Background

When an active database node fails, a reserve node gets activated and replaces the failed node, allowing the database to start up again automatically.

Description

In some rare cases, the activation of the reserve node may fail.
This can be identified by the below message in the EXAoperation log

NOTICE System marked as stopped: Startup call failed: e_not_available

Workaround

Perform the Force Shutdown action on the database to stop the incomplete fail-safety restart. Then restart the affected database manually.

Fix

Activision of the reserve node succeeds, as expected.
