This boolean controls whether the disk zoning assignments made by this config definition are retained when the associated service profile is disassociated from its server. Getting this wrong on this specific zoning object means a re-associated server could either unexpectedly keep a previous server's disk-to-controller zoning or lose it and need re-zoning, either of which risks exposing the wrong data to the wrong host. Setting this to true ensures that when this service profile moves to a new blade, its original SAS disk zoning map travels with it instead of being reset.
