The Promise Utility will advise you which HDD module failed and you need to make a note of that Bay slot number before turning the system off. Follow these instructions

Prior to beginning the steps please make sure you are using the latest Promise Utility. You can download the Promise Utilty here. Free dsp software.

Go ahead and Open the Promise Utility

Providing a perfect entry point for users needing HW RAID protection with adequate capacity, the PROMISE Pegasus32 R4 series RAID storage system brings the power of Thunderbolt 3 technology to a wide range of Mac users. Promise Pegasus R4i delivers the powerful RAID engine from the Pegasus as an internal four-bay RAID MPX Module for Mac Pro. Get the blazing speeds essential for your high-resolution video and rich media projects, along with the safety and security of a full-featured hardware RAID engine. The Pegasus32 R4 is ready to use out-of-the-box, with the 16TB model offering four 4TB SATA 7200 rpm drives. Both models include Promise Utility for setup, management and monitoring, as well as a three-year limited hardware warranty and 24/7 online assistance. My recent purchase of the Pegasus2 R4 disc-less drive has been a mixed experience. The drive is certainly well made and has worked correctly and quietly from the start. However, the utility software that is required to set up a Raid or otherwise monitor/modify the external drives has never functioned.

Soon as you open the Promise Utility it will scream something is wrong. Note**If you see this informational message below, we advise to not accept and then shut down the Mac Pro 2019, finally, reseat the Promise R4i hard drives. There could be a slight chance that the drive did not detect on boot. Reseating and rebooting your Mac Pro will sometimes correct these problem. However; if this screen pops up again, please accept continue with the steps as there could be a dead drive.

Once you've accepted you will notice in the home page dashboard, under the label 'system status', the disk array and logical drive have an 'red circle' on each of them. If you look under the label 'storage overview' you can see that there are 3 drives listed. In the label 'Event Information' you will notice the Logical drive has been set to critical due to the missing drive.

We will confirm the drive is dead by checking the other settings.

Under the Physical Drive Icon you will notice that a Physical Drive is missing from the list.

Elite panaboard software. In this image we are looking at the Disk Array information. Notice the operational status as Degraded.

In this image is the logical drive. The operational status is 'critical' which means that the volume is usuable, but if another drive fails than it will be catastrophic.

Now we've identified that the drive is indeed failed.

Go to the icon --> Disk Array --> highlight select disk array --> than to the far right there are three dots to extend the options. Click on the rebuild and proceed to accept.

Once the rebuild has begun you can monitor the rebuild in the daskboard.

3Please note** If the rebuild does not appear or fails, contact support immediately. Support contact information -> https://support.promise.com/, or call 408 228 1400 option 4

HI - I installed Sierra OS which did not recognized my Pegasus 2 R4 system. after many calls to Apple and then, some technical support with Promises they informed me that my #1 HD was failing and that I should replace it.

So, now I have purchased and installed the new HD into my Pegasus 2 R4 system, and have it plugged into my Mact with Seirra OS. The system needs to recognized the new HD and I do not know how to install the system so the RAID 5 is working without loosing the data on the other 3 HDs that are still working well in my system??

Can someone please give me step by step instructions to rebuild this new HD in the RAID 5?

I do not want to erase the other 3 HDs since they have my Data on them, and simply want the new HD to be recognized as part of the RAID 5 so, I can continue working as normal.

I was going to try follow the Wizard to set it up, but am afraid that I may do it incorrectly, and I also need to ensure that the HD are set up as 'Mac OS Extended (Journaled)'.
