MvL Posted April 29, 2018 Share Posted April 29, 2018 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? Quote Link to comment

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 Edited April 29, 2018 by CHBMB Quote Link to comment
MvL Posted April 29, 2018 Author Share Posted April 29, 2018 Oh yeah sorry, I connected them to a expander backplane of my 24 bay server chassis. Quote Link to comment

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. Quote Link to comment
MvL Posted April 30, 2018 Author Share Posted April 30, 2018 It's reporting a 8. So it's dual link. Thank you Johnnie. Quote Link to comment
