Example 1 with ExportPathsServiceOption

use of com.emc.storageos.storagedriver.storagecapabilities.ExportPathsServiceOption in project coprhd-controller by CoprHD.

the class DellSCProvisioning method exportVolumesToInitiators.

/**
 * Export volumes to initiators through a given set of ports. If ports are
 * not provided, use port requirements from ExportPathsServiceOption
 * storage capability.
 *
 * @param initiators The initiators to export to.
 * @param volumes The volumes to export.
 * @param volumeToHLUMap Map of volume nativeID to requested HLU. HLU
 *            value of -1 means that HLU is not defined and will
 *            be assigned by array.
 * @param recommendedPorts List of storage ports recommended for the export.
 *            Optional.
 * @param availablePorts List of ports available for the export.
 * @param capabilities The storage capabilities.
 * @param usedRecommendedPorts True if driver used recommended and only
 *            recommended ports for the export, false
 *            otherwise.
 * @param selectedPorts Ports selected for the export (if recommended ports
 *            have not been used).
 * @return The export task.
 * @throws DellSCDriverException
