RAID array degradation detected since 7/8/2011 at 11:28
am (10 minutes). Please contact your technical support
representative to replace the drive. No data has been lost. =DETAILS BELOW= A drive has failed in array 1 at position 1; it is recommended that a replacement drive be inserted there. |
On a P-Series or Enterprise Appliance, the system status
indicator on the front panel will flash from white to blue when the system detects a RAID drive has failed.
The number of blue flashes indicates which drive needs replacing (e.g., two flashes means Drive 2 has
failed ( Image Modified).

Rebuild RAID Array
| Warning |
|---|
In order to decrease the time it takes to rebuild the RAID array, Disk Write Cache will automatically be enabled on a 3VR appliance when it enters the RAID rebuild state. It is critical that the appliance not lose power during the rebuilding process or else file system corruption and/or data loss could occur. 3VR recommends the use of a UPS (Uninterruptable Power Supply) to protect the appliance in the event of a power failure. |
After replacing the failed drive, use the following steps to initialize the RAID rebuild process:
3VR Software Version 6.0
|
|
|---|
- In the Manage Servers tab of System Manager, select the name of the appliance with the new RAID drive.
- Click RAID/Disk Settings.
- In the RAID/Disk Settings window, click Rebuild RAID Array. If the Rebuild RAID Array link is not present, see Appendix B: Troubleshooting.
- It will take about a minute to initialize the RAID rebuild.

5. Verify that the RAID Array Status field displays “Rebuilding”.
6. Launch 3VR OpCenter and verify that the appliance appears to be functioning properly.
If new events are not being generated, or if video does not play when an event card is selected, contact 3VR Technical Support for assistance.

| title | What Are Hot Spares? |
|---|
| See Appendix D to learn more about the hot spares
feature of the P-Series appliance. |
Within 10 minutes of initializing the rebuild: 7. The P-Series (or Enterprise Appliance) status indicator will
return to solid white, indicating normal operation.
8. The RAID/Disk Issue health alert will display the percentage remaining in the rebuild process.
9. This value will be updated every 10 minutes until the system has finished rebuilding the array, at which point the health alert will state “RAID array rebuild done”. | Note |
|---|
Note that the rebuild will be complete at this point, even if the Percentage Complete value displayed is not 100%. |

When an appliance with a hot spare installed detects the failure of one of the RAID array member disks, the appliance will automatically begin rebuilding the array using a spare disk. The failed drive can then be replaced and the new disk re-incorporated on the system as a hot spare.
|
|
|---|
- Hot spares should be of equal size to the main drives, and can be installed on the system following the instructions in section 3. Make sure to stop the input system as described at the start of the section.
- When installing spares on a brand new P-Series, the drives should be arranged as follows shown in the figure.
- Once a hot spare has been physically installed, click the Add Hot Spare link in the RAID/Disk Settings window to notify the
RAID controller of its presence.
- The number of hot spares in the RAID Array Status field of the RAID/Disk Settings window will be incremented.
|  Image Modified |
When an appliance with a hot spare installed detects that one of its disks has failed:
|
|
|---|
- The appliance will automatically begin rebuilding the RAID array with the spare drive, generating a RAID/Disk Issue health alert (see Appendix B for more information).
- This health alert will be updated to indicate which drive failed. The failed drive may now be replaced to become the new hot
spare.
- Once incorporated into the RAID array, the spare disk becomes a member disk and will be listed in the RAID/Disk Settings
window.
