Remove the failed disk and put in a new formatted disk.
It will say ‘Pass Through’
Click on the drive and change from ‘Pass Thru’ to ‘Unconfigured’
Now click on ‘Rebuild’ and it will rebuild the failed disk from the other disks.
wait for it to finish – 3-6 hours!
Hey man, thanks for this. I’m kinds stuck in another situation! more than 1 disk failure. I was in the middle of changing desktop setup, and cleaning up the dust. I opened one of the hard drive bays by mistake (STUPID) and saw a lot of dust. and I was putting them back they turn red. and cleaned more, so 5 out of the 6 drives turned red. And when I opened the Pegasus utility it shows that 5 out of the 6 drives Status is dead. and all show the right capacity as 2 TB except for one that shows 0 bytes.
This is obviously making me nervous, as everything I have and have been working on, including clients work is there. with no other backup. And I’m wondering if there’s a solution to retrieve or fix this.
I appreciate an urgent response,
Thank you,
Thanks! this helped me a lot!
You rock Wayne!
Thanks for this simple tutorial! The Pegasus manual and other instructions online require a rocket science degree. Only difference is my rebuild is taking much longer; it’ll probably be about 24 hrs to rebuild one 4TB drive.
I am nit able to rebuild as it states ‘Incomplete/Missing PD’
Any ideas what to do?
Why would ‘Start’ under Rebuild be greyed out? I have set the drive to Unconfigured. I am upgrading my Pegasus R8 from 3TB drives to 6TB drives. Thanks in advance.
I think you may have to click the lock to unlock it and put in your password to allow the greyed out actions.
Thanks Wayne
If Pegasus Manual could be that clear and simple!
I know technology, but frankly , after reading the manual almost from cover to cover, I couldn’t even get to activate the greyed Rebuild button… frustrating.
Now rebuilding a failed 3TB drive in a pegasus R4 RAID5 thanks to you.
Smile coming back.
I replaced my drive, the R2 went all blue, I made unconfigured, but it won’t start the rebuild. Says “Failed to start rebuild: all the logical drive on the array are eitehr online or offline”.
Not very helpful, obviously it would be one or the other… and there doesn’t appear to be anyway to force it online. Argh.
One of my drives were listed as PFA, so I replaced it.
I have the same problem as Paul Burgess above. I have unlocked Promise Utility, but the rebuild button is greyed out and the “Disk Array” tab says “Incomplete array found in the subsystem” and “Incomplete, Missing PD”. I’ve replaced drives before, without problem. Any clues would be helpful.
Thanks much for the easy reminder. I got my R8 to start rebuilding.
