What Caused the Problem?
A drive is reporting internal errors that could cause the drive to fail. 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
Resolve this problem immediately, because data will be lost if the indicated drive fails before you follow these recovery steps.
Caution
Electrostatic discharge can damage sensitive components. Use a grounding wrist strap or other anti-static precautions before removing or handling components.
Important Notes
If the current status/RAID level of the logical drives is... | Then go to... |
Optimal RAID 0 | Recovering RAID 0 |
Degraded RAID 1, 3, or 5 | Recovering Degraded Logical Drives |
RAID 1, 3, or 5 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.
Recovery Steps
1 | Stop all I/O to the affected logical drives. |
2 | The recovery procedure will destroy all data currently on the affected logical drives. Therefore, back up 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 | Highlight the affected drive in the Physical View of the Subsystem Management Window and select Drive>>Fail. The affected logical drives become Failed ![]() |
4 | Remove the failed drive (its fault indicator light should be on). |
5 | Wait 30 seconds, then insert the new drive. Its fault indicator light may come on 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 6. |
6 | Highlight the array associated with the replaced drive in the Logical View of the Subsystem Management Window and select Array>>Initialize.
Note: Make sure you save this procedure by selecting Save As because once you perform step 7 and the failure is fixed, you will not be able to access the information in steps 8 and 9 from the Recovery Guru. |
7 | Select Recheck to rerun the Recovery Guru to ensure that the failure has been fixed. |
8 | 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. |
9 | Restore the data for the affected logical drives from backup. |
Use the following procedure if the affected logical drives are degraded RAID 1, 3, or 5. You will need two replacement drives for this procedure.
Caution
An Impending Drive Failure means that the affected drive is likely to fail. If it fails while you are replacing the failed drive (steps 3 and 4 below), you will lose all data on the affected logical drives.
Recovery Steps
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 drive currently failed, not the drive with the Impending Drive Failure). The fault indicator light for the drive should be on. |
4 | Wait 30 seconds, then insert the new drive. Its fault indicator light may come on for a short time (one minute or less).
|
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 Drive>>Fail. The logical drives in the array return to a Degraded state. |
7 | Remove the failed drive (its fault indicator light should be on). |
8 | Wait 30 seconds, then insert the new drive. Its fault indicator light may come on for a short time (one minute or less). |
9 | Select Recheck to rerun the Recovery Guru to ensure that the failure has been fixed. |
Use the following procedure if all of the following conditions apply:
Caution
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.
Recovery Steps
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 | Select Recheck to rerun the Recovery Guru to ensure that the failure has been fixed. |
