Can I create a snapshot with the Simple path or the Advanced path?

You can create with the simple path or the advanced path.

About the Simple Path

Use the simple path to let the MD Storage Manager Software configure the snapshot virtual disk and the . When you use the simple path option, you need to set these options:

• Snapshot Virtual Disk Name – Use a name that associates the snapshot virtual disk to the corresponding snapshot repository virtual disk and to the .
• Snapshot Repository Virtual Disk Name – Use a name that associates the snapshot repository virtual disk to the corresponding snapshot virtual disk and to the source virtual disk.
• – Map the snapshot virtual disk to a host. You can choose to create the host-to-virtual disk mapping now or at a different time.

About the Advanced Path

Use the advanced path to set a or an on which to put the snapshot repository virtual disk. You can also use the advanced path to change the parameters of the snapshot repository virtual disk. You can use the advanced path regardless of whether or is set. You can set these options when you use the advanced path:

• Select Capacity Type – You can decide where to physically create the snapshot repository virtual disk. You can use one of these capacity options to create the snapshot repository virtual disk.
  • Use free capacity on the same on which the source virtual disk resides.
  • Use free capacity on another disk group.
  • Use unconfigured capacity to make a new disk group for the snapshot repository virtual disk.

  The recommended practice is to put the snapshot repository virtual disk within the disk group where the source virtual disk resides. If you move physical disks related to the disk group to another storage array, all of the virtual disks related to the snapshot virtual disk are together in the same group.

• Snapshot Repository Virtual Disk Capacity – You can set the capacity of the snapshot repository virtual disk. The capacity is set as a percentage of the capacity of the source virtual disk.The default level is set to 20% of the source virtual disk. If a snapshot is active for a longer time, the repository’s capacity must be larger as well.
• Snapshot Repository Virtual Disk Full Policies – You can define when you would like to be notified that the snapshot repository virtual disk is becoming full. Notification is sent after the snapshot repository virtual disk contains a specific amount of data. The amount of data is defined as a percentage of the size of the snapshot repository virtual disk. When the snapshot repository virtual disk reaches this level, the event is logged in the . The default level is set to 50 percent of the source virtual disk. You can set these availability options for the snapshot repository virtual disk and for the source virtual disk.
  • Fail the snapshot virtual disk and keep the source virtual disk available for writes
  • Fail writes to the source virtual disk and keep the snapshot virtual disk available. Hosts cannot send any new data to the source virtual disk.
• Host-to-Virtual Disk Mapping – You can map the snapshot virtual disk to a host and assign a . You can choose to create the host-to-virtual disk mapping now or at a different time.
