Dual Port Sas Drives show up twice

[schwartznet]

Im new to Dual Port sas. I have 14 15K 300GB sas drives on my freenas and have been connecting them to only one port. Someone explained that they can utilize two and told me to try that. I connected the second port but now the drives show up twice when i go to create any volume. Am i doing something wrong? my chasis is
SuperChassis 846E26-R1200B and it has 6 SAS connections. I read the manual and plugged the sas cable into the correct port (so i think). Any insight would be great

If you have multipath configured correctly you should see a "view multipath" in Storage → Volumes → View Multipaths. This is covered in detail in the freeNAS manual.

The manual says it automatically detects it and will show up but there is nothing that says view multipaths

 

[Mlovelace]

To quote the manual "If the system has multipath-capable hardware, an extra button will be added to View Multipaths."

I would infer from the lack of auto detection by freenas that you do not have multipath configured correctly on your system, as per the Supermicro manual, your server supports SAS multipath.

Edit: Are you using dual HBAs or single?

LSI 9211 IT Mode (M1015) single atm but i have two on hand

Typically SAS MPIO would use dual HBAs, although you can do redundant cabelling to a single HBA, it wouldn't give you the same fail over protection as a redundant HBA. So, as I recall you would connect J0-A to HBA1 and J0-B to HBA2, but double check you manual.

Edit: how did you cable the single controller?
