The first dialog of the Create Snapshot Virtual Disk Wizard enables you to select either the simple or advanced path to be followed through the wizard.
The simple path (which is recommended) enables you to specify basic
Select this option to specify basic snapshot parameters and accept the common default settings, and click Next when ready to move to the next wizard dialog.
The following are basic snapshot parameters:
|
Snapshot Virtual Disk Name |
Specify a name that helps you associate the snapshot virtual disk to its corresponding repository and |
|
Snapshot Repository Virtual Disk Name |
Specify a name that helps you associate the snapshot repository virtual disk its corresponding snapshot and source virtual disk. |
|
Percent full |
When the snapshot repository virtual disk reaches the specified |
|
Snapshot repository virtual disk full conditions |
Specify the snapshot repository virtual disk's capacity as a percentage of |
The following snapshot parameters are automatically set to these common defaults:
|
Capacity allocation |
The snapshot repository virtual disk is created using |
|
|
The snapshot is given an automatic virtual disk-to-LUN mapping, if Storage Partitioning is not enabled. If this feature is enabled, the default setting is Map Later with Storage Partitioning. |
|
Percent full |
When the snapshot repository virtual disk reaches the specified |
|
Snapshot repository virtual disk full conditions |
If the snapshot repository virtual disk becomes full, the snapshot virtual disk fails. |
Select this option to set the basic snapshot parameters and four advanced snapshot parameters, and click Next when ready to move to the next wizard dialog.
You set the following advanced snapshot parameters:
|
Capacity allocation |
You are given a choice of where to physically place the snapshot repository virtual disk. (You can use free capacity on the same disk group where the source virtual disk resides, use free capacity on another disk group, or use Note: It is better if the snapshot repository virtual disk resides within the disk group where the source virtual disk resides. This location ensures that if physical disks associated with the disk group are moved to another |
|
Virtual Disk-to-LUN mapping |
You are given a choice whether to give the snapshot an automatic virtual disk-to-LUN mapping, or map the snapshot virtual disk later using Storage Partitioning. Note: If Storage Partitioning is not enabled, the default setting is Automatic. If this feature is enabled, the default setting is Map Later with Storage Partitioning. |
|
Percent full |
When the snapshot repository virtual disk reaches the specified threshold percentage, it logs the event, and the icon changes in the Physical/Logical View. The default threshold percentage is set to 50 percent of the source virtual disk. |
|
Snapshot repository virtual disk full conditions |
You are given a choice of failing writes to the source virtual disk or failing the snapshot virtual disk when the snapshot repository virtual disk becomes full. |
