Method and apparatus for backing up global memory

A system, comprising:

• a memory;
• and
• at least one processor that is operatively coupled to the memory, the at least one processor being configured to perform the operations of:
• detecting an event indicating a hardware malfunction in one of a plurality of storage processors in a storage system;
• initiating a vault copy operation in response to the event, the vault copy operation being an operation in which a global memory of the storage system is copied to a non-volatile memory, the global memory including a plurality of portions that share a same address space, each portion being implemented by using physical memory hardware of a different one of the plurality of storage processors, wherein the vault copy operation includes executing a plurality of processes, each of the processes being executed on a different one of the plurality of storage processors, each of the processes being arranged to copy a portion of the physical memory hardware of the storage processor on which the process is executed to the non-volatile memory;
• detecting whether the vault copy operation is completed successfully;
• when the vault copy operation is not completed successfully, generating a service ticket for servicing a hardware component that is identified in the event as having malfunctioned and storing the service ticket in a task maintenance database, the service ticket being arranged to include or encode one or more of an identifier of the hardware component and an identifier of one of the plurality of storage processors of which the hardware component is part, the service ticket being arranged to trigger on-site maintenance by technical personnel;
• and
• when the vault copy operation is completed successfully, updating the one or more system logs without generating the service ticket.

A non-transitory computer readable medium storing one or more processor-executable instructions, which, when executed by at least one processor, cause the at least one processor to perform the operations of:

• detecting an event indicating a hardware malfunction in one of a plurality of storage processors in a storage system;
• initiating a vault copy operation in response to the event, the vault copy operation being an operation in which a global memory of the storage system is copied to a non-volatile memory, the global memory including a plurality of portions that share a same address space, each portion being implemented by using physical memory hardware of a different one of the plurality of storage processors, wherein the vault copy operation includes executing a plurality of processes, each of the processes being executed on a different one of the plurality of storage processors, each of the processes being arranged to copy a portion of the physical memory hardware of the storage processor on which the process is executed to the non-volatile memory;
• detecting whether the vault copy operation is completed successfully;
• and
• when the vault copy operation was not completed successfully, generating a service ticket for servicing a hardware component that is identified in the event as having malfunctioned and storing the service ticket in a task maintenance database, the service ticket being arranged to include or encode one or more of an identifier of the hardware component and an identifier of one of the plurality of storage processors of which the hardware component is part, the service ticket being arranged to trigger on-site maintenance by technical personnel;
• and
• when the vault copy operation is completed successfully, updating the one or more system logs without generating the service ticket.
