Comments
On an HDR or RSS secondary server, the user needs to perform mirror recovery on a newly-added mirror chunk manually. (On SDS secondary servers the process happens automatically.) The need for manual mirror recovery is documented here: http://www-01.ibm.com/support/knowledgecenter/SSGU8G_11.70.0/com .ibm.admin.doc/ids_admin_0940.htm in the section "Informix Servers 11.70.0>Administering>System administration>Administrator's Guide>High availability and scalability>Cluster administration>Performing basic administration tasks>Use and change mirroring of chunks" In order to avoid similar confusion in the future, HDR and RSS servers in future releases of the Informix 11.70 and 12.10 server will raise an alarm with class id 4 and event id 4005 to remind the user to perform mirror recovery. The alarm is described here: http://www-01.ibm.com/support/knowledgecenter/SSGU8G_11.70.0/com .ibm.adref.doc/ids_adr_0676.htm in section "Informix Servers 11.70.0>Administering>System administration>Administrator's Reference>Appendixes>Event Alarms>Event alarm IDs"
