Configuration: Premium Feature—Snapshot Virtual Disks 137About the Simple PathUsing the simple path, you can specify:• Snapshot Virtual Disk Name—A user-specified name that helps youassociate the snapshot virtual disk to its corresponding snapshot repositoryvirtual disk and source virtual disk.• Snapshot Repository Virtual Disk Name—A user-specified name thathelps you associate the snapshot repository virtual disk to its correspondingsnapshot virtual disk and source virtual disk.• Snapshot Repository Virtual Disk Capacity—The snapshot repositoryvirtual disk capacity is expressed as a percentage of the source virtual diskcapacity. The maximum percentage allowed is 120 percent.Using the simple path, the following defaults are used for the otherparameters of a snapshot virtual disk:• Capacity Allocation—The snapshot repository virtual disk is created usingfree capacity on the same disk group where the source virtual disk resides.• Host-to-Virtual Disk Mapping—The default setting is Map now.• Percent Full—When the snapshot repository virtual disk reaches thespecified repository full percentage level, the event is logged in the MajorEvent Log (MEL). The default snapshot repository full percentage level is50 percent of the source virtual disk.• Snapshot Repository Virtual Disk Full Conditions—When the snapshotrepository virtual disk becomes full, you are given a choice of failing writeactivity to the source virtual disk or failing the snapshot virtual disk.Preparing Host Servers to Create the Snapshot Using the Simple PathNOTE: Before using the Snapshot Virtual Disks Premium Feature in a Microsoft®Windows® clustered configuration, you must first map the snapshot virtual disk tothe cluster node that owns the source virtual disk. This ensures that the clusternodes correctly recognize the snapshot virtual disk.NOTE: Mapping the snapshot virtual disk to the node that does not own the sourcevirtual disk before the Snapshot enabling process is completed can result in theoperating system mis-identifying the snapshot virtual disk. This, in turn, can result indata loss on the source virtual disk or an inaccessible snapshot.
