the class ControllerLockingUtil method getHostStorageLockKeys.

/**
 * Returns a list of lock keys for export of Hosts to StorageSystems.
 * This is constructed from a list of Initiators.
 * All the host URIs are collected from the Initiators.
 * If an Initiator does not have a host URI, its hostName is converted to a URI and used.
 * iF export type is Cluster, the clusters are looked up, and all hosts in the
 * cluster are used.
 * The keys are constructed from a concatenation of the host URI and the storage system URI.
 *
 * @param dbClient
 * @param type
 *            ExportGroup.ExportGroupType -- used to determine if cluster export
