Changing the Storage Alert Threshold
The Low Space Threshold is that percentage of available storage below which the system
alerts you to add more disks. By default, the Storage Alert Threshold is set at 10% of
available storage.
Storage Center allocates disk space from a disk folder for volume and replay use as needed
based upon the configurations and IO patterns of each volume. As the Storage Center
approaches the end of the disk space available within the disk folder, you are notified of the
possibility that you could run out of space. This notification indicates that you are in a Space
Low state. The notification occurs when space available falls below the Storage Alert
Threshold.
 To change the storage alert threshold
1 From an assigned disk folder shortcut menu, select
Properties . (Your assigned disk
folder may have a different name.) The Disk Folder Properties window appears.
Figure 205. Disk Folder Properties
2 In the General window, select a Storage Alert Threshold, from 6% to 15%. If available
storage space falls below this number, an alert is generated to warn you that space is
low.
