Method to identify unique host applications running within a storage controller

A computer readable medium including a persistent memory, storing a computer program of machine-readable instructions executable by a processor to perform operations to operate a controller, the instructions comprising:

• computer readable code for receiving a command associated with at least one operation;
• computer readable code for determining a CPU channel path based on the received command;
• computer readable code for determining a unique job identifier based on the received command;
• computer readable code for determining a state based on the received command;
• computer readable code for updating at least one data matrix based on the determined state, unique job identifier and CPU channel path;
• and
• computer readable code for operating the controller based on the updated data matrix wherein computer readable code for operating the controller based on the updated data matrix comprises:
• computer readable code for detecting at least one job-caused fault condition wherein one or more of the received commands of a job which caused the detected fault condition is the source of the detected fault condition;
• computer readable code for determining each unique job identifier stored within the data matrix based on the detected job-caused fault condition;
• and computer readable code for displaying a list of each determined unique job identifier based on the determination.

A controller comprising:

• a persistent memory, the memory including machine-readable instructions executable by a processor to perform operations to operate a controller, the instructions comprising:
• computer readable code for receiving a command associated with at least one operation;
• computer readable code for determining a CPU channel path based on the received command;
• computer readable code for determining a unique job identifier based on the received command;
• computer readable code for determining a state based on the received command;
• computer readable code for updating at least one data matrix based on the determined state, unique job identifier and CPU channel path;
• and
• computer readable code for operating the controller based on the updated data matrix wherein computer readable code for operating the controller based on the updated data matrix comprises:
• computer readable code for detecting at least one job-caused fault condition wherein one or more of the received commands of a job which caused the detected fault condition is the source of the detected fault condition;
• computer readable code for determining each unique job identifier stored within the data matrix based on the detected job-caused fault condition;
• and computer readable code for displaying a list of each determined unique job identifier based on the determination.

A method for operating a controller, the method comprising:

• receiving a command associated with at least one operation;
• receiving a CPU channel path based on the received command;
• receiving a unique job identifier based on the received command;
• receiving a state based on the received command;
• updating at least one data matrix based on the received state, unique job identifier and CPU channel path;
• and
• operating the controller based on the updated data matrix wherein operating the controller based on the updated data matrix comprises:
• detecting at least one job-caused fault condition wherein one or more of the received commands of a job which caused the detected fault condition is the source of the detected fault condition;
• determining each unique job identifier stored within the data matrix based on the detected job-caused fault condition;
• and displaying a list of each determined unique job identifier based on the determination.
