I have tried numerous SFP+ from different vendors even purchased new 2CM32 Twinax Cables but I still do not get a link. Is there something I am missing, maybe a no shut command or something. I am extremely frustrated at this point, I am connecting to a Cisco Nexus 5010 with newest firmware.
Has the array been configured yet? Until it does the ports are down.
FYI: You will need to disable DCB on that switch if you haven't done so already. The 5010 only supports DCB with FCoE, not iSCSI.
Typically I see customers using Dell PN: WTRD1 transceiver on the 6010's.
Using Dell PN: V15WR cables
For TwinAX they must be passive, not active cables.
UPDATE: Check with some other folks and for Nexus 5010 they suggest Dell PN: H606N for 1 meter cable or Dell K591N for a 3 meter cable. The longest we support is 5 meters, Dell PN: G849N

The issue I am seeing is that there is no Light coming out of the transceivers. I cannot configure until I can get a network up link. I will order some Dell PN: WTRD1 and see if that brings the ports online, or at least get the transceivers to emit the fiber connection light. My 6510 is using 3M Dell OEM 10GBE SFP+ TurboTwin Cable PN: 02CM32 2CM32 it has the same type 10 controllers maybe the firmware is different I will have to check.
Thanks For the speedy response by the way.
OK, they are the same controllers and firmware revision would not make a difference.
Turns out it wasn't the SFP+ or Twinax cables, the ports were shut down as I suspected.
After hours of frustration, I decided to go into Boot mode ( CTRL/P) and saw ifconfig in the options decided to check out the commands:
ifconfig -i xgmac_0
I Got Starting Interface then
ifconfig -i xgmac_0 -a IP_ADDRESS -n MASK -g GATEWAY
then bam finally got a link light.
Reset the Equallogic now it is up and running.
Hopes this help any who had the same issue.
Now the issue I am having is:
2017 Jan 6 16:16:12 SMNCORE-1 %$ VDC-1 %$ %LLDP-1-NO_DCBX_ACKS_RECV_FOR_LAST_10_PDUs: No Acks have been received on Interface Eth1/9 for last 40 DCBX PDUs
after 100 DCBX PDUs the port shuts down.
Thanks in advance.
You must DiSABLE DCB on the switch. The Nexus 5010 does not support iSCSI DCB, only FCoE. The switch doesn't have the onboard H/W to support DCB with iSCSI. The 55xx series does.
Thanks, can you please point me to some documentation to disable DCBX on The Nexus 5010? I can not find any that isn't contradicting some say enable flow control some say disable flow control I keep seeing turn on PFC not LLDP and vice versa. This is the config I have at the moment it seems to be working.

This PDF has some info regarding configuring your switch to disable DCB. On newer vesions of Nexus firmware there is a global command as well. I'll check with some other folks Monday to see if they have it.
There are two kinds of flowcontrol, the traditional Link Layer Flow Control and Priority Flow Control (PFC) that ISCSI DCB uses. The later being much more granular. However, they can't both exist at same time. So w/o DCB you want Link Layer Flowcontrol on. E.g. flowcontrol send on. flowcontrol receive on.
