MUX not recognized with ioscan on HP 11.11 D270 server

[Debbie Fleith]

I have a system with an HP PM16-DB mux, Part # J2485-60010. It doesn't show up as a device under ioscan. The light to the internal mux card is on in the back of the server, the power to the mux port card is on, but the "Active" light next to the first port on the port card is off.

I have configured all of the drivers into the kernal that normally apply to muxes.

Do I possibly have a hardware problem with the mux port card?

Hi Debbie,

Can you attach your ioscan output for us to look at.

ioscan -fn

Thanks

Hi Debbie:

I'll take a guess. It is possible to run 64-bit 11.11 on your D270 but not with EISA cards.
Have you installed 64-bit 11.11 and trying to use it with your EISA MUX card?

[Debbie Fleith]

Sure. Here it is

[Debbie Fleith]

I installed HP 11.11 32-bit on this server.

Hi,

Just i wild guess.
Try insf -e (Refer man pages of insf)

-USA...

Ok, it appears that that the mux card is in slot 1. Unfortunately, I don't have a D-box with that card in it running 11.11. The closest thing I have is 10.20 running the 8-port version. It uses the eisa_mux0 driver. I suspect that you are missing the driver.

Hi debbie,

Do you have mux2 and mux4 enabled in your kernel.

What is the HP Part code for this card ?.

Thanks

[Debbie Fleith]

I had to add mux2 and mux4, but yes, they are now configured into the kernel.

[Debbie Fleith]

The Part # for the mux is J2485-60010

Hi Debbie:

Bear in mind that you must install the EISA RS-232 MUX Software from one of your application CD's.

Thank-you all.

I did not have the EISA MUX software installed, but now do and the mux is recognized.
