Link Services LIP LIPA LIRP LISA LISM LM_TOV login server Loom loop circuit loop failure Loop_ID loop initialization Loop Mode looplet LPB LPE LPSM LR A protocol for link-related actions. Loop initialization primitive. The signal used to begin initialization in a loop. Indicates either loop failure or node resetting. Loop-initialization previously assigned. The device marks a bit in the bitmap if it did not log in with the fabric in a previous loop initialization. Loop-initialization report position frame. The first frame transmitted in the loop initialization process after all L_Ports have selected an AL_PA. The LIRP gets transmitted around the loop so all L_Ports can report their relative physical position. This is an optional frame. Loop-initialization soft-assigned frame. The fourth frame transmitted in the loop initialization process after a temporary loop master has been selected. L_Ports that have not selected an AL_PA in a LIFA, LIPA, or LIHA frame select their AL_PA here. Loop-initialization select master frame. The first frame transmitted in the initialization process when L_Ports select an AL_PA. LISM is used to select a temporary loop master or the L_Port that will subsequently start transmission of the LIFA, LIPA, LIHA, LISA, LIRP, or LILP frames. Loop master timeout value. The minimum time that the loop master waits for a loop initialization sequence to return. The unit that responds to login requests. The code name given to the second-generation HP Fabric ASIC. This is the ASIC used in the StorageWorks 1 GB switches. A temporary bidirectional communication path established between L_Ports. Loss of signal within a loop for any period of time, or loss of synchronization for longer than the timeout value. A hexadecimal value representing one of the 127 possible AL_PA values in an arbitrated loop. The logical procedure used by an L_Port to discover its environment. Can be used to assign AL_PA addresses, detect loop failure, or reset a node. One of two possible modes for an L_Port, in which the L_Port is in an arbitrated loop, using loop protocol. An L_Port in Loop Mode can also be in Participating Mode or Nonparticipating Mode. A set of devices connected in a loop to a port that is a member of another loop. Loop port bypass. A primitive sequence transmitted by an L_Port to bypass one or all L_Ports to which it is directed. It is used only in arbitrated loops. Loop port enable. A primitive sequence transmitted by an L_Port to enable one or all L_Ports that have been bypassed with the LPB. It is used only in arbitrated loops. Loop Port State Machine. Logic that monitors and performs the tasks required for initialization and access to the loop. It is maintained by an L_Port to track behavior through different phases of loop operations. Alternatively, the logical entity that performs arbitrated-loop protocols and defines the behavior of L_Ports when they require access to an arbitrated loop. Link reset. A primitive sequence used during link initialization between two N_Ports in point-to-point topology or an N_Port and an F_Port in fabric topology. The expected response is an LRR.
