Recover a Failed Drive - CA6300

Applies to CA6300 appliance

Recover a physical drive by using the Disk Utilities option in the RAID Configuration Utility to verify disk media for errors and attempt recovery of bad sectors. Attempt recovery of a physical drive when a RAID array experiences any of the following conditions:

• Degraded state
• Stripe Failure
• SCSI errors reported by the operating system

Estimated time to recover a failed drive: 2-3 hours per drive

After attempting disk recovery, rebuild the array. If this is not successful, contact CA Support to request a disk drive replacement.

Important: In the CA Multi-Port Monitor web interface, use the RAID section of the System Status page to verify the logical array number of the failed disk. It can take up to two hours to verify a physical drive.

Follow these steps:

1. Restart the appliance.
2. Press Ctrl+A within 30 seconds to access the RAID Configuration Utilities menu.

   If necessary, restart the appliance again and press Ctrl+A.

   After the BIOS scan completes, select the Disk Utilities option in the RAID Configuration Utility.

   

3. Select the disk that you want to recover and press Enter. For the:
   • System Array:

     CN1 :Dev 00 corresponds to Disk 1

     CN1 :Dev 01 corresponds to Disk 2

   • Data Array:

     Box00:Slot00 corresponds to Disk 0

     Box00:Slot01 corresponds to Disk 1

     Box00:Slot02 corresponds to Disk 2

     Box00:Slot03 corresponds to Disk 3

     Box00:Slot04 corresponds to Disk 4

     Box00:Slot05 corresponds to Disk 5

     Box00:Slot06 corresponds to Disk 6

     Box00:Slot07 corresponds to Disk 7

     Box00:Slot08 corresponds to Disk 8

     Box00:Slot09 corresponds to Disk 9

     Box00:Slot10 corresponds to Disk 10

     Box00:Slot11 corresponds to Disk 11

     Box00:Slot12 corresponds to Disk 12

     Box00:Slot13 corresponds to Disk 13

     Box00:Slot14 corresponds to Disk 14

     Box00:Slot15 corresponds to Disk 15

     Note that for the Data Array, disks 0 through 15 correspond to drives 0 through 15 on the front of the Multi-Port Monitor chassis.

   In the following example, the highlighted disk corresponds to Data array Disk1.

   

4. Select Verify Disk Media and press Enter.

   

   It can take up to two hours to verify and recover a physical drive.

4. Choose the Disk Utilities option.
5. Select the disk that you want to recover and press Enter. For the:
   • System Array:

     CN0 :Dev 00 corresponds to Disk 1

     CN0 :Dev 01 corresponds to Disk 2

     CN0 :Dev 02 corresponds to Disk 3

     CN0 :Dev 03 corresponds to Disk 4

     Note that for the System Array, disks 1 through 4 correspond to the same drive numbers on the front of the Multi-Port Monitor chassis.

   • Data Array:

     CN0 :Dev 00 corresponds to Disk 1

     CN0 :Dev 01 corresponds to Disk 2

     CN0 :Dev 02 corresponds to Disk 3
