Abstract: Examples include registration with a storage networking repository via a network interface device driver independent of a storage initiator. Some examples include registration with a storage networking repository, provision of a state change registration to the storage network device, and acquisition of login information for storage targets from the storage networking repository, each via a network interface device driver and independent of a storage initiator and a storage protocol driver.

Abstract: Examples disclosed herein relate to identification of an alternate principal member port by a target device in a SAN. In some examples, a target device in a SAN may determine that a principal member port of a target driven peer zone on the target device is likely to fail based on diagnostic information related to the principal member port. The target driven peer zone may be configured in the SAN via the target device. In response to determining, the target device may identify an alternate principal member port on the target device. The target device may perform an action to indicate the alternate principal member port as the principal member port.

Abstract: An example system that includes a storage system controller to control a storage array. The storage system controller is to generate, in response to a logical unit change in the storage array, an in-band state change notification that includes in its payload an application-level-rescan-required notification.

Abstract: According to an example, coordination of adjustments to network frame hold time parameters between network devices in a network is initiated based on a trigger condition. Time data may be obtained from a plurality of network devices in the network, where the time data describes a network frame hold time parameter of each network device in the plurality and a network frame processing time of each network device. A set of affected network devices affected by network back pressure in the network, and a set of non-affected network devices in the plurality not included in the set of affected network devices, may be determined. Based on the time data, a pairing may be determined between a time-available network device from the set of non-affected network devices and a time-needed network devices, from the set of affected network devices, to receive an allocation of time credit from the time-available network device.

Abstract: In some examples, a switch includes a plurality of switch ports, and a processor. The processor is to send, through selected switch ports of the plurality of switch ports, respective requests for port information of device ports of a device connected to the selected switch ports, and receive, from the device responsive to the requests, the port information of the device ports. The processor is to identify, from the device ports of the device in response to the received port information, a failover device port for a first device port of the device, and send, to the device, information of the failover device port for the first device port at the device.

Abstract: A system includes multiple devices in a storage area network (SAN). Each device includes at least one network port, at least one processor, and a management module. The management module is to receive announcements generated by ports included in an announcement group, where the ports are included in the other devices, and where each announcement includes port metadata for a particular port. The management module is also to determine, based on the announcements, a network mapping of the ports and the devices.

Abstract: A system and method for target driven peer-zoning (TDPZ) synchronization can include a principal member device and a switch. The principal member device can include to send an active peer zone list request to a switch. In an example, the principal member device can store a first TDPZ database version number and a first TDPZ zone list. In an example, the switch may send a response based on the active peer zone list request. In an example, the response can include a second TDPZ database version number and a second TDPZ zone list. The principal member device may compare the first TDPZ database version number to the second TDPZ database version number.

Abstract: Examples relate to updating login credentials of an iSCSI client in a Storage Area Network (SAN). In an example, an iSNS server may send a target notification to an iSCSI target device, the target notification including an instruction for the target device to update a target-side record of login credentials for an iSCSI client. iSNS server may receive a first target response message from iSCSI target device. In response, iSNS server may provide updated login credentials for the iSCSI client to the iSCSI target device. iSNS server may receive a second target response message. In response, iSNS server may send a client notification to iSCSI client to update a client-side record of login credentials. iSNS server may receive a first client response message. In response, iSNS server may provide the updated login credentials to the iSCSI client.
