ERROR DETECTION AND RECOVERY FOR SYNCHRONOUS INPUT/OUTPUT OPERATIONS |
摘要 |
Aspects include receiving, at an operating system (OS) executing on a server, a notification that an error was detected during execution of a synchronous I/O operation issued by the OS to a persistent storage control unit (SCU). The notification is received from firmware executing on the server and it includes a command response block that includes error condition information about the error. The method can also include selecting, by the OS, a recovery operation for the synchronous I/O operation. The selecting is based on the error condition information about the error in the command response block. The selected recovery option is performed by the OS. |

1. A method for performing synchronous input/output (I/O) error detection, reporting, and recovery, the method comprising:
receiving, at an operating system (OS) executing on a server, a notification that an error was detected during execution of a synchronous I/O operation issued by the OS to a persistent storage control unit (SCU), the notification received from firmware executing on the server and including a command response block that includes error condition information about the error; selecting, by the OS, a recovery operation for the synchronous I/O operation, the selecting based on the error condition information about the error in the command response block; and performing, by the OS, the recovery operation. |
