PROGRAMMING INTERFACE OPERATIONS IN A PORT IN COMMUNICATION WITH A DRIVER FOR REINITIALIZATION OF STORAGE CONTROLLER ELEMENTS |
| 摘要 |
An embedded port of a host bus adapter of a storage controller receives, from a driver of the host bus adapter, a first set of commands to quiesce I/O operations in the embedded port for a first period, wherein hardware resets of buses and other logic to which the embedded port is connected are performed in the first period of quiescing of I/O operations. One or more commands are received to resume selected I/O operations in the embedded port. A second set of commands is received to quiesce I/O operations for a second period. A command is received to allow normal I/O operations, subsequent to the driver being reinitialized during the second period of quiescing of I/O operations. |

1. A method performed by an embedded port of a host bus adapter of a storage controller, the method comprising:
receiving, from a driver of the host bus adapter, a first set of commands to quiesce I/O operations in the embedded port for a first period, wherein hardware resets of buses and other logic to which the embedded port is connected are performed in the first period of quiescing of I/O operations; receiving one or more commands to resume selected I/O operations in the embedded port; receiving a second set of commands to quiesce I/O operations for a second period; and receiving a command to allow normal I/O operations, subsequent to the driver being reinitialized during the second period of quiescing of I/O operations. |
