Hi users, I have setup OVIRT 3.5 with* 2 REDHAT 7.1 hosts.* Everything is ok other than HA ( High Availability). To test HA, Documentation says, *Power Management is needed. * Could you pls let me know if this Power Management is a separate Device or does it come with a BRANDED Server such as HP, IBM or Dell? I have seen a* ILO* port in HP servers. Can I use it for HA ( High Availability) in ovirt? If *power management* is *present in Branded Servers*, Could you pls let me know some *Branded RHEL 7.1/CentOS 7.1 supported servers?* Then, I can use it for Production use. *This is an YOU TUBE video for HA.* https://www.youtube.com/watch?v=uHCnXGUMaS0 Is this a correct video for HA? I did some research. a few URLs. http://lists.ovirt.org/pipermail/users/2013-January/011519.html http://www.ovirt.org/OVirt_Administration_Guide#Host_Resilience https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualizat... *what is **Soft-Fencing Hosts ?* ovirt doc gives below . ( http://www.ovirt.org/OVirt_Administration_Guide#Host_Resilience ) Soft-Fencing Hosts Sometimes a host becomes non-responsive due to an unexpected problem, and though VDSM is unable to respond to requests, the virtual machines that depend upon VDSM remain alive and accessible. In these situations, restarting VDSM returns VDSM to a responsive state and resolves this issue. oVirt 3.3 introduces "soft-fencing over SSH". Prior to oVirt 3.3, non-responsive hosts were fenced only by external fencing devices. In oVirt 3.3, the fencing process has been expanded to include "SSH Soft Fencing", a process whereby oVirt attempts to restart VDSM via SSH on non-responsive hosts. If oVirt fails to restart VDSM via SSH, the responsibility for fencing falls to the external fencing agent if an external fencing agent has been configured. *BUT, It does NOT say how to set it up? * *is there any step by step doc for it? * HOPE TO hear from you? -- cat /etc/motd Thank you Indunil Jayasooriya http://www.theravadanet.net/ http://www.siyabas.lk/sinhala_how_to_install.html - Download Sinhala Fonts
