Registered
The condition that exists for an I_T nexus following the successful completion of a PERSISTENT RESERVE OUT command with a REGISTER ser-
vice action, REGISTER AND IGNORE EXISTING KEY service action, or REGISTER AND MOVE service action and lasting until the registration is
removed.
Registrant
An I_T nexus that is registered.
Right-aligned
A type of field containing ASCII data in which unused bytes are placed at the start of the field (i.e., lowest offset) and are filled with ASCII space
(20h) characters.
Relative port identifier
An identifier for a SCSI port that is unique within a SCSI device. Application clients may use the SCSI Ports VPD page to determine relative port
identifier values.
Relative initiator port identifier
A relative port identifier for a SCSI initiator port.
Relative target port identifier
A relative port identifier for a SCSI target port.
SCSI device
A device that contains one or more SCSI ports that are connected to a service delivery subsystem and supports a SCSI application protocol.
SCSI device name
A name of a SCSI device that is world wide unique within the protocol of a SCSI domain in which the SCSI device has SCSI ports. The SCSI device
name may be made available to other SCSI devices or SCSI ports in protocol specific ways.
SCSI domain
The interconnection of two or more SCSI devices and a service delivery subsystem. A detailed definition of a SCSI Domain may be found in
SAM-5.
SCSI initiator device
A SCSI device containing application clients and SCSI initiator ports that originate device service and task management requests to be pro-
cessed by a SCSI target device and receives device service and task management responses from SCSI target devices.
SCSI initiator port
A SCSI initiator device object acts as the connection between application clients and the service delivery subsystem through which requests
and responses are routed.
SCSI port
A port of a SCSI device that connects the application client, device server or task manager to the service delivery subsystem.
SCSI port identifier
A value by which a SCSI port is referenced within a domain. The SCSI port identifier is either an initiator port identifier or a target port identifier.
SCSI port name
A name of a SCSI port that is world wide unique within the protocol of the SCSI domain of that SCSI port. The name may be made available to
other SCSI devices or SCSI ports in that SCSI domain in protocol specific ways.
SCSI Ports VPD page
A VPD page that allows retrieval of information about all the SCSI ports in a SCSI target device or SCSI target/initiator device.
SCSI target device
A SCSI device containing logical units and SCSI target ports that receives device service and task management requests for processing and
sends device service and task management responses to SCSI initiator devices.
SCSI target port
A SCSI target device object that acts as the connection between device servers and task managers and the service delivery subsystem through
which requests and responses are routed.
SCSI transport protocol standard
A SCSI standard that defines a SCSI transport protocol (e.g., FCP-2, SAS, SRP, or SBP-3).
