The Prefs command displays a list of preferred hosts and their priority levels.

Using the SetPref command, a machine can be specified as a preferred host for a data file, meaning load balancer will attempt to use the Data Vault Agent processes running on that machine before any other to carry out tasks involving the file. A priority level is also set for each preferred host, so if multiple machines are designated as preferred hosts for a particular object, the machines are checked for available Agent processes in the order indicated by the respective priority levels (where a higher priority value means greater priority). If Agent processes on a particular machine have variable priority levels, the highest priority available Agent is used.

By default, the Prefs command displays all preferred hosts. To view only the preferred hosts for a specific compressed data file, include the <file-ID> parameter. File ID values can be determined using the Files command.
