Hello Softraid crew,

 

I have had a flawlessly performing OWC Thunderbay 4 RAID that has been performing smoothly with no issues on a Mac running OSX 12.1 and the most current version of Softraid. On Friday (three days ago),  I shut-down the machine at the end of the day, as normal, and everything spun-down with no issues.

This morning (Monday), I started-up the machine, but the RAID did not mount. At first I thought this was a fluke, so I restarted. Still no RAID.
After checking all cables, I restarted again. No RAID.

I opened-up the Softraid Utility and Disk Utility, and neither of them see the RAID, or the drives. So, how can I restore the previous raid in a situation like this? I have generated a support file, which is attached.

If the drives do not appear in the left column, it is a hardware problem. Here are some troubleshooting ideas.

Are the drives spinning up when you connect the cable? (did you try a different cable?)

Is the light on the enclosure on? Does it change from orange to green when you connect the drives?

If only one disk is inserted fully, does it spin up? Can you isolate this down to one disk that is causing a problem.?

@softraid-support Hmm. I will investigate further.
All drives are spinning, and the lights do not indicate anything abnormal (no flashing, etc). The power light is on, and functioning normally (blue) once fired-up.

I will have to see if I can isolate it further on a drive-by-drive basis. I'm at least glad to know I can rule-out the software part of the mix.

@dphilms 

Yes, you can (for now) eliminate SoftRAID. The list in the disks column is the same disks as show up to macOS. Use that as your base to figure out what is going on.
