[Linux-cluster] fence_ipmilan

[jose nuno neto]

HI
Thanks for the info

I'm having other fencing problems with fence_ilo and I'm thinking of
writing a script to do the fencing, ipmitool works fine, I'll just write a
script to call it. what do you think?

Also, I'd like to know what fencing solutions are the most common, reliable.
I'm doing a proof-of-concept for a big institution and would like to know
what are the more stable solutions

Best Regards
Jose
