Hi there,

Does anyone know if HA / fencing is possible in Dell 1950 using only the ON-BOARD Dell BMC Remote Access Service Point - supports IPMI Version 2.0?

i.e. without installing DRAC PCI cards?

If so, how would we configure this please?

Many thanks!
Ian

Hi, I have updated the wiki with ipmi doc,
http://pve.proxmox.com/wiki/Fencing

This was tested with supermicro board, but must works with all ipmi card.

Coul you test it ?

for Dell R220 without drac I used ipmilan as described in wiki and had to add attribute

cipher="3"

to make it work, by default cipher value is "0"
