hardware problem with this HBA?

[Jorge Pons]

Sorry
I didnt read that you test in another port

Torsten,
About HBA's light, I meant that two status light on that HBA(one for "ACT" and one for "LNK"?), not from inside the cable, "ACT" was on and "LNK" was off; from the good one(HBA", "ACT" was blinking and "LNK" was on.

Jorge,
ioscan -fnCfc was at the first beginning of this thread, and I changed the cable port to another on that switch, it remained the same.

Stephen

What remained the same?
The fcmsutil output?


An easy mothod for testing is to plug in a loopback connector, if you have one.


However, if light comes out of the transceiver (be careful, I told you!), the HBA is likely OK. If no light comes out of the cable, the cable is likely bad. Same for the switch and the other direction of the cable.

Hi

Like said Torsten, you can "test" the cable.
connect to hba and see at other connectors (carefully) if light is there. then change position of cable to see the other one.

Torsten,

The HBA's status LED and the new port's status LED remained the same.

>>light comes out of the transceiver .
what dose "transceiver" mean here?

please explain in more detailed,thanks!

I'am not an expert to "test" a cable.

The light comes out where the cable plugs in ...

HI

to test the cable is very simple (to see if its broken).
The hba (or switch port) has two "holes" one is for transmit and the other one is for receive. It means, one emited red light, and the other one receive the light that emited other device.
If you see directly this holes (hba or switch port) you can see this light, but carefully because if you see for long time, you can damage (one second, dont worry).
The cable, is made of crystal (or something laike this) and it reflexion the light from end to end, and its possible to see the light also.

for this, if you plug cable into hba and see the end of cable, you must see light. If you see light, this part of cable its ok. then you change the position of cable to see the other one.
