[chef] Re: Re: IPMI / Ohai

Based on this then, I suspect the time this could take is highly variable. Is it bad form to create a hint file from within an ohai plugin? just essentially `echo '{"detected": false}' > /etc/chef/ohai/hints/ipmi.json` or  `echo '{"detected": true}' > /etc/chef/ohai/hints/ipmi.json` after the first detection?

Thank you,

Graham

Hello everyone,

I maintain a deployment of SuperMicro servers, and Dell servers, as well as a compliment of cloud machines. What I want to accomplish is as follows:

An ohai plugin to determine if IPMI is available. I can do this with dmidecode, which takes about 30 seconds:

It only takes less than a second on my hardware:

# time dmidecode --type 38

# dmidecode 2.11

# SMBIOS entry point at 0x000f0440

SMBIOS 2.6 present.

Handle 0x00AD, DMI type 38, 16 bytes
