Snapshot space reserve
Snapshot reserve
(percent of volume
reserve)
Percentage of the volume reserve allocated for snapshots. The groupwide default is
100 percent of the volume reserve.
Alt+S
Warn when in-use space
reaches this percentage
of snapshot reserve (0–
100
Percentage of the snapshot reserve that, when consumed, results in event
messages and an alarm.
The groupwide default is 90 percent of the snapshot reserve.
For example, if a volume size is 200MB and you reserve 100 percent of the volume
size for snapshots, a warning occurs when the amount of in-use snapshot reserve is
180MB, using the default (90 percent).
Alt+A
Snapshot settings
Set volume oine When creating a snapshot that exceeds the snapshot reserve, this option sets the
volume and snapshots oine.
You can override this setting on a per-volume basis.
Alt+V
Delete oldest snapshot When creating a snapshot that exceeds the snapshot reserve, this option deletes
the oldest snapshots to free sucient snapshot reserve (the groupwide default).
You can override this setting on a per-volume basis.
Alt+D
Borrow snapshot space
as needed
Temporarily increases the available snapshot space for a volume by borrowing from
the snapshot reserve of other volumes and from pool free space.
This option is enabled by default.
You can override this setting on a per-volume basis.
Alt+B
Volume sector size
512 bytes per sector Sets the volume sector size to 512 bytes per sector. The sector size of a volume
does not depend on the sector size of the physical drives in the array. The default
volume setting of 512 bytes is almost always optimal, even if the physical drives use
4K-byte sectors.
Alt+5
4K bytes per sector Sets the volume sector size to 4K bytes per sector. If you create a volume that uses
4K-byte sectors, rst verify that your operating system supports 4K-byte sectors.
Refer to the documentation for your operating system for information about
whether 4K-byte sectors are supported.
Alt+4
NOTE: After you have created a volume, you cannot change its sector size.
Volumes Panel and Folder Information Panel

the volumes in that folder.
Both panels include a View drop-down list from which you can select the way that you want the information to be displayed. The
