Raid 1 config on g-tech raid thunderbold 2

I tried to reconfig from raid 0 to raid 1 my t2 - 12 tera- g-raid through macos disk utility but it works only if i select another external hd.

I would like to config as 6 tera raid1, how to do it?

You need to use the G-RAID configurator.

G-RAID configurator

After it has been converted, you then Erase it in Disk Utility.

Done, works, but the process was a little bit more complicate.
I’m describing so that it might be of help for someone else

  1. I’m working on High Sierra, and the raid drive is g-tech thunderbolt 2 (only T plugs and usb on the back)
  2. g-raid config does not see the hd in the format out of the box
  3. When new/empty I reformatted to the new file system APFS, now the G-RAID CONFIGURATOR utility sees it (after a little while)
    4 then I selected raid 1, executed the utility, and
  4. after that in MAC OS Disk utility I reformatted it as asked (for some strange reason I guess one of the partitions is still in Mac Os journaled) and the disk appears as raid with 6Tera. I hope it works as Raid1 now
  5. the process failed a few times (the Configurator gave an error message after starting the RAID1 conversion process, so I reformatted back in MAC OS journaled, and then back to APFS and started the process again)
  6. Lost the icon (minor problem)
