EVA4400 - Controller with error


We have an EVA4400 and one of the HSV300-S controllers shows an error:


And some of the IOs modules shows also an error. But not all of them.


How can we check where is the problem? We don't know if it's a controller error or if it's some IOs modules errors. Our EVA is not in warranty (we don't use it for production) and we will fix it.

Hi there,

As far i can tell from the pictures some of your FC I/O Modules are probably dead...

We have the same storage and we are 'replacing" these modules every year for the last 3 years now..

Unfortunately our storage is still in production and as we do not have support, so we are "shopping" used parts...

Dear Mgfeal,

Good day!

The right controller has degraded health condition which might be contributing or causing loop issues. There is no DP-1A or DP-IB LEDs either.

The connection status is:
Right controller DP-1B (O) > Enc 5 P1 (O), P2 (G) > Encl 4 P1 (G), P2 (G) > Encl 2 P1 (O), P2 (F) > Encl 6 P1 (G), P2 (G) > Encl 1 P1 (F), P2 (G) > Encl 3 P1 (), P2 () > Left controller DP-1B

*O=Off, G=Green, F=Fault.

*Not sure of encl 3 right IO P1-P2 LEDs. Hence, blank above.
*On Encl 3, left IO, the P2 is off, if cabling is right, it should be connecting to right controller DP-1A.

The loop 1B is disrupted. If any IO module or cable is malfunctioning, the loop error would traverse across the components on loop.

I would request log file (and above missing LEDs) to verify array hardware status. It would help us pproceeding methodically.

Also, do you have spare IO module or cable at site?
