Event alarms to monitor disabling I/O errors

When a dbspace incurs a disabling I/O error, the database server passes the specified values as parameters to your event-alarm executable file.

Event alarm values:

Severity
4 (Emergency)
Class
5
Class message
Dbspace is disabled: 'dbspace-name'
Specific message
Chunk {chunk-number} is being taken OFFLINE.
Event ID
5001

If you want the database server to use event alarms to notify you about disabling I/O errors, write a script that the database server executes when it detects a disabling I/O error. For information about how to set up this executable file that you write, see the appendix on event alarms and the topics on configuration parameters in the HCL Informix® Administrator's Reference.
