Description

This article explains why an IDP security package download fails on a single node configured for HA.

Symptoms

Suppose, for example, that an administrator wants to download the IDP security package on a node in HA, when the other node is not available (the other node may be out on an RMA, or there is a network or cabling issue). Unfortunately, the administrator is unable to download the IDP security package on the single node. This scenario is played out in the example below, where node 0 is lost. (This example is using Junos OS 12.1X44-D30.)

Solution

When the download command is executed in clustering mode, the primary node tries to open an RCP session to the secondary node. If it cannot do this, the command fails with the error below:

"Done;Failed to copy result file to backup RE, errno: 1"

To download an IDP security package on a single node with a lost cluster member, you must first remove the cluster configuration until the other node is online. Then, when the other node is online, the cluster configuration can be re-added.
