Hi Fernando,

This mgt port is used since at the beginning of installation, written into system inventory and is being used all the time in StarlingX system.

My understanding is that it is less likely StarlingX provides an interface to change it after the system is deployed.

 

Anyway, what’s your motivation to make such a change??

 

regards,

Yong

Subject: [Starlingx-discuss] Looking a command that changes Virtual host node MAC Addr.

 

Hi,

 

** Does anybody know how can I change a MAC Address for a Virtual host node?

 

Let’s supposed I want to change controller-1 MAC Address from my cluster, please check following steps to identify Virtual host Controller-1 MAC Addr:

  1. [wrsroot@controller-0 ~(keystone_admin)]$ system host-list

+----+--------------+-------------+----------------+-------------+--------------+

| id | hostname     | personality | administrative | operational | availability |

+----+--------------+-------------+----------------+-------------+--------------+

| 1  | controller-0 | controller  | unlocked       | enabled     | degraded     |

| 2  | compute-0    | compute     | locked         | disabled    | offline      |

| 3  | compute-1    | compute     | locked         | disabled    | offline      |

| 4  | controller-1 | controller  | locked         | disabled    | offline      |

| 5  | storage-0    | storage     | locked         | disabled    | offline      |

| 6  | storage-1    | storage     | unlocked       | disabled    | offline      |

  1. Display host show “mgmt_mac” attribute from controller-1

[wrsroot@controller-0 ~(keystone_admin)]$ system host-show controller-1

** Is there a way to change the “mgmt_mac = 52:54:00:2b:56:bf”?
