This document (7007619) is provided subject to the disclaimer at the end of this document.

Environment


SUSE Linux Enterprise Server 11 (HAE)
SUSE Linux Enterprise Server 11 Service Pack 1 (HAE)

Situation

When monitoring a High Availability Cluster with SLES 11 sending updates to a email address about the cluster status can be useful.

  • Changes in resource location
  • Node status / reboots
  • Network outages / communication problems

Resolution

Configure a mail resource that looks like the following XML example. You can add this in the crm_gui (Cluster GUI
or through the crm command line utility.

Adding through the GUI:

To add the mailTo resource open the Pacemaker GUI either through the command crm_gui or in yast2 "Pacemaker GUI".

1) Under resource click add choose clone and then primitive for the resource.
2) Next fill in the information for the name and choose
  • Class -> OCF
  • Provider ->Heartbeat
  • Type ->MailTO
3) Once the resource attributes tab is accessible fill in the email setting with the email address desired.

Apply the changes and the resource should come online.


Adding the resource via the crm interface

HAE1:~/Desktop # crm
crm(live)# configure
crm(live)configure# primitive MailTo ocf:heartbeat:MailTo \
> params email="me@myaddress.com"
crm(live)configure# commit
