Summary

  • This error indicates that the server datastores are not set or not accessible at the moment.

Symptoms:

  • Connection to the server succeeds, but no datastore contents can be accessed
  • yangcli-pro "show session" contains a line indicating the YANG library URI is not found
  • a <get> or <get-config> error fails with a 'wrong config state' error-message



rpc-reply {
  rpc-error {
    error-type protocol
    error-tag operation-failed
    error-severity error
    error-app-tag no-access
    error-message 'wrong config state'
    error-info {
      error-number 302
    }
  }
}





Possible Cause


The server is waiting for subsystem to register for an unknown bundle.

  • If a SIL library is not found by the main server then it will assume that a SIL-SA subsystem will register for this bundle.  The server cannot load the startup config or even the YANG modules because the contents of the bundle are not pre-registered.

  • The server log will contain a line about skipping load_running_config.
    Even though the log says "ready for sessions" the datastores are not active.
    RPC operations that do not access the datastores will continue to function in this mode.

agt: Waiting SIL-SA: skipping load_running_config
ncx: Adding Mod load callback to slot 1
ncx: Adding Mod unload callback to slot 0
netconfd-pro init OK, ready for sessions



Solution


Use the --wait-datastore-ready CLI parameter in the netconfd-pro command line or config file.

This parameter causes the server to reject client sessions unless the datastore is ready.  Use this mode carefully since 



> netconfd-pro --wait-datastore-ready=true --bundle=mybundle



If a client attempts a connection then the SSH or TLS session may be started but the NETCONF session will be closed immediately.  The following example shows a yangcli-pro connection failure:



> run connect

ses: session 3 shut by remote peer
yangcli-pro: Start session failed for user andy on localhost (operation failed)
