RE: [Linux-cluster] fence_apc 7930s

Ok... I screwed up.  I figured it would be my mistake in the end.

I renamed the outlet to the hostname of the system a while ago.  I change
the name back to the default "Outlet #" and fence_apc worked the first try.
I always use the port number and not the name, but maybe I broke something
by changing the port name on the apc devices.

I have a 2 node cluster now with fencing across two apc 7930s using
redundant power supplies.

Thanks everyone for the help,

What do you mean by multiple 7930s...do you mean daisy-chained together? 
Like a Master Switch Plus APC switch? I cn find no info on the site for 
ganging these switches.

There are 24 outlets in this beast, though.

If you have multiple apc 7930s, you could just set up each one with its 
own address, and make each one a fencedevice. Granted, you can't really 
shut down all (or a combo of) outlets on all switches with one command - 
but is that really what you need to do?

Are you trying to, say, turn off outlet 2 and outlet 4 on one switch at 
the same time? This can be done either by outlet grouping using the apc 
interface, or by using two <device> entries within one <method> block in 
the conf file...in fact, s-c-cluster will detect this condition and make 
certain that they are both off before turning either one back on.

Are you trying to turn off outlet 2 on ap 7931 - switch1, at the same 
time as outlet 2 on ap 7930 - switch2? The only way to do this is to set 
them up in the same method block as described above.

Is this helping? I am sorry if I am missing your point...:/
