Note that the ipmitool equivalent should be at least lanplus nowadays.

Biggest risk I could see is that some firmware nowadays requires at least 
cipher suite 17, if ipmi is enabled at all.

Implement HMAC-SHA256 in xCAT IPMI ·

This will be compatible with some current implementations that do not have 
SHA-1. HMAC-SHA1 may be still secure, but SHA1 in any context *looks* bad even 
if it isn't.

That change to IPMI.pm might​ alleviate.  Double check if ipmitool with -C 17 
will work, and if that will work, you may need IPMI.pm to change to support 
SHA256 in the hmac.

xCAT uses raw ipmi commands to do ipmi communication.

You can turn xCAT debug on with "chdef -t site clustersite xcatdebugmode=1" and 
then issue a command, like
"rpower <node> stat" to see all the raw ipmi commands xCAT is sending.

Use "chdef -t site clustersite xcatdebugmode=0" to turn debug off.

Hello collective wisdom,

What IPMI interface does xcat use?
Is it lan or lanplus or open? (As in ipmitool -I ) Is it configurable?

I have a bunch of new Dell servers in the lab that don't seem to communicate 
over lan or lanplus interface, only open and I have trouble provisioning them 
through xcat. I suspect it's because of lanplus not supported/missing from 
these servers.
