Sunfire x4600 M2 NIC replacement

Hi All,

I am having an Sun fire X4600 M2 server where one of the interfaces is down.
I had requested for the replacement but had a bit problem in identifying the port.
As per the server service module, there are 4 NIC ports and one port is not flashing (e1000g0) but as per server, the port e1000g0 is fine but e1000g2 is down.

Also as per service manual, there are only for ports for this server but in the server output, i have 6 interfaces.



Code:
e1000g0         link: up        speed: 1000  Mbps       duplex: full
e1000g1         link: up        speed: 1000  Mbps       duplex: full
e1000g2         link: down      speed: 0     Mbps       duplex: half
e1000g3         link: up        speed: 1000  Mbps       duplex: full
e1000g4         link: up        speed: 1000  Mbps       duplex: full
e1000g5         link: up        speed: 1000  Mbps       duplex: full

e1000g0: flags=xxxxxxx<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
e1000g0:1: flags=xxxxxxx<UP,BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4,NOFAILOVER> mtu 1500 index 2
e1000g1: flags=xxxxxxx<UP,BROADCAST,RUNNING,MULTICAST,PRIVATE,IPv4> mtu 1500 index 7
e1000g2: flags=xxxxxxx<UP,BROADCAST,MULTICAST,DEPRECATED,IPv4,NOFAILOVER,FAILED> mtu 1500 index 3
e1000g3: flags=xxxxxxx<UP,BROADCAST,RUNNING,MULTICAST,PRIVATE,IPv4> mtu 1500 index 6
e1000g4: flags=xxxxxxx<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 4
e1000g4:1: flags=xxxxxxx<UP,BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4,NOFAILOVER> mtu 1500 index 4
e1000g4:2: flags=xxxxxxx<UP,BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4> mtu 1500 index 4
e1000g5: flags=xxxxxxx<UP,BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4,NOFAILOVER> mtu 1500 index 5
e1000g5:1: flags=xxxxxxx<UP,BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4> mtu 1500 index 5
e1000g5:2: flags=xxxxxxx<UP,BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4> mtu 1500 index 5.

Could you please help me in understanding this and how to proceed further with this to replace the NIC cable.

Regards,
Rocky

Please post the output of prtdiag -v and dladm show-dev.
The dladm command can differ, depending on the Solaris version you are using.

I would say you have an extra PCI card with two network interfaces in your system.

Check the device pathes to your NICs in /etc/path_to_inst and see if one of the onboard devices is e1000g2. Here is a list of the onboard NIC device path:


Code:
Network 0 (e1000g0)   /pci@0,0/pci1022,7458@10/pci8086,1011@1
Network 1 (e1000g1)   /pci@0,0/pci1022,7458@10/pci8086,1011@1,1
Network 2 (e1000g2)   /pci@0,0/pci1022,7458@10/pci8086,1011@2
Network 3 (e1000g3)   /pci@0,0/pci1022,7458@10/pci8086,1011@2,1

Duke,

I was able to get the data from path_to_inst but could not understand this.


Code:
"/pci@0,0" 0 "npe"
"/pci@0,0/pci10de,5d@e" 3 "pcie_pci"
"/pci@0,0/pci10de,5d@e" 1 "pcieb"
"/pci@0,0/pci10de,5d@e/pci108e,125e@0" 0 "e1000g"
"/pci@0,0/pci10de,5d@e/pci108e,125e@0,1" 1 "e1000g"
"/pci@0,0/pci1022,7458@10" 1 "pci_pci"
"/pci@0,0/pci1022,7458@10/pci8086,1011@1" 2 "e1000g"
"/pci@0,0/pci1022,7458@10/pci8086,1011@1,1" 3 "e1000g"
"/pci@0,0/pci1022,7458@10/pci8086,1011@2" 4 "e1000g"
"/pci@0,0/pci1022,7458@10/pci8086,1011@2,1" 5 "e1000g"
"/pci@0,0/pci10de,5c@9" 0 "pci_pci"

Instance 2 of e1000g is the one that is not working. This is the first network port on the motherboard assembly of your server... So, you need to check the cable and the switch port which is running to the net0 port on the server (not PCI slot), should be the bottom left! If everything is ok and the port is still not working, the port might be dead and you need to replace the servers mainboard.

Duke,

I had requested a check and media team person also says the same(bottom left) port is not blinking and that is the one which needs to be replaced.

But my doubt is that when i went through service manual of this server(could not paste the pictures), it says bottom left is e1000g0 and upper left is e1000g2. So as per your analysis and service manual, e1000g0 should be replaced but the server says e1000g2 is down.
I am totally confused at this stage as to how to proceed also when i hit dladm, it shows 6 devices now from where did the other two come into picture when the server has only four ports.

I am very much afraid and much taking so much clarification because this is a prod and there is no link aggregation.
