@Martin if needed I can raise a RFE for this. Just point me where to do, and I will do it. Thank you.

The host machine is an OpenPOWER AC922 (ppc64le). The BMC basically is an “ipmilan” device but the ciphers must be defined as 3 or 17 by default: [root@h01 ~]# ipmitool -I lanplus -H 10.20.10.2 root -P 0penBmc -L operator -C 3 channel getciphers ipmi ID IANA Auth Alg Integrity Alg Confidentiality Alg 3 N/A hmac_sha1 hmac_sha1_96 aes_cbc_128 17 N/A hmac_sha256 sha256_128 aes_cbc_128 The default ipmilan connector forces the option cipher=1 which breaks the communication. Hi, have you tried to overwrite the default by adding cipher=3 into Options field when adding/updating fence agent configuration for specific host? Eli, looking at https://www.intel.com/content/dam/www/public/us/en/documents/product-briefs/... I'm not sure our defaults make sense, because by default we enable IPMIv2 (lanplus=1), but we set IPMIv1 cipher support (cipher=1). Or am I missing something? Yes I’m running this way right now: ipmilan with cipher=17 on options. But to figure it out I took almost a month. Really. I’ve sent a message on 5 June to the list: Power Management on IBM AC922 Power9 (ppc64le); and I was trying to solve it since them. This was mainly due to poor documentation. I only figured it out when I done a lot of searches on Github to read the oVirt code. So the cipher=1 thing show up, and I guessed that it may be it. And it was… I know that no one cares for ppc64le haha. But I think a change on the list of supported fenceTypes will save some people the time I’ve lost with this. If there’s something like “openbmc" would be great. Or at least a better explanation on the Power Management configure box. Not even the options are explained correctly guessing lanplus=1 was hard. I tried a lot of combinations like: I=lanplus -I lanplus -I=lanplus Thanks, Regards, Martin So I was reading the code and found this “fenceType” class, but I wasn't able to found where to define those classes. So I can create another one called something like openbmc to set cipher=17 by default. Another question is how bad the output is, it only returns a JSON-RPC generic error. But I don’t know how to suggest a fix for this.
