I have a pegasus2 R6 12TB.
Drive 6 went bad and I replaced it. I now need to rebuild the Disk Array (degraded 12TB 0 byte enabled # of LDs 1) and the logical drive(critical 10TB raid5 strip 1 MB array of 0).
How to rebuild disc array and logical drive

Hi,
Please follow the below steps to start the rebuild on the drive.
- Make sure you hot-plug the new drive.
- Click on "Physical Drive" list in the Utility and make sure the replacement drive is showing up in the list .
- The status of that drive should be "Unconfigured" .
- If the status is "Passthru", then unlock the Utility and click on settings for that drive and change it to "Unconfigured".
- Confirm the settings ..
- Then click on "Background Activities".
- Click on the Start button next to the Rebuild.
- Select the Source drive and the Target drive and Start the process.
- It will take sometime to complete the process and you can see the progress in the bottom.
Thanks !

What is Source and Target drives? If I hot-plug the drive in bay 4 then objously I want the drive in bay 4 to be rebuilt to the RAID 5.

Hi Mike,
If you have an unconfigured drive in your Pegasus, this is how things work in the Promsie Utility.
Click the upper right hand Tab named Background Activities.
To the right of the Rebuild line, there is a Start button, click that.
If you have a degraded RAID and an unconfigured drive, you will see something like this.
The source physical drive is the array sequence drive that's missing and needs to be rebuilt. You won't be able to select anything else. The target drive is the unconfigured drive that's being rebuilt to.
Click Confirm.
Then type 'confirm' into the text box and click confirm again,. This will start the rebuild.
You will see a progress bar showing the progress of the rebuild. When it reaches 100% the progress bar will dissappear.
It's best to disable your mac from sleeping, the rebuild will stop if the mac sleeps. A rebuild that takes 10 hours to complete could take weeks to complete is the mac is sleeping most of the time.

Hi Mike,
If you hot-plug an unconfigured drive, an auto-rebuild should start.
But most new drives today are in passthru mode and before a rebuild can be done they need to be unconfigured. A passthru drive can be made unconfigured by selecting the Physical Drive tab on top, unlocking the lock in the lower-left hand corner, and selecting Settings for the passthru drive. One of the settings will be Unconfigured. Once the drive is unconfigured you can start a manual rebuild as above.
