Thunderbay 4 and MacOS Boot Volume

Henry-In-Florida · 2017-06-20T02:41:37Z

Hi, I have a Thunderbay 4 configured as a RAID4 array and a Boot Volume. I recently had a bootable OS installed and working fine attached to an older MacBook Pro (11,3). Then I upgraded my MBP to a new version machine, and my troubles began. I also upgraded the Softraid to 5.6 driver. Now the MacOS volume which is not part of the RAID4 but is formatted in SoftRaid is no longer recognized as a boot volume. How can I fix this? I read another thread that says that CCC must be used to clone a bootable version of MacOS onto the drive. Apple tells me that a RAID array cannot be used to boot or install a bootable OS. Well, this drive is not part of the array but is formatted with SoftRAID. Apparently this is an issue with Sierra. Can you help sort this out? Do I need to start a clean install and reformat with Disk Utility? Thanks for any advice on how to proceed with my apparently now broken install.

It is easier for complicated problems to deal with support emails.

It appears that your volume is not recognized by OS X as having a valid boot volume on it. Lets work on this off line.
