Management of microcode errors in a storage operation

A system for managing a microcode error in a storage operation comprising:

• one or more storage devices configured to perform the storage operation that produces the microcode error that triggers a warm start operation issued by a storage system to collect data for problem diagnostics, and an error code corresponding to the microcode error;
• a metadata table that stores a metadata error path signature for the error code;
• a storage controller configured to:
• receive the error code and a received error path signature for the error code from the one or more storage devices, wherein the received error path signature identifies a series of instructions executed during the storage operation that causes the storage operation to return the error code,
• identify, within the metadata table, the metadata error path signature for the error code,
• determine whether the received error path signature for the error code substantially matches the metadata error path signature for the error code, and
• initiate a mitigation action in response to the received error path signature for the error code substantially matching the metadata error path signature for the error code, the mitigation action indicates an action to be taken to recover from the microcode error.

A computer program product for managing a microcode error in a storage operation, the computer program product comprising a computer readable storage medium having program code embodied therewith, the program code comprising computer readable program code configured to:

• receive an error code that corresponds to the microcode error that triggers a warm start operation issued by a storage system to collect data for problem diagnostics;
• receive a received error path signature for the error code, wherein the received error path signature identifies a series of instructions executed during the storage operation that causes the storage operation to return the error code;
• identify a metadata error path signature for the error code within a metadata table;
• determine whether the received error path signature for the error code substantially matches the metadata error path signature for the error code;
• and
• initiate a mitigation action in response to the received error path signature for the error code substantially matching the metadata error path signature for the error code, the mitigation action indicates an action to be taken to recover from the microcode error.
