How to use a SoftRAID startup volume with Catalina

If you're using Catalina, and have a T2 Security chip on your Mac, then Catalina (10.15) requires SIP to be disabled first. Read this thread for more information.

"SoftRAID Volume Disappeared" notification under Mojave

I continue to get the above message every morning.
I have turned off the Energy saver buttons as recommended.

Every night, I put my Mac Pro to sleep and either wake it up manually in the morning on weekends or I have scheduled it to automatically wake up at 5:30 pm before I get home from work.

The same message welcomes me each time.

I have also received emails with the message "The SoftRAID Monitor detected a disk unplugged or stopped responding at “Mac Pro”".

I have a Mac Pro 5,1 and am using a Mercury Elite Pro Quad as my primary hard drive (x4 4TB HDDs in RAID0).
My boot drive is an internal NVME 1TB Samsung 970 EVO. I also have an internal x2 6TB RAID0 as my backup drive.

At first I was getting 8-10 of the same "SoftRAID volume disappeared" notice but that stopped when I turned off "Wake for Network Activity".

Now its down to just the one notice after i wake up the Mac Pro each day.
My other option is to shut down each day but that puts more strain on the HDDs and I want to prolong their lifespan as much as possible.

Is this a solvable issue or just something I will have to deal with as long as I use SoftRAD and put my Mac to sleep?

Solution would be much appreciated. Thanks.

Are you using built in USB, or a USB C card?

BTW: there is no statistical difference in drives that are regularly powered off, vs always powered on, or heavy duty vs light duty usage, according to the google study of 100,000 disks.

Apologies, forgot to say that I am using a 2010 Mac Pro and a Sonnet Allegro Pro USB-C PCIe card.

I also have a RAIDO with two 6TB HDDs using two internal bays. This volume does not have the volume disappeared issue.

I did not see this when I tested this card on the Mac Pro, but can look for it.

This may be something you have to live with, as it is unlikely Mac OS, Sonnet, or Mojave will be addressing this on a 10 year old computer. Just a reality of life. If this were under SoftRAID's control we would try to fix it, but it is not.
