Description
Technical Field
The invention relates to the technical field of computer storage, in particular to a test method for port virtualization of a multi-control storage system.
Background
With the advent of the big data age, data has become the most important wealth for businesses, institutions, and individuals. Data concentration has become a trend, and more enterprises select a self-built (cloud) storage system or directly migrate data to a cloud. As a result, the storage system is convenient and has higher requirements for stability and reliability.
At present, most of storage systems adopt a multi-controller redundancy mode, and the safety and reliability of the systems are improved. However, when one node in the multi-control storage system is down, the server will report a large amount of abnormal logs of port down and switching. The storage system may also be in a degraded state and performance may degrade under high load. The extremely poor experience is brought to the user, and the acceptance of the user to the product is reduced.
The above problems are solved by virtualizing the storage system ports, which is to display a single fibre channel protocol port as multiple distinct ports, and to provide a separate port identification for each operating system image behind the port, as if each operating system image had its own unique physical port. The function is realized on the storage, which is embodied in that when the node is down, the WWPN (World wide port number) of the virtual port is automatically migrated to other nodes, the host end cannot sense the WWPN and the multicast cannot be changed, so that the service performance is improved. However, there is no suitable method for testing the virtualized storage system port, and for products shipped from factories, it cannot be guaranteed whether the storage system with the virtualized port can work normally.

IO service flow:
starting: stable, no interruption, no error;
transiting: stable, no interruption, no error;
and (3) disabling: stable, no interruption, no error.
A server side:
starting: when the node serves, only the virtual port path is active;
transiting: when the node service is carried out, the virtual port and the physical port are in an active state;

A storage end:
starting: when the node serves, the virtual port is migrated to other control nodes;
