Hi al,
New here, thank you in advance for any help.
I have a Pegasus R6 with 6x 3TD Baracuda drives. I want to fully reformat the raid and use it for long term file backu; for video footage.
What is the best way to make sure the unit is completely wiped and what is the best configuration to set up for this use? I was thinking to have 5 of the drives set up with an array and one drive set to physical drive, is this correct?
Thank you!
Hi Niko,
The easy way to wipe the storage is to use the CLI. Open a terminal and type 'promiseutil' then use the 'init' command as illustrated.

To change the current HBA/Subsystem path, you may use the following command:

This will delete the partition information on the disk, you will then have to use diskutil to put a new hfs+ filesystem on the disk.
As always, be careful with the CLI.
If you want to make changes to the array configuration you will have to delete the existing array first, then you can create a new array. The Promise Util GUI might be easiest here. But you should do the init before deleting the array.
