Detect a Missing Drive - CA6300

Applies to CA6300 appliance

When you start the appliance, if the RAID controller cannot detect a drive, the BIOS requests you to accept the configuration changes to the array and initiate a rebuild with fewer drives. We recommend rebuilding the array before attempting to detect a missing drive.

Use the RAID Configuration Utility to list the drives currently seen by the RAID controller:

• The System Array has two drives
• The Data Array has sixteen drives

If the utility does not detect a drive, use the RAID Configuration Utility to rescan the drives in the array and verify their status. It is possible that a rescan will allow the RAID controller to detect the drive. If rescanning the drives currently seen by the RAID controller confirms that the physical drive is not available, replace the physical drive as soon as possible. Contact CA Support for assistance.

Note: The BIOS utilities lists the drives that are detected by a RAID controller, but it does not indicate the status of a particular drive, such as Failed or Rebuilding, within a logical array.

Follow these steps:

1. Restart the appliance.
2. If the terminal display indicates an array is in a Degraded state, press Ctrl+A within 30 seconds to access the RAID Configuration Utility menu.

   The appliance continues to operate in its Degraded state unless you press Ctrl+A within the 30-second window. If you miss this window, restart the appliance and press Ctrl+A.

3. Select Logical Device Configuration.

   

4. Select Manage Arrays from the Main Menu.

   

5. Select the OS or Data array and press Enter to display array properties.

   

6. The Array Properties lists each drive in the array. If a drive is not listed, select Rescan Drives from the Main Menu to force the BIOS to rescan the drives in the array and verify their status.

   

7. If a rescan successfully detects a missing drive, select the newly detected drive and choose Verify Disk Media.

   

8. If the rescan fails to detect a missing drive, the drive may need to be replaced. Contact CA Support for assistance.

When you start the appliance, if a RAID controller cannot detect a drive, the BIOS requests you to accept the configuration changes to the array and initiate a rebuild with fewer drives. We recommend rebuilding the array before attempting to detect a missing drive.

Use the Array Configuration Utility to list the drives currently seen by the RAID controller:

• The System Array on the Adaptec 5405 has four drives
• The Data Array on the Adaptec 52415 has twelve drives

If the utility does not detect a drive, use the Array Configuration Utility to rescan the drives in the array and verify their status. It is possible that a rescan will allow the RAID controller to detect the drive. If rescanning the drives currently seen by the RAID controller confirms that the physical drive is not available, replace the physical drive as soon as possible. Contact CA Support for assistance.

   The appliance continues to operate in a degraded state unless you press Ctrl+A within the 30-second window. If you miss this window, restart the appliance and press Ctrl+A.

3. After the BIOS scan completes, the Utilities menu for a controller can be reached by selecting #0 for the 5405 (System array) and #1 for the 51245 (Data array):

   

4. Choose the Array Configuration Utility option.

   

5. Select Manage Arrays from the Main Menu.

   The Array Properties lists each drive in the array. If a drive is not listed, select Rescan Drives from the Main Menu to force the BIOS to rescan the drives in the Array and verify their status.

   If a rescan successfully detects a missing drive:

   1. Exit the Array Configuration Utility.
   2. Enter Disk Utilities.
   3. Select the newly detected drive and choose Verify Disk Media.

   

6. If the rescan fails to detect a missing drive, the drive may need to be replaced. Contact CA Support for assistance.
