Thanks for the clarifications Dave, now I got it working and stonithing the LPARs ;-) Finally I chose the public key authentication, don't feel comfortable with the hscroot password in the heartbeat configuration. One final question: "man chsysstate" or the redbook sg247038 don't show anything about the options --immed and --restart, any other public source of documentation for these? Thanks again. _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
