[rancid] HP Switches Stacked

[Big Wave Dave]

I have been monitoring an HP4104GL and HP2824, without issue, for many
months.  Last week the admin of the devices decided to configure them
in a "stack"... managed on one IP.  Now the hlogin seems to be
failing.  When run on the command line it gets to the prompt to select
the switch.  I'm confident this is causing the problem.  Is there a
way to pass the stack member/number?  Is there another solution,
besides unstacking?

Thanks,
Dave
