Feature Set; Table 5-4 Fc-Al Feature Set - Sun Microsystems storagetek sl500 Reference Manual

FC-AL Features
The library then attempts to Port Login (PLOGI) with the fabric directory server to
register with an RFC-4 request with the name service.
The library now waits for initiators, on either this loop or fabric attached, to
complete a Port Login (PLOGI), to complete a Process Login (PRLI), and then to
start executing tape commands.

Feature Set

Sun StorageTek libraries implement the following FC-AL feature set:

TABLE 5-4 FC-AL Feature Set

Feature
Attempt to acquire Hard Address during LIHA
sequence of loop initialization following loss of
power, power-on reset, or recognition of LIP
(AL_PD or AL_PS)
LILP/LIRP:
Loop Master can originate
Non-loop Master L_Ports accept
Login_BB_Credit:
Advertise Login_BB_Credit = 0
Advertise Login_BB_Credit > 0
Accept Login_BB_Credit = 0
Accept Login_BB_Credit > 0
LPEyx/LPByx/LPEfx (origination)
MRKtx (origination)
Open Full Duplex - OPN(yx):
Open Originator can send
Open Recipient accepts
Open Half Duplex - OPN(yy):
Open Originator can send
Open Recipient accepts
Open Multicast/Selective Replicate OPN(yr),
OPN(fr):
Open Originator
Notes:
1. The actual value is between 0 and the LOGIN_BB_Credit.
2. LPEfx is useful for resetting bypass circuits of NL_Ports that have lost their address.
3. Any NL_Port receiving an MRK attempts to forward it, StorageTek does not originate it.
4. This feature is user-configured. The default setting is "Disabled."
5. Our target will accept the Open Full Duplex, but the FCP simplex protocol does not take advantage of
the full duplex capabilities.
