One or more drives have failed in an array causing the modification operation (for example, changing RAID level or adding capacity) to be suspended. The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.
Caution
Electrostatic discharge can damage sensitive components. Use a grounding wrist strap or other anti-static precautions before removing or handling components.

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 - 10. 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, go to step 2. |

Note: If you have FlashCopy logical drives associated with the affected array, these FlashCopy logical drives will no longer be valid. Delete all FlashCopy logical drives associated with the affected array. |

Remove all failed drives associated with this array (the fault indicator lights on the failed drives should be lit). To determine the associated drives, select one of the affected logical drives, listed in the Recovery Guru Details area, in the Logical View of the Subsystem Management Window. Each associated drive will have an association dot underneath it. |

Wait 30 seconds, then insert the new drives. The fault indicator light on the replaced drives may be lit for a short time (one minute or less). |

Perform the following steps on the replaced drives to transition the logical drive to a degraded state:
Note: To monitor the progress of the modification or reconstruction operations, select the 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. |

Select the array in the Logical View of the Subsystem Management Window; then, select Array>>Initialize. Result: The logical drives in the array are initialized, one at a time. When initialization starts on a logical drive, the icon changes to Operation in Progress Note: To monitor progress or change the rate of the initialization, select the 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. 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 9 and 10 from the Recovery Guru. |

Select Recheck to rerun the Recovery Guru to ensure that the failure has been fixed. |

If desired, create any FlashCopys that you deleted in Step 2. |

Add the re-initialized logical drives to the operating system. You may need to reboot the system to see the logical drives. Note: Do not start I/O to these logical drives until after you restore from backup. |

Restore the data for the re-initialized logical drives from backup media. |
