consider a function like getSubsystemByNqn or maybe https://pkg.go.dev/sort#Find

          > With a function, I see the following benefits:

for sure. But in this case I'm not sure it is much simplified or less code...
I don't want to log in the function... but I can construct the error message... but not ideal as well...
I was thinking of a more useful function like getSubsystemByNqn but doing this vs simple loop, not sure what is more helpful...
maybe using https://pkg.go.dev/sort#Find ? need to read more...
