Snapshot Configuration Properties of the Dell EqualLogic Storage Array

The Snap Configuration tab contains properties that affect the behavior of the storage array in your environment.

Tip: If you don't select the Auto Update Array Host Aliases check box, then you must manually enter any aliases for the array in the Array Host Aliases list. If you specify a list of aliases in the Array Host Aliases property to manually control the names for the array, then clear the Auto Update Array Host Aliases check box. Aliases are important for recognizing an array during snapshot backup jobs. An array can have multiple hostnames, IP addresses, or user configured names, which might be accessible by the client that initiates the snapshot creation.
