5.2 Review Release Notes

Before starting the upgrade, review the Release Notes for the SDS 9.0.x release to understand the functional differences (if any) and possible impacts to the upgrade. When upgrading SDS to the target release, the following alarms may be reported on the GUI during the period when the primary SDS site NE is at the new software level and the DR SDS site NE is at the old software level:

• 31124: A DB replication audit command detected errors
• 31105: The DB merge process (inetmerge) is impaired by a s/w fault
• 31232: High availability server has not received a message on specified path within the configured interval
• 31283: Lost Communication with server (cmha)
• 31109: Topology Config Error (cmha)

These alarms, if present, exist for the active and standby DR SDS site servers. They should clear automatically within five minutes, and cease to be raised once the DR provisioning site NE is upgraded to the same software level as the primary SDS site. To avoid seeing these alarms altogether, the upgrade of the primary SDS Site and DR SDS site NEs should be performed within the same maintenance window.
