C6220 IPMI raw fan control no longer working?

[rmzg]

So I got a C6220 version 1 earlier this year with 4 nodes and things have been pretty great, except for the fan noise. So I did a lot of googling and eventually found this post: [Poweredgec-tools] C6220 ipmi fan speed raw command?

Which says:

ipmitool -I lan -H <IPMI-IP> -U root raw 0x30 0x19 0xa0 0x00

ipmitool -I lan -H <IPMI_ADDRESS> -P <IPMI_PASSWORD> -U root raw 0x30 0x19

This worked great at the time and I successfully manually set the fan speed to 50% or whatever and things were back to being great.

However, just recently I had some power issues and long story short, now when the nodes are powered on I'm back to getting 100% fan and when I try the raw commands above all I get is:

Unable to send RAW command (channel=0x0 netfn=0x30 lun=0x0 cmd=0x19 rsp=0x81): Unknown (0x81)

I feel like I'm going crazy. This used to work great, I even wrote the code down, but now, nothing!

I think maybe I updated the BMC version to the latest 2.53 but I have no idea if I did it while the command worked or not. Does anyone have any ideas?

Not familiar with that hardware, but I know I get that error if my dedicated IPMI port is not connected. So I would check to make sure you are getting lights on that ipmi port, power surges and all.

Thanks for the reply, I'll definitely check into that, but since this is a blade chassis, as far as I can tell it doesn't have an ipmi port, when I load the BMC page I have it set to 'shared port'. Also, other ipmi commands such as 'sensors' return data successfully, would this imply that things are plugged in correctly?
