Dell MD3600I, MD3620I owner manual 155

NOTE: Before you create a new snapshot of a source virtual disk, stop any data access (I/O) activity or suspend data transfer to the source virtual disk to ensure that you capture an accurate snapshot of the source virtual disk. Close all applications, including Windows Internet Explorer, to make sure all I/O activity has stopped.

NOTE: Removing the drive letter of the associated virtual disk(s) in Windows or unmounting the virtual drive in Linux helps to guarantee a stable copy of the drive for the Snapshot.

Before creating a snapshot virtual disk, the host server has to be in the proper state. To ensure that the host server is properly prepared to create a snapshot virtual disk, you can either use an application to carry out this task, or you can perform the following steps:

1Stop all I/O activity to the source.

2In the AMW, select the Logical tab and select a valid source virtual disk.

3Select Virtual Disk→ Snapshot→ Create. Alternatively, you can right- click the source virtual disk and select Create Snapshot Virtual Disk from the pop-up menu.

The Create Snapshot Virtual Disk Wizard - Introduction dialog appears.

4Select Simple (Recommended), and click Next. The Specify Names window is displayed.

5Enter the Snapshot virtual disk name and the Snapshot repository virtual disk name and click Next.

The Specify Snapshot Repository Capacity window is displayed.

6Enter the snapshot repository virtual disks capacity as a percentage of the source virtual disks capacity and click Next.

The Preview window containing the summary of the snapshot virtual disk is displayed.

7Click Finish.

The Completed window is displayed.

8Click OK.

After creating one or more snapshot virtual disks, mount the source virtual disk, and restart the host application using that source virtual disk.
