Link Services Command Reject
The code returned by a recipient device (such as a cartridge subsystem) receiving a
request for Extended Link Services which are unsupported. The recipient returns a
reason code of “Command not supported.”
Linking
(1) The activity of connecting one inbound fiber and one outbound fiber to a port. (2)
The activity of linking commands, as identified in the INquiry data, where the flag
bit of the Command Descriptor Block is set to zero.
LIP
See Loop initialization primitive.
LIRP
Loop Initialization Report.
LIS_HOLD_TIME
Loop Initialization Sequence Hold time.
LISM
Loop Initialization Select Master.
Login
The FC-required process used by any initiating N_Port or NL_Port in an FC fabric to
sign in with any other receiving N_Port or NL_Port port with which it plans to
communicate. The signing in process provides the initiator with critical information
about the attributes of the recipient port before it attempts to make a connection with
it.
Login_BB_Credit
On an Arbitrated Loop, this signal is the value equal to the number of receive buffers
that a recipient NL_Port guarantees to have available once a loop circuit is
established. Login_BB_Credit is communicated via the FLOGI, PLOGI, or PDISC
Extended Link Services.
Logout
An Extended Link Services command that terminates all open Exchanges with the
SCSI initiator and its target. LOGO is invokable when originated by the initiator,
requires a response by the drive, required when originated by the drive, and requires
a response by the initiator.
LOGO
See Logout.
Loop initialization primitive
Assigns up to a possible 127 addresses to different ports on the loop and builds a
map of these addresses.
LPSM
Loop port state machine.
LRC
Longitudinal redundancy check.
LSB
Least Significant Bit.
LS_RJT
See Link Services Command Reject.
