Extended Unique Identifier, a 48-bit globally unique identifier (EUI-48)
The IEEE maintains a tutorial describing EUI-48 at http://standards.ieee.or
g/regauth/oui/tutorials/EUI48.html.
Extended Unique Identifier, a 64-bit globally unique identifier (EUI-64)
The IEEE maintains a tutorial describing EUI-64 at http://standards.ieee.org/regauth/oui/tutorials/EUI64.html.
Extent
A fixed set of logical blocks occupying contiguous logical block addresses on a single logical unit.
Faulted I_T nexus
The I_T nexus on which a CHECK CONDITION status was returned that resulted in the establishment of an ACA. The faulted I_T nexus condition
is cleared when the ACA condition is cleared.
Field
A group of one or more contiguous bits, a part of a larger structure such as a CDB or sense data.
Format corrupt
a vendor-specific condition in which the application client may not be able to perform read operations, write operations, or verify operations.
Grown defect list (GLIST)
All defects sent by the application client to the device server.
Hard reset
A condition resulting from the events defined by SAM-5 in which the SCSI device performs the hard reset operations described in SAM-5,
SPC-5, and the applicable command standards.
Host
A SCSI device with the characteristics of a primary computing device, typically a personal computer, workstation, server, minicomputer, main-
frame computer, or auxiliary computing device. A host includes one or more SCSI initiator devices.
IEEE company_id
Synonym for OUI.
I_T nexus
A nexus between a SCSI initiator port and a SCSI target port.
I_T nexus loss
A condition resulting from the events defined by SAM-5 in which the SCSI device performs the I_T nexus loss operations described in SAM-5,
SPC-5, and the applicable command standards.
I_T_L nexus
A nexus between a SCSI initiator port, a SCSI target port, and a logical unit.
I_T_L_Q nexus transaction
The information transferred between SCSI ports in a single data structure with defined boundaries (e.g., an information unit).
Idle power condition
When a device server is capable of responding to all of its supported commands, including media access requests, but commands may take
longer to complete than when in the active power condition.
Implicit head of queue
An optional processing model for specified commands wherein the specified commands may be treated as if they had been received with a
HEAD OF QUEUE task attribute.
Initiator device name
A SCSI device name of a SCSI initiator device or of a SCSI target/initiator device when operating as a SCSI initiator device.
Initiator port
Synonymous with SCSI initiator port.
Initiator port identifier
A value by which a SCSI initiator port is referenced within a SCSI domain.
Initiator port name
A SCSI port name of a SCSI initiator port or of a SCSI target/initiator port when operating as a SCSI initiator port.
Internet protocol domain name
The name of a computer or hierarchy of computers within the domain name system defined by the IETF (see RFC 1035 and RFC 1591). The
Internet Assigned Numbers Authority maintains a list of domain name assignments at http://www.iana.or
g/assignments/domain-names.
