Orchestrated Removal Host Software Deployment

A fully deployed patch release can be removed (or un-deployed) by using the Orchestrated Deployment Host Software Deployment procedure and deploying a previous patch release or the major release.

Note

A fully deployed major release cannot be removed (or un-deployed).

For example, the following shows the current software releases deployed:

~(keystone_admin)]$ software list
 +--------------------------+-------+-----------+
 | Release                  | RR    |   State   |
 +--------------------------+-------+-----------+
 | starlingx-10.0.0         | True  | deployed  |
 | starlingx-10.0.1         | False | deployed  |
 | starlingx-10.0.2         | True  | deployed  |
 | starlingx-10.0.3         | False | deployed  |
 +--------------------------+-------+-----------+

To remove patch releases starlingx-10.0.3 and starlingx-10.0.2, follow the Orchestrated Deployment Host Software Deployment procedure, and deploy (or go back to) the starlingx-10.0.1 software release in step <1.

Note

If parallel apply for storage is used, it will be automatically replaced with the serial apply for --storage-apply-type.

Apply the software orchestration deployment strategy.

On completion of the Orchestrated Deployment Host Software Deployment procedure, run the following command:

~(keystone_admin)]$ software list

| starlingx-10.0.3         | False | available |
+--------------------------+-------+-----------+

If the removed patches are no longer required on the system, you can delete them.

~(keystone_admin)]$ software delete starlingx-10.0.3
starlingx-10.0.3 has been deleted.

~(keystone_admin)]$ software delete starlingx-10.0.2
starlingx-10.0.2 has been deleted.
