Question

"About this Mac" can't see RAID Drives.

I am running a Mac Os Mojave (10.14.6) on an Upgraded Mac Pro 2012 - 2 x 3.06 GHz 6-Core Intel Xeon, 64 GB 1333 MHz DDR3, Radeon RX 580 8 GB, with a 512 GB SSD as the Boot Drive. I have on board two additional 2TB HDDs Configured as a RAID 1 (Mirrored). They are set up as pretty standard GUID Partition Map drives, The RAID is Mac OS Extended (Case Sensitive, Journaled).

They Function. They Mount. Works perfectly fine. Disk Utility can "see" them, as well as Tech Tool and other 3rd party utilities. But just one weird thing. - the array does not appear in About This Mac in the Storage Tab. It's just a weird little odd thing, and makes me ITCH. The issue doens't seem to be documented anywhere.

Any ideas?

Mac Pro, macOS 10.14

Apple is dropping support for RAID...

Important notes:

Mojave no longer supports starting up from RAID volumes, including Apple’s RAID and SoftRAID volumes. High Sierra is the final macOS release with support for starting up from SoftRAID volumes. If your startup volume is a SoftRAID volume, you will need to migrate to a Disk Utility standard volume before installing SoftRAID 5.7 or upgrading to Mojave.

"Mojave no longer supports starting up from RAID volumes, including Apple’s RAID and SoftRAID volumes."

Well aware. My boot drive is the single SSD "Macintiosh SSC". The Mirrored Raid "2TB Storage RAID" are a storage volume.

Which was not my question, anyway - I was wondering what was up with the "About This Mac" being unable to 'see' the RAID Volume, it sees every other storage device I put in or connect to the machine. The RAID drives are standard HDD installed in the internal bays.

On a separate machine, running High Sierra - "About this Mac" sees all connected storage devices.

Interesting, but I knew I didn't supply the answer, was just hoping to provide clues for your end, but if a second Mac running a lower OS sees them fine then likely it's Apple causing it, but I no longer have RAID setup to test.
