Hi, I have 2 separate baremetal boxes, 1 is dell and the other is of lenovo make. I have created 2 separate instanenv.json files for both of them, and tried importing. the dell box was imported earlier and is now part of the cloud and now when i am trying to import the lenovo box it gives me the <uuid of dell> is alredy registered. I am not sure why this is coming when they both have separate ip addresses and even mac. json files: (undercloud) [stack@hkg2director ~]$ cat dcn01/hci3.json { "nodes": [ { "name": "HCI3", "pm_type": "ipmi", "ports": [ { "address": "90:B1:1C:4F:CA:3B", "physical_network": "ctlplane" } ], "cpu": "24", "memory": "114688", "disk": "2602", "arch": "x86_64", "pm_user": "root", "pm_password": "password", "pm_addr": "172.25.180.57", "_comment": "HCI 3" } ] } (undercloud) [stack@hkg2director ~]$ cat dcn02/ceph3.json { "nodes": [ { "name": "ceph3", "pm_type": "ipmi", "ports": [ { "address": "38:68:DD:8D:9E:4A", "physical_network": "ctlplane" } ], "cpu": "48", "memory": "65536", "disk": "558", "arch": "x86_64", "pm_user": "root", "pm_password": "password", "pm_addr": "10.11.11.12", "_comment": "ceph 3" } ] } With regards, Swogat Pradhan
