Disk Details. Displays the disk’s status, physical details, parent device, and size if available. |
• |
Physical State: Displays the physical state the of disk. It will be marked as "No Information" if the disk does not commit any performance data. To mark disks as "Removed", click on "No Information" link and confirm the disk is removed physically by pressing "Removed" button. |
NOTE: Selecting "No Information Disks" metric from Show Disks With drop down shows the disks with no metrics provided by the Agent. Selecting "Removed Disks" metric from Show Disks With drop down shows the disks manually marked as "Removed" Physical State in No Information Dialog. |
• |
Charts. Displays the following metrics over the time period: |
• |
Pool Details (Arrays only). Displays performance and capacity metrics for the pools to which this disk contributes resources. For more information, see Performance Metrics and Capacity Metrics. To investigate a pool, click its name. For more information, see Investigating a Pool. |
• |
Aggregate Details (Filers only). Lists the aggregates to which this disk contributes resources. For each aggregate, displays its name, status, physical state, and current values for Total Usable Capacity, Available Usable Capacity % Available, Advertised NASVolumes Size, and Overcommitment. To investigate an aggregate, click its name. See Investigating an Aggregate. |
• |
Alarm Summary. Displays alarms on the disk. |

Click the LUNs tab. This tab displays the LUNs carved from this pool. |
• |
Top 5 LUNs. Displays the top five LUNs with the highest average value for Data Rate, and the performance metrics most useful for this array or filer. |
• |
LUN Status Filter. Click to show only LUNs with the selected status in the LUN Details table. |
• |
LUN Details. For each LUN, displays its status, physical state, parent pool or aggregate, and whether the LUN is used by an entity in the monitored environment. The metric columns display current values for Data Rate, Ops Rate, Latency, % Busy, Average Queue Depth, L1 Cache Hit Rate, and Total Advertised LUNs Size. Click a Sparkline to plot metric values over the time period. |
• |

• |
Pool Details. Displays the pool’s status, parent storage array, and current values for IFS Capacity: Free and IFS Capacity Used for the IFS file system. In addition, the total capacity is broken down into hard disk drive and solid state drives metrics as follows: |
• |
Performance. Charts plot the following metrics for the selected pool over the time period: % Busy, Latency, L1 Cache Hit Rate, L2 Cache Hit Rate, Data Read Rate, Data Write Rate, Read Ops Rate, and Write Ops Rate. |
• |
Node Status Filter. Click to show only member nodes with the selected status in the Node Details table. |
• |
Node Details. For each node belonging to the pool, displays its name, status, physical state, and current values for Data Rate, % Busy, Latency, L2 Cache Hit Rate, IFS Capacity, and IFS Capacity: Free. Also displays the worst status of the node’s disks, external network ports, and internal network ports, and identifies the node’s parent pool. Click a Sparkline to plot metric values over the time period. |
