Understanding Common Error Handling for ISSU

Problem

Description: You might encounter some problems in the course of an ISSU. This section provides details on how to handle them.

Solution

Any errors encountered during an ISSU result in the creation of log messages, and ISSU continues to function without impact to traffic. If reverting to previous versions is required, the event is either logged or the ISSU is halted, so as not to create any mismatched versions on both nodes of the chassis cluster. Table 1 provides some of the common error conditions and the workarounds for them. The sample messages used in the Table 1 are from the SRX1500 device and are also applicable to all supported SRX Series devices.
