Topic: Sata Drive Support

[Bud]

hope you guys can help

I have built a NEW SME 7.51 server with 4 x 1T WD Sata Drives

Sata 0 and Sata 1 is used for Email, User Files, Database Access etc. with Raid

Sata 2 and Sata 3 are used for Data and Backups (Sata 2 for Other Data) (Sata 3 for Backups)

My Problem is that the Raid is Working (I think) and I THINK I have Sata 2 Up and Running for Data Storage

I just am not sure that I have the Sata 3 Drive up and Running. I am a bit confused about checking this:

This is my Current Setup

...I THINK I have Sata 2 Up and Running for Data Storage
I just am not sure that I have the Sata 3 Drive up and Running. I am a bit confused about checking this:

I think you need to tell us more about how you physiclly set this all up. eg Did you install the RAID only initially with only two drives connected, and then follow the Howto to add the other two drives ?

I suspect you may have a RAID1 with two drives plus a hot spare, and then "data" on the 4th drive.

Or log in on the console or Putty SSH using the admin username and use the configure RAID menu.
