DCB fails on newly provisioned nodes

Description

To repro:

Provision a fresh node with metadata dcb:username, dcb:password, and dcb:script-file, e.g.:

<node foreign-id="1658852690938" node-label="test-switch-cisco"> <interface ip-addr="192.168.1.231" status="1" snmp-primary="P"> <monitored-service service-name="DeviceConfig"/> </interface> <meta-data context="requisition" key="dcb:username" value="${scv:test-switch:username}"/> <meta-data context="requisition" key="dcb:password" value="${scv:test-switch:password}"/> <meta-data context="requisition" key="dcb:script-file" value="cisco-ios-startup"/> <meta-data context="requisition" key="dcb:retention-period" value="1w"/> <meta-data context="requisition" key="dcb:schedule" value="0 0 1 * * ?"/> </node>

Sync the requisition, wait for the node to be available / wait for the uei.opennms.org/internal/provisiond/nodeScanCompleted event; then

Try to run dcb-trigger (or, for that matter, dcb-get) via Karaf shell:

admin@opennms()> opennms:dcb-trigger -v 192.168.1.231 Error executing command: java.lang.IllegalArgumentException

Karaf.log contains:

However, if OpenNMS is restarted, this will work immediately. It would be super awesome if we didn't have to restart OpenNMS after provisioning a node we intent to use with DCB.

The resolution was to use a single Pollar for retrieving all nodes.

Edited

Also it doesn't work from WebUI with the error: Unable to trigger config backup for 192.168.68.110 at location Default with configType DeviceConfig

 

Node added through Requisition page.

Pulling in for eng uptake since the workaround is quite an unpleasant one.

I suspect this only affects the Karaf shell commands - if these were triggered by the poller they would go through.
