Scsi command is to request to service.The client-server end of SCSI protocol is mapped to specific interconnection by " SCSItransport "
System.Initiator is one end of SCSItransport, and target is the other end.
ISCSI (Internet Small Computer SystemInterface) agreement use TCP/IP as
SCSItransport.By transmitting scsi data packet on TCP/IP, iSCSI provides a kind of solution of interoperable,
Existing Internet infrastructure and management tool is utilized in it, and breaches distance limitation.With need client cables
Traditional fiber is different, and iSCI can be run in existing network system.Due to its scalability and economic benefit, iSCSI is
Through becoming popular SAN (Storage areanetwork) agreement.ISCSI is defined in IETF RFC 3720iSCSI, and
It is updated in IETF RFC 5048iSCSICorrections andClarificationsRFC.
Current iSCSI protocol consistency software I scsisim testing process, as shown in Fig. 1.The original of Iscsisim test
Reason mainly sends test PDU message by the simulation end initiator and negotiates PDU message to the end target, and is receiving
After the PDU message that the end target is replied, whether the verification end target protocol realization is consistent.Current iscsisim test directly will
Keyword carries out parsing comparison one by one for PDU message and local PDU verification file.But it is different the PDU message of target reply
Key sequence is variant, needs to adjust local PDU message checking file when testing different target according to actual order, and
Current iscsisim test does not save protocol negotiation as a result, the test that current target is not supported can not be rejected according to negotiation result
?.
In view of the above-mentioned problems, the invention proposes the improvement sides of iSCSI protocol Conformance Test Software iscsisim a kind of
Method.It is intended to increase the flexibility of iscsisim, realizes that automatic rejection target does not support item to test, reduce artificial selection, improve
Testing efficiency.
Summary of the invention
In order to compensate for the shortcomings of the prior art, the present invention provides a kind of iSCSI protocol consistency at low cost, high-efficient
The improved method of test software iscsisim.
The present invention is achieved through the following technical solutions:
A kind of improved method of iSCSI protocol Conformance Test Software iscsisim, it is characterised in that the following steps are included:
(1) iscsisim software, which is simulated the end initiator and sent to the end target, negotiates PDU message；
(2) it after iscsisim software receives target negotiation packet, is saved by protocol negotiation object module and target
The protocol option that the target of negotiation is specifically supported, the test option that iscsisim software selects target to support according to the option
Carry out testing protocol consistency；
(3) iscsisim software simulates initiator according to the protocol option of negotiation and sends test PDU report to target
Text；
(4) after iscsisim software receives PDU message, whether agreement one is met by the verification of PDU message comparison module
Cause property.
In the step (2), after the good protocol fields of the end iscsisim and target initial negotiation, iscsisim passes through agreement
Negotiation result module saves the result after negotiating in global variable；In the step (4), iscsisim is according to the association consulted
It discusses field and reads local corresponding PDU message checking file.
In the step (4), parsing receives the PDU message comparison module respectively in a manner of key-value
The PDU message and local PDU message checking file that the end target is replied, then the value value of more identical key value whether one
It causes, to determine whether PDU message meets protocol conformance.
When iSCSI protocol does not support HeaderDigest agreement item, the end target is replied PDU message and is not supported
HeaderDigest, iscsisim save the negotiation result, reject the test case comprising test HeaderDigest test item,
Other test cases are sent, iscsisim is parsed in a manner of key-value receives PDU message and local PDU message checking text
Part is compared the identical value value of key, is judged whether to meet protocol conformance with this.
The beneficial effects of the present invention are: the improved method of iSCSI protocol Conformance Test Software iscsisim, passes through increasing
Add PDU message comparison module to realize PDU message consistency desired result and target replys PDU message keyword sequence and decouples, increasing
The flexibility for having added iscsisim realizes automatic rejection target and does not support by increasing protocol negotiation result global module
Item test, reduces artificial selection, improves testing efficiency.
