General ASM/ME Operations
This chapter explains general operations you can perform with ASM/ME, including creating Smart Copies, scheduling Smart
Copy operations, and restoring a volume using a Smart Copy.
For operations specific to supported applications, see the following sections:
● Using ASM/ME with Microsoft Exchange
● Using ASM/ME with SQL Server
● Using ASM/ME with Hyper-V
● Use ASM/ME with Microsoft SharePoint

About Volumes
A volume is a storage object used by an application or file system to store data. The Volumes list node in the tree panel displays
a summary of all the volumes known to ASM/ME, including the drive letters on which they are mounted, their names, and a pie
chart of each volume showing the amount of in-use and free space.
Hover the mouse over the mount point for any volume to display a tool tip explaining the terms Free Space and In-Use
Space. Click on any volume’s pie chart to open the node for that volume.
View Volume Details
This section describes how to view volume details, which includes:
● Volume properties
● Smart Copy properties
● PS Series group information for each volume known to ASM/ME
● Operating system of the host using the volume
For volumes on PS Series groups running firmware version 6.0 or later, the following properties can apply:
● Synchronous Replication—The process of replicating a volume to a another storage pool on the same group. When
synchronous replication is enabled on a volume, the volume properties include the state of synchronous replication (enabled
or disabled) and the state of the replication between the SyncActive and SyncAlternate volumes (in-sync or out-of-sync). In
addition, the Features field displays that the volume supports synchronous replication. If synchronous replication is enabled
for a volume, you cannot create a replica (group-to-group replication). These types of replication are mutually exclusive. See
the Dell EqualLogic Group Manager Administrator’s Guide for more details.
● Snapshot Space Borrowing—This feature enables a volume to borrow from free pool space to create snapshots if the
volume runs out of its own snapshot reserve space. Snapshot space borrowing is enabled by default for all volumes created
on version 6.0 or later (however, snapshot borrowing can be enabled on volumes created before the group was updated to
version 6.0). If snapshot borrowing is enabled but the volume has no snapshot reserve space configured, you cannot create
a Smart Copy. See the Dell EqualLogic Group Manager Administrator’s Guide for more details.
NOTE: Contact your PS Series group administrator if your require this volume to support Smart Copy creation.
