Bad Rx Char

[Gilbert Plouffe]

What could be the reason behing having high Bad Rx Char counts

[Torsten.]

Let's guess about the background of this question ... related to LAN, FC or what?

Bad signals in general may have bad cables, connectors, sender or receiver modules as a reason.

Sorry for the lack of info

it is related to FC

I am monitoring with EVA perf controller ports of an HP EVA 8000. I noticed that there were some Bad Rx Char on all my ports and just was wonduring what could cause these problem and where to start.

thank you

What you mean by "some"? "some" could be pretty normal if this is a low value.

FP4 Host Up 2 510

MP1 Mirror Up 0 19
MP2 Mirror Up 0 26

Controller 2

I just notice that these Bad Rx Char errour did not change after one hour of monitoring it could have been there before.

Are you aware if there is any documentation available that could tell me what is these errors rate are normal?

I've attached a text doc and also included it's url in case. Usually Bad Rx Char is hardware related and fixed by replacing the fibre cable. If you have alcohol and a paper towel you can also try cleaning the ends. I was taugth to wet the paper towel, followed by 6 or so veritcal swipes and 6 or so horizonal swipes. Also, the numbers given in this example are 7,500 and up.
