The Thin Provisioning Pool monitor window monitors the threshold values for Thin Provisioning Pool capacity usage.
When a device is selected from the tree in the Thin Provisioning Pool monitor window, the values of the "Caution threshold value" and the "Warning threshold value" set for each Thin Provisioning Pool and the Threshold monitoring status are displayed in a table. The "Caution threshold value" and the "Warning threshold value" are prepared at the disk storage system, and are the threshold values for Thin Provisioning Pool capacity usage. The Thin Provisioning Pool Threshold monitoring status depends on the capacity used, as displayed in the table below. The icons indicating the Threshold monitoring status are displayed in the tree and in the TPP part of the table.
Threshold monitoring status | Icon | Explanation of status |
|---|---|---|
Normal | None | The Thin Provisioning Pool capacity used is less than the "Caution threshold value". |
Caution |
| The Thin Provisioning Pool capacity used is less than the "Warning threshold value" and greater than or equal to the "Caution threshold value". |
Warning |
| The Thin Provisioning Pool capacity used is greater than or equal to the "Warning threshold value". |

The information displayed in the Thin Provisioning Pool monitor window was current at the time it was fetched from the disk storage system. To refresh information, in the Thin Provisioning Pool monitor window, select [View] - [Refresh].
See
For details on the Thin Provisioning Pool monitor window, refer to "B.11.1 Thin Provisioning Pool monitor window".
The initial values for the "Caution threshold value" and the "Warning threshold value" are set by the disk storage system when a Thin Provisioning Pool is created. If required, change the settings for the capacity threshold values.
In the Resource management window menu, select [File] - [Thin Provisioning Pool monitor window].
In the tree of started Thin Provisioning Pool monitor window, select the device where the Thin Provisioning Pool is registered, then in the table, select the Thin Provisioning Pool (multiple Thin Provisioning Pool can be selected - in this case all selected Thin Provisioning Pool will have the same threshold value).
Start the dialog box for changing the notification threshold values in one of the following ways:
In the Thin Provisioning Pool monitor window menu, select [Operation] - [Change threshold amount].
In the Thin Provisioning Pool monitor window, click <Change threshold amount> button.
In the dialog box, enter values at "Warning (%)" and "Caution (%)", then click <OK>. The value can be selected by selecting the [Both], [Warning only], or the [Caution only] button.
See
For details on the dialog box for changing notification threshold values, refer to "B.11.5 Dialog for changing notification threshold values".
If threshold values are exceeded, then follow the procedures below:
Detection of status change
When a threshold value is exceeded, the product receives an SNMP Trap that notifies it of the change in Thin Provisioning Pool status at the disk storage system, and displays the status change in the event log.
In addition, the "T" mark on the icon in the Resource management window for the disk storage system changes to the color that indicates the Thin Provisioning Pool status.
Refreshing
Check the event display and then select [View] - [Refresh] in the Resource management window to obtain the latest information from the device. If the Thin Provisioning Pool monitor window is open, then select [View] - [Refresh] in the Thin Provisioning Pool monitor window.
Checking the status from the Thin Provisioning Pool monitor window
Start the Thin Provisioning Pool monitor window and check the Thin Provisioning Pool status. Extend disks or take other action in accordance with the exceeded threshold values.
See
If the SNMP Trap that notifies of changes in the Thin Provisioning Pool status is not received due to packet loss or other reason, then the product detects the change by polling the Thin Provisioning Pool information of the disk storage system. Since the polling interval is one hour, the time from status change to detection is within one hour. The polling intervals can be customized. For details, refer to “C.13 Polling Service Setting File”.
Note
When a Thin Provisioning Pool is selected from the tree on the Thin Provisioning Pool monitor window, the screen displays the values set for the "Caution threshold value" for each logical volume and the Threshold monitoring status. The threshold values are provided at the disk storage system and relate to the logical volume capacity that is not yet allocated. The logical volume Threshold monitoring states depend on the capacity not yet allocated, as shown below. Icons indicating the Threshold monitoring status are displayed for the logical volumes in the table.
Threshold monitoring status | Icon | Explanation of status |
|---|---|---|
Normal | None | The unallocated capacity of the logical volume is less than the "Caution threshold value". |
Caution |
| The unallocated capacity of the logical volume is greater than or equal to the "Caution threshold value". |
Changes in the Threshold monitoring status of logical volumes do not affect the color of the "T" mark on disk storage system icons in the Resource management window.
This product does not display an event when logical volume threshold values are exceeded.
This product cannot set logical volume threshold values.
