Dell MD3220, MD3200 owner manual Creating the Snapshot Using the Advanced Path, 143

4Follow any additional instructions for your operating system. Failure to follow these additional instructions can create unusable snapshot virtual disks.

NOTE: If your operating system requires additional instructions, you can find those instructions in your operating system documentation.

After your host server has been prepared, see "Creating a Snapshot Virtual Disk Using the Advanced Path" on page 140 to create the snapshot using the advanced path.

If you want to use a snapshot regularly, such as for backups, use the Disable Snapshot and Re-create Snapshot options to reuse the snapshot. Disabling and re-creating snapshots preserves the existing virtual disk-to-host mappings to the snapshot virtual disk.

Creating the Snapshot Using the Advanced Path

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

After first preparing the host server(s) as specified in the preceding procedure, complete the following steps to create a virtual disk snapshot using the advanced path:

1Stop the host application accessing the source virtual disk, and unmount the source virtual disk.

2In the AMW, select the Logical tab, 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 Advanced, and click Next.

The Specify Names window is displayed.

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