Solution 2390100.1 : Private Cloud Appliance: After running the CLI 'deprovision compute-node' command, the node fails to reprovision.

Applies to:

Private Cloud Appliance X6-2 Server Upgrade - Version All Versions and later
Oracle Virtual Compute Appliance X4-2 Hardware - Version All Versions and later
Oracle Virtual Compute Appliance X3-2 Hardware - Version All Versions and later
Private Cloud Appliance X5-2 Hardware - Version All Versions and later
Information in this document applies to any platform.

Goal

PCA 2.3.2 added a new Deprovisioning command.

See:
Oracle® Private Cloud Appliance Administrator's Guide for Release 2.3
8.19 Deprovisioning and Replacing a Compute Node

If you followed that process for any reason, and now find the node will not provision, an additional step may have been missed.

Solution

Make sure you changed the ILOM password back to default as noted here:
Oracle® Private Cloud Appliance Administrator's Guide for Release 2.3
4.2.15 deprovision compute-node

If this is not done, the node will fail to reprovision and it will have a temporary IP address in the 192.168.4.190 to 192.168.4.199 range.

Deprovisioning ensures that all configuration entries for a compute node are removed cleanly, so that no conflicts are introduced when a replacement compute node is installed.

If the same node is reprovisioned back into the same rack, the software will treat it as a new node. The PCA software expects new nodes to have the default password of Welcome1.

If you ssh into the ILOM and change the default password, the provisioning should continue. The first thing you should notice is the ssh connect is terminated because the node will complete post discovery. It will have an IP in the fixed IP address range.
