Method, apparatus, and device for cleaning residual paths on host end, and storage medium

A device for cleaning residual paths on a host end, comprising:

• a memory configured to store a computer program;
• and
• a processor configured to implement, when executing the computer program, operations comprising:
• acquiring device information of subordinate devices of a plurality of paths;
• determining, according to the device information, whether links corresponding to the subordinate devices are all abnormal;
• acquiring a global identification number and connection information of each subordinate device in a case that the links corresponding to the subordinate devices are all abnormal;
• when the global identification number is not null and the connection information is successfully acquired, querying a mapping state of a volume corresponding to the global identification number and a mapped host according to the global identification number and the connection information;
• and
• when the volume is not in the mapping state or the mapped host is not a target host, deleting the plurality of paths and the subordinate devices.

A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium, having stored thereon, a computer program when, when executed by a processor, implements operations comprising:

• acquiring device information of subordinate devices of a plurality of paths;
• determining, according to the device information, whether links corresponding to the subordinate devices are all abnormal;
• acquiring a global identification number and connection information of each subordinate device in a case that the links corresponding to the subordinate devices are all abnormal;
• when the global identification number is not null and the connection information is successfully acquired, querying a mapping state of a volume corresponding to the global identification number and a mapped host according to the global identification number and the connection information;
• and
• when the volume is not in the mapping state or the mapped host is not a target host, deleting the plurality of paths and the subordinate devices.
