Storage apparatus, storage control device, and recording medium with execution command pausing or stopping

A storage control device comprising:

• a memory;
• and
• a processor coupled to the memory and configured to:
• receive an instruction from external software as a task,
• generate a command set for controlling a non-volatile storage device,
• execute a command included in the generated command set,
• control firmware revision processing of a storage apparatus,
• stop execution of the command after performing processing for suppressing abnormality detection of the external software at a timing at which the command is not executable during the firmware revision processing,
• provide an instruction to pause the execution of the command at a timing of separating and incorporating a corresponding one of a plurality of control devices and at a timing of synchronizing a cache table with another one of the plurality of control devices, and
• provide an instruction to completely stop the execution of the command at a timing of switching the another one of the plurality of control devices to a master control device.

A non-transitory computer-readable recording medium having stored therein a program that causes a computer to execute a storage control processing, the processing comprising:

• receiving an instruction from external software as a task;
• generating a command set for controlling a non-volatile storage device;
• executing a command included in the generated command set;
• controlling firmware revision processing of the storage apparatus;
• stopping execution of the command after performing processing for suppressing abnormality detection of the external software at a timing at which the command is not executable during the firmware revision processing;
• providing an instruction to pause the execution of the command at a timing of separating and incorporating a corresponding one of a plurality of control devices and at a timing of synchronizing a cache table with another one of the plurality of control devices;
• and
• providing an instruction to completely stop the execution of the command at a timing of switching the another one of the plurality of control devices to a master control device.
