Right, follow the Migration link, https://xcat-docs.readthedocs.io/en/stable/advanced/migration/index.html to backup/restore the MN.
xCAT also introduce xcat-inventory to do the source control, you can check here: https://github.com/xcat2/xcat-inventory https://xcat-docs.readthedocs.io/en/latest/advanced/xcat-inventory/index.html This will work. `makedhcp -n` will add this network to the dhcpd.conf. I assume I can set up another network in the networks table, create a virtual interface in the MN with that vlan Thanks, Casandra Qiu ...................................................................

Got a couple of questions, would greatly appreciate if you can help out with all your collective wisdom. question #1 We have xcat version 2.15 MN running on centOS 7.7, and I am looking into backup/restore of the setup. Currently I am only using /opt/xcat/sbin/dumpxCATdb to backup the database. I also backup the /install directory of the system. If there anything else I should be backing up in the system? How about /tftpboot , all the DNS information? In case of a total system failure ( of the MN ) , I am thinking about how to bring the system back to its original working state. Also, what is the recommended method of restoring a system like this? I would guess - a. build the OS b. install base xcat rpms c. restore DB backup d. may be restore /tftpboot e. restore /install directory ? question #2 So, we currently have a single network defined to build systems in the MN. I need to be able to build systems from another network. How does one get to do this? I assume I can set up another network in the networks table, create a virtual interface in the MN with that vlan, assign a DHCP scope and do makedhcp? Would that work? Or do I need to do anything else? Any help/reference/guidance is very helpful and appreciated. thanks --imam toufique _______________________________________________ xCAT-user mailing list xCAT-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/xcat-user _______________________________________________ xCAT-user mailing list xCAT-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/xcat-user
