Prevent application (iscsiadm) logging to dmesg?

Question

I have an issue where running sudo iscsiadm -m discovery -t st -p IP -l logs to dmesg across all terminals on the server.

The command is run from a java application, using:

    Runtime.getRuntime().exec("/bin/bash", "-c", "sudo iscsiadm -m discovery -t st -p *IP* -l");

I have tried the following:

1. Apppending > /dev/null 2>&1 to the end of the iscsiadm discovery... command
2. Capturing input streams from the returned progress (process.getInputStream() and process.getErrorStream())
3. Appending > /dev/null 2>&1 to the software launching the Jar.

None of the above attempts prevent logging across all virtual terminals. The log starts [some_num.some_dec] LOG_MESSAGE which suggests it is outputting to dmesg? If this is true how do I prevent this? Currently it makes the system impossible to debug because it's printing over the terminal prompt.

Thanks

Issue fixed.

It turns out it was not iscsiadm logging to dmesg, it was the mount command afterwards because the blockdev did not exist.

I have modified my java code to try iscsiadm -m discovery... then run iscsiadm -m session to determine if the appropriate device has a connection or not prior to mounting.
