Upgrades can only be performed while no requests are in progress or queued. The upgrade process verifies that no requests are in progress before starting the upgrade. However, for queued requests no such check is performed. You must check if there are any queued requests before starting the upgrade as described below. If you update N1 Provisioning Server software without deleting the queued and queued-blocked requests from the system, some of these requests may appear as failed or in error after the upgrade. You can delete the failed requests or choose to ignore them. For each request that was deleted before the upgrade or which appears as failed after the upgrade, you must reissue the request from the control center.
Login in as root (su - root) on the control plane server.
List queued and queued-blocked requests.
Type opt/terraspring/sbin/request -l to list all queued and in-progress requests.
Delete queued and queued-blocked requests.
If there are any queued or queued-blocked requests. type the command /opt/terraspring/sbin/request -d request_id where request_id is the ID of the request. This must be done for each request listed by the request -l command.
