For these reasons, I always recommend power > fencing (IPMI, PDUs, etc). how does power fencing change your first 2 statements in any fashion ? as I see it, it would make manual recovery even harder, as you couldn't even power up the failed system without first disconnecting it from the network When I have used network fencing, I've left the admin ports live, that way, the operator can access the system console to find out WHY it is fubar, and put it in a proper state for recovery. of course, this implies you have several LAN connections, which is always a good idea for a clustered system anyways. -- john r pierce 37N 122W somewhere on the middle of the left coast
