conditions apply:
Caution: Risk of Data Loss. An Impending Drive Failure means that the affected drive is likely to fail. If it fails while the hot spare is reconstructing, you will lose all data on the affected logical drives. For this reason, you should stop all I/O to the affected logical drives and back up all data on the affected logical drives before replacing the drives./p>
1 | Although it is not required, you should stop all I/O to the affected logical drives to reduce the possibility of data loss. |
2 | Although it is not required, you should back up all data on the affected logical drives. |
3 | Wait for the hot spare drive to finish reconstructing.

4 | 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. |
