The workflow thereof will be described in detail below.
Step 1: and selecting a new storage resource service by the user on a system service request interface.
Step 2: when a user inputs a service request list, the intelligent self-checking module acquires data in a configuration management library in real time, and if the user inputs parameters wrongly or unreasonably, refined error information and related suggestions are prompted on a foreground in real time to help the user to correct the parameters; if the user input is correct, the system executes the target storage determination logic to determine the target storage or storage pair. And clicking to submit the parameters without errors.
The main parameters of the storage resource new creation module are shown in table 1.
Table 1 storage resource creation module input parameters
And in the intelligent self-checking process in the new building process of the storage resource, parameter validity check is carried out on the parameters input by the user in real time according to the data in the configuration management database and each parameter rule. If the parameters are illegal, outputting parameter error information on a user input interface in real time and prompting a modification suggestion to allow the user to input the requested parameters again.
The checking rule of the parameter validity is as follows:
1) when the user service request is newly created for the storage resource, whether the parameters included in the user service request are 10 parameters or not is judged;
2) whether all parameters are letter or number only;
3) capacity: must be a number;
4) host1 name, host2 name: the length is less than 31 bits;
5) host1 type, host2 type: but only 0(linux),3(hp) or 4 (aix);
6) host1fc port1, host1fc port2, host2 fc port1, host2 fc port: the length is 16 bits, and only numbers and letters can be used;
7) and checking the name of the deployment unit and the host name filled in the user service request, and whether the WWPN of the host exists, if so, prompting the existence by the intelligent self-checking module, and suggesting to replace the name or checking whether the filled information is correct.

3) creating a LUN group SG;
4) creating a port group PG;
5) creating a mapping of a host to a master group IG;
6) creating mapping from the LUN to the LUN group SG (carrying out batch query on the LUN group to obtain a target LUN, and then mapping the target LUN to the SG);
7) creating a Mapping from the port to the port group PG (the port is determined according to Mapping View associated with the port group at least);
8) and creating the Mapping from the host group IG, the LUN group SG and the port group PG to Mapping View.
Step 6: after the execution of step 5 is finished, the switch Zone new file is output for use by the switch Zone new module.
And 7: the system prompts the success of the new establishment of the storage resource.
After the new storage resource is executed, a switch zone new-creation operation needs to be executed, which is a logical connection relationship established on the basis of physical connection, so that the host can scan the storage resource information allocated by the storage, and if the switch zone new creation is not performed, the host cannot identify the storage resource, and the purpose of creating the new storage resource cannot be achieved. The specific work flow of the switch zone new building module comprises the following steps:
step 1: and executing zone change database initialization operation.
Step 2: with the switch-activated zone file, a show _ zone file is generated, and a zone info table is created.
And step 3: after the step 1, a zoneaddinfo table is created according to the switch zone new file output by the storage resource new creation module.
And 4, step 4: after step 3, a differential comparison analysis is performed. If the same item exists, an error log is output, the system starts an intelligent self-checking module, the error log is analyzed, an error checking result is output, and the error reason and a solution proposal are prompted; if there is no identical item, a zone new command is generated, a zone add to zone command is generated, and a zone activate command is generated. After completion, the zone change database is initialized.
And 5: and 4, connecting the switch, executing the newly-built storage zone, sequentially executing the commands of newly-built zone, adding zone into zone set, activating zone set and the like, finishing the newly-built zone of the switch, disconnecting the connection of the switch, and prompting the success of the newly-built zone of the switch by the system.

And automatically allocating proper storage resources to expand the capacity of the application system according to parameter information such as the name, the capacity, the host name, the type of the operating system, the WWPN of the host HBA card and the like of the deployment unit of the application system. The workflow thereof will be described in detail below.
Step 1: and selecting storage resource capacity expansion service by the user on a system service request interface.
Step 2, when a user inputs a service request list, the intelligent self-checking module acquires data in a configuration management library in real time, if the user inputs parameters wrongly or unreasonably, refined error information and related suggestions are prompted on a foreground in real time, and the user is helped to correct the parameters; if the user input is correct, the system executes the target storage determination logic to determine the target storage or storage pair. And clicking to submit the parameters without errors.
The main parameters of the storage resource capacity expansion module are shown in table 2.
TABLE 2 storage resource expansion Module input parameters
And in the intelligent self-checking process in the storage resource expansion process, parameter validity check is carried out on the parameters input by the user in real time according to the data in the configuration management database and each parameter rule. If the parameters are illegal, outputting parameter error information on a user input interface in real time and prompting a modification suggestion to allow the user to input the requested parameters again.
