There has been a small bugfix in the Nagios/Monitoring plugin check_equallogic. The 'volumes' check had an error in the logic how to handle the volumes, once the system-volumes were successfully ignored. This could cause that some volumes were not taken in account at the output.
The new version (20120123) has fixed this issue. Please use the newest version from now on. Existing versions should be replaced. Thanks to Laurent Colonges for his patience and for the tests with the new version.
