Creating disk array - not seeing Physical Drives diagram

Hi there,

I just wiped my R8 with Promise Utility. I am now trying to set it up with RAID6. I can see all the physical drives are normal and "Unconfigured" under the Physical Drive List. When I go into the Disk Array tab, and click the Create Disk Array button, I do not see a diagram of my hard drive with the drives to select from. Anyone know what is going on?

 

Thanks!

Hi Jesse,

Lacking any informartion here, I will assume you have a recent macOS.

My best guess is that you have an old Promise Utility. You should be using 4.06.0000.04.

Or you can create a new array+LD quickly from the command line with this command.

array -a add -p 1~8 -l "raid=6"

After this you will need to use Disk Utility to put an HFS+ filesystem on the LUN.

Please do not use APFS. APFS is apparently designed for use with flash devices, not spinning disks.

Hi RP,

Appreciate the fast response. I am actually on a macOS on 10.14.6, so quite a while back. I was not able to install the 4.06.0000.04 Promise Utility because of that. I think I installed 402000017. On the finder level, my computer does not recognize the now-wiped Pegasus R8. Am I still able to use that terminal code to create a raid drive? Appreciate any ideas you have to help me troubleshoot this.

OK. My goto for older computers is 4.06.0000.01, but I'm not sure it will work with Mojave.

On the finder level, my computer does not recognize the now-wiped Pegasus R8.

Finder can only see mounted filesystems, if all the disks are unconfigured that's expected.

Am I still able to use that terminal code to create a raid drive?

This should work. Open a terminal and enter promiseutil to start the CLI. The command must be run in the Promise Utility CLI.

You will still need to use Disk Utility to put an HFS+ filesystem on the newly created LUN. In Disk Utility select the Pegasus disk and use the Erase function. Make sure you have the correct disk selected.

I ended up borrowing a friend's laptop that could run the newer version of Promise Utility. I used that to create the RAID6 drive. The drive is now connected back on my machine as it continues synchronizing.

Thank you very much for your help!
