Method, electronic device and computer program product for dual-processor storage system

An electronic device, comprising:

• at least two processors;
• and
• at least one memory including computer program instructions, the at least one memory and the computer program instructions configured, with a first processor of the at least two processors, to cause the electronic device to:
• detect, at the first processor, a change in an initial logical unit corresponding to a storage area in a physical storage device of the storage system;
• determine, based on the change in the initial logical unit, a plurality of update operations to be performed on a mapped logical unit driver mapping a plurality of initial logical units including the initial logical unit to a plurality of mapped logical units;
• and
• send an indication of the plurality of update operations to a second processor of the storage system, to cause the second processor to perform the plurality of update operations on a peer mapped logical unit driver associated with the mapped logical unit driver.

A computer program product having a non-transitory computer readable medium which stores a set of instructions to operate a dual-processor storage system;

• the set of instructions, when carried out by computerized circuitry, causing the computerized circuitry to perform a method of:
• detecting, at a first processor of the dual-processor storage system, a change in an initial logical unit corresponding to a storage area in a physical storage device of the dual-processor storage system;
• determining, based on the change in the initial logical unit, a plurality of update operations to be performed on a mapped logical unit driver mapping a plurality of initial logical units including the initial logical unit to a plurality of mapped logical units;
• and
• sending an indication of the plurality of update operations to a second processor of the dual-processor storage system, to cause the second processor to perform the plurality of update operations on a peer mapped logical unit driver associated with the mapped logical unit driver.
