Rename a Subcloud¶
You can rename an existing subcloud using the CLI or Horizon.
Prerequisites
In order to rename a partucular subcloud, the subcloud must be in the unmanaged mode and the deployment status must be either complete or prestage-complete. Otherwise, you will get the following error message:
The server could not comply with the request since it is either malformed or otherwise incorrect. Subcloud subcloud1 must be unmanaged and in a valid deploy state for the subcloud rename operation.
ERROR (app) Unable to update subcloud subcloud1
Rename a Subcloud Using CLI¶
To rename a subcloud, you can run the dcmanager subcloud update <old-subcloud-name> --name <new-subcloud-name> command.
Example:
~(keystone_admin)]$ dcmanager subcloud update subcloud1 --name amea
+-----------------------------+----------------------------------------------------------+
| Field | Value |
+-----------------------------+----------------------------------------------------------+
| id | 1 |
| name | amea |

| location | VBOX workstation: workstation_central address: 127.0.0.1 |

Renaming a subcloud while rehoming¶
It may be required to change the name of a subcloud during the rehoming process. For example, if you are rehoming an existing subcloud whose region name is the same as the subcloud name, the dcmanager will try to query the region name as long as the subcloud is operational for the rehoming process. The dcmanager then uses the name of the queried region to create it on the destination DC. If the region name already exists on the destination DC, the dcmanager will throw an error.
To avoid this scenario, you can rename a subcloud while rehoming by using the following command:
~(keystone_admin)]$ dcmanager subcloud add --migrate --name [NEW_SUBCLOUD_NAME] --bootstrap-address [BOOTSTRAP_ADDR] --bootstrap-values [BOOTSTRAP_VALUES] --deploy-config [DEPLOY_CONFIG] --install-values [INSTALL_VALUES]
+-----------------------------+----------------------------------------------------------+
| Field | Value |
+-----------------------------+----------------------------------------------------------+
| id | 1 |
| name | [NEW_SUBCLOUD_NAME] |
| description | VBOX DC 1 subcloud 1 |
| location | VBOX workstation: workstation_central address: 127.0.0.1 |
| software_version | 23.09 |
| management | unmanaged |
| availability | offline |
| deploy_status | not-deployed |
| management_subnet | 192.168.1.0/26 |
| management_start_ip | 192.168.1.2 |
| management_end_ip | 192.168.1.50 |
| management_gateway_ip | 192.168.1.1 |
| systemcontroller_gateway_ip | 192.168.0.1 |
| group_id | 1 |
| created_at | 2023-06-08 07:10:05.026072 |
| updated_at | None |
| backup_status | None |
| backup_datetime | None |

Show subcloud detailed information¶
To determine the region name of a given subcloud, you can run the following command:
~(keystone_admin)]$ dcmanager subcloud show subcloud1 --detail
+-----------------------------+----------------------------------------------------------+
| Field | Value |
+-----------------------------+----------------------------------------------------------+
| id | 1 |
| name | subcloud1 |

Rename a Subcloud Using Horizon¶
You can rename a subcloud from the System Controller.
Procedure
From the System Controller, go to the subcloud list.
From the list of subclouds, go to the Actions menu of the subcloud whose name you want to change and select Edit Subcloud.
In the Edit Subcloud page, change the name of the subcloud in the Name field and click Submit.
Postrequisites
Remember to return the subcloud to managed after renaming the subcloud so that the subcloud is actively monitored and in sync.
Note
After renaming a subcloud, the alarms of the subcloud will be cleared and the system will generate new alarms using the new subcloud name.
All the files (ansible files, logs files) linked to the subcloud name will also be renamed if the subcloud is renamed.
If a subcloud is renamed, the logs will show the new name of the subcloud.
For the subclouds whose region name is same as subcloud name, the region name would remain same as used at the time of bootstrapping.
Errors and Exceptions¶
You may encounter the following error scenarios while attempting to rename a subcloud:
Error while trying to rename a subcloud with the same name as the existing subcloud you are trying to rename.
Provided subcloud name SUBCLOUD_NAME is the same as the current subcloud SUBCLOUD_NAME. A different name is required to rename the subcloud
Error while trying to rename a subcloud with the name of other existing subcloud
Subcloud with name or region name SUCLOUD_NAME already exist.
Error while trying to rename a subcloud with a non-standard naming convention
new name must contain alphabetic characters
Error while trying to create a subcloud using the
--nameoptionThe --name option can only be used with --migrate option.

--nameparameter with a value different from the subcloud name defined in the bootstrap filesubcloud name does not match the name defined in bootstrap file
