From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.2.7 (X11; Linux i686; U;) Gecko/20030131 Description of problem: Appendix A from 'rh-cm-en-1.0' (2002 version) inccluded info on using a WTI power switch to power on/off multiple ports at once. This is useful for setups where a server has redundant power supplies. I am unable to find this info in the curent rh-cs(EN). Can you please add that info again? Version-Release number of selected component (if applicable): rh-cs(EN)-3-Print-RHI (2004-06-04T17:42) How reproducible: Always Steps to Reproduce: 1. configure WTI power switch so that two ports have the sanme name 2. test manually 3. configure in redhat-config-cluster Actual Results: Curently the guide lacks info, thus making people believe that we cannot fence a server with redundant power supplies Expected Results: Info in the current guide as it was present in the 2002 version. Additional info: (WTI network attached power switches, WTI NPS 230 in this case, can operate multiple ports for fencing if ports are named identical.
