Examples with ZoneInfo com.emc.storageos.db.client.model.ZoneInfo used on opensource projects

Example 11 with ZoneInfo

use of com.emc.storageos.db.client.model.ZoneInfo in project coprhd-controller by CoprHD.

the class NetworkDeviceController method fetchInitiatorsInNetworkZoneInfoMap.

/**
 * For the given network and initiators, which are in the network,
 * and a given list of storage ports, find all the zones on the network
 * system for the initiators. Search the zones to find ones that have
 * one or more of the ports and create the zoning map between the
 * initiators and ports. Returns the results as {@link ZoneInfoMap} which is map
 * of initiator port WWN and storage port WWN keyed by zone-key, where zone-key
 * is the concatenation of the initiator port WWN and the storage port WWN.
 * <p>
 * Note that the map returned contains only the zones that were selected for use by ViPR. In the case of duplicate zones between an
 * initiator-port pair, ViPR applies a selection criteria to choose one. See {@link #selectZonesForInitiatorsAndPorts}
 * <p>
 * Note that a zone in the network system can have more than one initiator and one storage port. For such zone, there can be multiple
 * entries in the map, one for each initiator/port pairs.
 * <p>
 * If the initiator is not in a network or no zones could be found for the initiator, there will be no entries for this initiator in the
 * map. An empty map will be returned if no zones could be found for any initiator.
 *
 * @param network the network of the initiators
 * @param map an OUT parameter where ZoneInfoMap is stored
 * @param initiators the initiators for which the zones will be read
 * @param initiatorPortsMap the storage ports of interest in the networks.
 * @return the network system used to read the zones
