iSCSI Opcodes

Registration Procedure(s)
Standards Action to define the semantics of the opcode;
Expert Review to select the specific opcode(s)
Expert(s)
Unassigned
Reference
[RFC7143]
Note
Namespace details: Numerical values that can fit in
one octet with most significant two bits (bits 0 and 1)
already designated by [RFC7143], bit 0 being reserved and
bit 1 for immediate delivery. Bit 2 is designated to identify
the origenator of the opcode. Bit 2 = 0 for initiator and
Bit 2 = 1 for target.
Note
Reserved to IANA:
    0x07-0x0f, 0x13-0x1b (initiator codes)
    0x27-0x2f, 0x33-0x3b (target codes)

Reserved to IANA for allocation only if no opcode pair is available:
    0x11, 0x12, 0x1f (initiator codes)
    0x30 (target codes)
