Configuring space reservation monitoring

You can monitor the fractional space reserved for LUNs on a storage system volume.

Considerations

SnapDrive for Windows enables you to monitor fractional space reserved for LUNs on a storage system volume. To monitor the fractional space reserved on your storage system from your Windows host, SnapDrive lets you perform the following tasks:

Set fractional space reservation thresholds for volumes containing LUNs
Set rate-of-change percentage between two Snapshot copies or between a Snapshot copy and the active file system of the storage system volume
Monitor space that can be reclaimed by deleting a Snapshot copy
Set monitor polling interval
Enable and disable e-mail notification

For more information about fractional space reservations, see the Data ONTAP Block Access Management Guide.

Steps

Under SnapDrive in the left MMC pane, select the instance of SnapDrive you want to manage. Then, select Disks.
From the menu choices at the top of MMC, navigate to Action > Properties.
In the Disks Properties window, select the Space Reservation Monitor tab.
In the Space Reservation Monitor panel, perform the following actions:
