[Fixed in 1.3.0] Cisco MDS91xx NX-OS failing discovery

I have an MDS9124 fibre channel switch running Nexus NX-OS 5.2(8i). It's an old device, but Nexus shows on the supported kit list.
How do I debug why it's failing?

The NXOS driver was developed against NXOS 6.0 and 6.1.
There might be some differences in 5.x that make in incompatible.
Please run Unimus in debug mode:
Code: Select all
service unimus stop
cd /opt/unimus
java -jar Unimus.jar --logging.level.net.unimus.core=TRACE --unimus.core.echo-ssh=TRUE --unimus.core.echo-telnet=TRUE
It will output logs into the console.
Please run a discovery, and post the log here, or PM it to me.
(strip any sensitive information)
Thanks!

Hi Tomas,
Thanks - that will probably be the answer. I sent you a PM with the debug output, but we are literally about to replace these devices with updated models, so unless you're keen to add support, don't bother on my behalf.
Thanks,
Richard

Since it's a Cisco MDS, Unimus didnt pick it up.
(since we had support only for Nexus specifically until now)
I added support for MDS, and generic NXOS support, which will be available in 1.3.0.
Also sent you a PM with a dev build which contains support.
Thanks for the debug output!
