Re: [xcat-user] How to re-discover a node?

Hi Rich,

Are you tracing the latest xCAT releases? or locked on an earlier xCAT release?

Great to hear that you are managing so many kinds of x86 servers with xCAT. This information is quite important for us.

Due to resource limitation, we cannot perform sufficient verification on non-Lenovo x86 servers. We expect the community can provide some information and feedback, raise some feature request and even contribute some PRs on this.

If you expect any new feature or find any issue during your usage of xCAT on x86 servers, please feel free to open ticket on guithub(https://github.com/xcat2/xcat-core). If you already have some workaround code on this, any PR is appreciated.

thanks

Hi Yang

You're really surprised about xCAT customers managing Dell servers? ;-)
We've been using xCAT for roughly 15 years on Sun,Dell,HP,HPE,Lenovo,IBM,EXXACT,
SuperMicro - at last count we had over 30 different vendor/machine type
combinations. We did start using xCAT when it was a proprietary IBM product
(our first IBM cluster was a Pentium III cluster) and really glad it
went open source ;-)
