June 30, 201214 yr I have two X9SCM motherboards, one works flawlessly. The other, unRAID wants to use LAN2's MAC address even if I plug it into LAN1's port. LAN1 port works fine, I can IPMI to it and see that unRAID is fully booted, and then I can use ifconfig to see that it's pull the wrong MAC address. How do I fix this when there is no way to disable LAN2 in the BIOS? syslog.txt
June 30, 201214 yr Is that from within the console itself, or when you're attempting to communicate to it from another computer? If the latter, then you may have to update your router and/or computer as to the correct MAC.
June 30, 201214 yr Author Is that from within the console itself, or when you're attempting to communicate to it from another computer? If the latter, then you may have to update your router and/or computer as to the correct MAC. unRAID seems to take over and force it to use LAN2 MAC address. I can't specify to change this in my router. unRAID uses the first MAC address it finds, and it found the wrong one. I see no way to get it to use the other one. LAN1 works fine, if I put another OS on the server and boot to that.. it works flawlessly. unRAID is forcing LAN1 to use LAN2's MAC address, which renders the port useless. I'm forced to use LAN2 which does not have IPMI.

If so, get rid of it (delete it) OR change it to the MAC addr you wish used. Then, reboot. If not present, you can add one like this: HWADDR=00:11:12:7E:11:6C Joe L.

Maybe I misunderstand you.

Did you delete the existing (incorrect) line, or add one with the MAC address you wish used?
July 2, 201214 yr Author Did you delete the existing (incorrect) line, or add one with the MAC address you wish used? There was no line, I added a new line with the MAC I wanted it to use. Do you have the the X9SCM or X9SCM-F? The X9SCM-F has IPMI integrated on the board and a dedicated port for IPMI plus LAN1 and LAN2. Maybe I misunderstand you. I have the X9SCM-F. It has a dedicated IPMI port, and it's integrated into LAN1 only (to my understanding). I have not been able to get IPMI to work on LAN2 on either of my boards, it might be a BIOS setting. unRAID successfully is using LAN1 now after adding the MAC address to the network file so I don't need to use LAN2 now.
July 3, 201214 yr It didn't work for me: I have the SUPERMICRO MBD-X9SCM-F-O. I changed the HWADDR and it still wants to use LAN2. All it did was spoof the mac of LAN1 now.. any ideas?

July 6, 201213 yr yeah... that was my first thought.. but the Supermicro board doesn't have that option in the bios..
July 16, 201213 yr Author yeah... that was my first thought.. but the Supermicro board doesn't have that option in the bios.. Don't feel bad, it's no longer working for me either. I don't know why, I gave up on it. Worked for a few days then switched back to the other NIC. I'm very confused on how unRAID can't detect 2 NICs. There is no way to disable NIC2 in these BIOS, I called Supermicro and they said you can't. Just going to have to move the cable each time I use IPMI... This really could use a fix, I suspect it will be fixed when we can daisy chain because then unRAID is forced to use both NICs. Look under southbridge configuration. You'd think so, but nope. Most i've heard is that there's a jumper on the board to disable it but i've found no documentation to prove it. EDIT: After some more search there are indeed jumpers to disable NICs. Check page 2-31 of the manual.
July 16, 201213 yr EDIT: After some more search there are indeed jumpers to disable NICs. Check page 2-31 of the manual. Yup. i said that in the other thread on this topic. supermicro uses hardware disconnects on the nics instead of software (bios) on their boards. A few users have turned off the second nic using this method.
