[Freeipmi-users] ipmipower : How long does it take for a power off?

Hello,

Greetings! Hope all are good.

I am new to ipmi and starting to experiment with a HA cluster using
pacemaker and I have everything working fine but the fence agent is
the bottleneck....

Using ipmipower to turn off the power works great and the
--wait-until-off is super useful.

my example test command:

time(ipmipower -D LAN_2_0 -h 10.x.x.x --off --wait-until-off)

My question is that it takes about 5 seconds to complete the command.
Maybe this is normal?

I used the "ipmi-config" tool (also very useful) to turn off the
"Per_Message_Auth" as I heard that could slow things down. I also
tried lower "Retransmission Wait Timeout"  but I always seem to be at
5 seconds...

Any suggestions to speed this up?  My guess is the problem is an old
IMM unit and not the software but wanted to check and see if anyone
has experience with this and any tips.

Thank you very much and take care

Steve
