Hi, i'm new at unRAID, and i'm trying to build a 12 bay unRAID server. The mainboard (Supermicro X7SPA-HF-D525) has 6 onboard SATA II ports, and i've added a Supermicro AOC-SAS2LP-MV8 8 port SATA III controller. For testing, i've connected a Hitachi 4TB disk to the SAS2LP controller.

 

According to the various user manuals, you should be able to see all disks/controllers with the

dmesg|grep SATA|grep link

but the command only shows the 6 onboard SATA ports (see image).

 

The preclear script (using the -l ) option) does recognize the disk, and i can assign the disk in the web interface.

Should i worry about this?

syslog.zip

The manual pages you read are out of date.    The command you used no longer will find all the lines in the syslog that identify disks.

There is nothing wrong with your disk or your installation, it is just that linux has evolved since when that manual page you read was written.

 

Your disk controller is showing itself as an "sas" device in the syslog, not an SATA device:

Good luck with your server.  (Nice 4TB drive!!!)

Ok, great! It's now pre-clearing, and if that goes well, i'll be adding 5 or 6 more 4TB drives
