Problems solved by technology

However, the order of PDU message keywords replied by different targets is different. When testing different targets, the local PDU message verification file needs to be adjusted according to the actual order, and the current iscsisim test does not save the protocol negotiation results, and the current target cannot be eliminated according to the negotiation results. Test items not supported

Embodiment Construction

[0019] The accompanying drawings are a specific embodiment of the present invention, and the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] The improved method of the iSCSI protocol conformance testing software iscsisim comprises the following steps:

[0021] (1) The iscsisim software simulates that the initiator end sends a negotiation PDU message to the target end;

[0022] (2) After the iscsisim software receives the target negotiation message, it saves the protocol option specifically supported by the target negotiated with the target through the protocol negotiation result module, and the iscsisim software selects the test option supported by the target to carry out the protocol consistency test according to the option;

[0023] (3) The iscsisim software simulates the initiator to send a test PDU message to the target according to the negotiated protocol option;

[0024] (4) After the iscsisim software receives...

Abstract

The invention particularly relates to an improved method of iscsisim, an iSCSI protocol consistency test software. The improved method of the iSCSI protocol conformance test software iscsisim adds a PDU packet comparison module, which is responsible for parsing the received PDU packet of the target end and the local PDU packet verification file in a key-value manner, and then compares the same key value. Whether the value of the PDU is correct to determine whether the PDU message satisfies the protocol consistency; a protocol negotiation result module is also added, which is responsible for saving the protocol options specifically supported by the target negotiated with the target. iscsisim selects the test options supported by the target according to this option. Conformance testing. The improved method of the iSCSI protocol conformance testing software iscsisim, by adding a PDU message comparison module, realizes the PDU message consistency check and the target reply PDU message keyword sequence decoupling, which increases the flexibility of iscsisim. The global module of the negotiation result realizes the automatic elimination of the test of the unsupported items of the target, which reduces the manual selection and improves the test efficiency.

Description

technical field [0001] The invention relates to the technical field of iSCSI protocol conformance testing, in particular to an improved method of iSCSI protocol conformance testing software iscsisim. Background technique [0002] SCSI (SmallComputer SystemInterface) is a protocol cluster for interacting with I / O devices, especially storage devices. The SCSI client, or "initiator," sends SCSI commands to the logical unit on the server side, or "target," to request services. "SCSItransport" maps the client-server side of the SCSI protocol to a specific interconnect system. Initiator is one end of SCSItransport, target is the other end. [0003] The iSCSI (Internet Small Computer System Interface) protocol uses TCP / IP as the SCSI transport. By transporting SCSI packets over TCP / IP, iSCSI provides an interoperable solution that leverages existing Internet infrastructure and management tools and overcomes distance limitations. Unlike traditional fiber optics that require dedi...
