Yesterday I received 2 LSI 9207-8i HBA cards. I've bought them on Ebay for a nice price. My question I've connected them dual link. Are the cards automatically using dual link or do I have to set something?

 

Connected them to what?

 

I connect one of my cards to a true expander with dual cables Dell H310 with both ports connected to 2 of the six on a RES2SV240, then four out of the RES to drives

Yes, if the expander supports it, you can check with:

 

cat /sys/class/sas_host/host1/device/port-1\:0/sas_port/port-1\:0/num_phys

You need to replace host1 with the correct one, post your diags if you can't find it.

 

If result is 8 then it's using dual link, 4 means single link.

Interesting, didn't know that.
