<div dir="ltr"> <div>Hi guys! Thanks for the input. I've had a second look at the backplane and you were right Chris, it's not dual port. Should i set mpxio-disable="yes" to disable mpxio on the sas driver or should i leave it as is? My guess would be to disable mpxio to actually see which controller holds which disk, this to be able to spread the mirror-sets across multiple controllers. Would you agree?

Supermicro will sell you the same chassis with or without expanders, with almost identical model numbers. You’ve described a typical JBOD configuration (i. e., no expanders): Each LSI 2308 has 8 SAS/SATA ports, 4 ports on each of 2 Mini-SAS SFF8087 connectors. Thus, with 3 controllers you are running 3 x 8 = 24 SAS ports to the backplane. Do you have the exact model number of the chassis or backplane?

I'm having issues with multipathing, and i cant seem to figure out what is wrong. The setup is a Supermicro 24 disk-box with 3 controllers (1 pcs internal SAS2308, two 9207i-cards, same firmware on all units), identified as follows: Num Ctlr FW Ver NVDATA x86-BIOS PCI Addr ---------------------------------------------------------------------------- 0 SAS2308_2(D1) 18.00.00.00 11.00.00.05 07.33.00.00 00:01:00:00 1 SAS2308_2(D1) 18.00.00.00 11.00.00.05 07.33.00.00 00:02:00:00 2 SAS2308_2(D1) 18.00.00.00 11.00.00.05 07.33.00.00 00:03:00:00 The machine has 12 ST4000NM0023 (seagate 4TB DP) disks in it and a couple or bootdisks. The controllers are connected via 2 cables per controller to the backplane/expander. I've Installed latest stable omnios on it.
