OmsaStorageMonitor
With OmsaStorageMonitor you are able to monitor your Dell OpenManaged servers RAID array status. The following OIDS from the STORAGEMANAGEMENT-MIB are supported by this monitor:
virtualDiskRollUpStatus .1.3.6.1.4.1.674.10893.1.20.140.1.1.19 arrayDiskLogicalConnectionVirtualDiskNumber .1.3.6.1.4.1.674.10893.1.20.140.3.1.5 arrayDiskNexusID .1.3.6.1.4.1.674.10893.1.20.130.4.1.26 arrayDiskLogicalConnectionArrayDiskNumber .1.3.6.1.4.1.674.10893.1.20.140.3.1.3 arrayDiskState .1.3.6.1.4.1.674.10893.1.20.130.4.1.4
To test the status of the disk array the virtualDiskRollUpStatus
is used.
If the result of the virtualDiskRollUpStatus
is not 3
the monitors is marked as down.

You’ll need to know the maximum number of possible logical disks you have in your environment. For example: If you have 3 RAID arrays, you need for each logical disk array a service poller. |
To give more detailed information in case of an disk array error, the monitor tries to identify the problem using the other OIDs. This values are used to enrich the error reason in the service down event. The disk array state is resolved to a human readable value by the following status table.

Examples
Some example configuration how to configure the monitor in the 'poller-configuration.xml'.
The RAID array monitor for your first array is configured with virtualDiskNumber = 1
and can look like this:
<service name="OMSA-Disk-Array-1" interval="300000" user-defined="false" status="on">
<parameter key="retry" value="3"/>
<parameter key="timeout" value="6000"/>
<parameter key="virtualDiskNumber" value="1"/>
</service>
<monitor service="OMSA-Disk-Array-1" class-name="org.opennms.netmgt.poller.monitors.OmsaStorageMonitor"/>
If there is more than one RAID array to monitor you need an additional configuration. In this case virtualDiskNumber = 2
. And so on…
<service name="OMSA-Disk-Array-2" interval="300000" user-defined="false" status="on">
<parameter key="retry" value="3"/>
<parameter key="timeout" value="6000"/>
<parameter key="virtualDiskNumber" value="2"/>
</service>
<monitor service="OMSA-Disk-Array-2" class-name="org.opennms.netmgt.poller.monitors.OmsaStorageMonitor"/>
