March 27, 2003

Products Affected



BPX 8600

Problem Description

Connections may auto-delete if a user falls back to 9.2 during an upgrade from any 9.2 release to 9.3.


During the course of an upgrade, a reason may arise that requires a fallback to the lower release.

Problem Symptoms

Symptoms include:

  • Network users may lose connectivity to remote resources

  • Voice calls may terminate.

  • The software error log may show 612 or 614 errors. Use dspswlog to check the software log.

The workaround is to turn off hitless rebuild before upgrading software. Use the command cnfnodeparm and set Enable Degraded Mode option to N. The solution is to upgrade software to release 9.2.33 before attempting an upgrade to 9.3 releases.
