Tx errors on the FC port of the Fabric Interconnect

Hi Guys,

I'm seeing a lot of tx errors on the FC uplink port of the FI ( both the ports of SAN port channel). I'm trying a  EMC SAN boot one of the Blade  and it fails with IO error.

My question is if I have an issue with the LUN or EMC SP port or on the MDS port , does that cause a Tx error in the FI FC port.

Im seeeing the error counter increase when I tried to install this blade. There are other blades installed without any issue. I have chnages the SFP and cable with no luck.

To exclude any hardware issues, I would associate the SP with a blade, that worked (boot from SAN), and see if the problem moves as well.

Good luck

Tx errors on the FC port of the Fabric Interconnect

Hello Jibby,

This is clear that's a hardware issue.

Potentialy could be the: SFP (UCS/Storage), optic cord, the FI Uplink port itself or Storage FC port.

At this point you should test one by one of this layer1 related devices.
