LUNs tab

A LUN (logical unit) is the block storage element made available by an array or filer to a server.

Alarm Summary. Displays alarms on LUNs, disks. To investigate further, click an alarm. See Assessing Storage Alarms.

Disks tab

Alarm Summary. Displays alarms on disks. To investigate further, click an alarm. See Assessing Storage Alarms.

Advanced Find

The tabs for specific entities (like LUNs, Disks, Pools, NASVolumes) quickly identify the Top 15 objects exhibiting the “worst” values for a particular metric. Often, however, there is a need to locate objects by name, or with other characteristics. Use the Advanced Find functionality to locate these items.

Queries can be constructed using a combination of Property conditions and Metric conditions.

Figure 16. Advanced Find
Click Perform Query.

To find entities with current status or physical state:

Click Perform Query.
Figure 17. Query Conditions

The metric conditions area lets you easily construct a more complex query that can include up to 3 conditions on metrics.

Period. Refers to the time range on the zonar displayed in the upper right-hand corner. Select the time the query should use for the metric values. When n/a is selected, this condition is ignored.
Metric. This drop down shows the metrics available for this entity type for this vendor.
Click the + icon if you want to add another condition. The next condition row will be preceded by a AND/OR selector. A trash can icon will appear to the right of the + icon to let you remove a condition.
