\r\n\r\nI have an interesting issue that I am running into with some old SuperMicro Servers.  I have got a few old SuperMicro servers where system serial number is set to 1234567890 ( fun ... , isn't it? :-) ) .\r\n\r\nwhen xcat does discovery with more than 1 of those node types, I can see that MTMS is got the same serial number ( 1234567890) for of those nodes and xnba gets all confused and discovery never completes.  \r\n\r\nI am on 2.13.11 release: \r\n\r\n[root@services-xcat ~]# lsxcatd -a\r\nVersion 2.13.11 (git commit 6b51474e72575f0432973016d2114f07083e9356, built Tue Mar 13 07:45:52 EDT 2018)\r\nThis is a Management Node\r\ndbengine=SQLite\r\n\r\nIs this a known issue?  I saw an issue posted similar to this.  Is there something I could do to avoid this?  I have looked into modify serial number through the BIOS, but it is not trivial, and I was actually not successful doing that.  \r\n\r\nthanks."},"comment":{"url":"https://api.github.com/repos/xcat2/xcat-core/issues/comments/407640695","html_url":"https://github.com/xcat2/xcat-core/issues/5428#issuecomment-407640695","issue_url":"https://api.github.com/repos/xcat2/xcat-core/issues/5428","id":407640695,"node_id":"MDEyOklzc3VlQ29tbWVudDQwNzY0MDY5NQ==","user":{"login":"techie879","id":24217971,"node_id":"MDQ6VXNlcjI0MjE3OTcx","avatar_url":"https://avatars1.githubusercontent.com/u/24217971?v=4","gravatar_id":"","url":"https://api.github.com/users/techie879","html_url":"https://github.com/techie879","followers_url":"https://api.github.com/users/techie879/followers","following_url":"https://api.github.com/users/techie879/following{/other_user}","gists_url":"https://api.github.com/users/techie879/gists{/gist_id}","starred_url":"https://api.github.com/users/techie879/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/techie879/subscriptions","organizations_url":"https://api.github.com/users/techie879/orgs","repos_url":"https://api.github.com/users/techie879/repos","events_url":"https://api.github.com/users/techie879/events{/privacy}","received_events_url":"https://api.github.com/users/techie879/received_events","type":"User","site_admin":false},"created_at":"2018-07-25T05:47:51Z","updated_at":"2018-07-25T05:47:51Z","author_association":"NONE","body":"haa haa, thanks for mentioning that, but it is not an option for us.  we don't image that many nodes and switch based discovery are not a practical solution for us.  This is could all be easier if xcat had a MAC address based discovery, but my request was rejected before about that.  I did not understand the rationale why it could not be added as an option.  \r\n\r\nIf you have a trick to do discover based on ONLY uuid , that might help too.  "}}
