    • Described are techniques for performing a firmware update. A drive management object determines one or more physical drives matching criteria of a first received request. The drive management object sends to provision drive objects a second request to update firmware on physical drives. Firmware update processing is performed independently for each physical drive. Each provision drive object is associated with one of the physical drives. Firmware update processing for said one physical drive includes determining whether to perform the firmware update at a current point in time; in response to determining to perform the firmware update at the current point in time, performing preparation processing; notifying, upon completion of said preparation processing, a physical drive object associated with said one physical drive to download the firmware update to the one physical drive; and resuming I/O operations to the one physical drive upon successfully completing the firmware update.
    • 描述了用于执行固件更新的技术。 驱动器管理对象确定符合第一接收请求的标准的一个或多个物理驱动器。 驱动器管理对象向物理驱动器发送第二个更新固件的请求。 每个物理驱动器独立执行固件更新处理。 每个配置驱动对象与其中一个物理驱动器相关联。 所述一个物理驱动器的固件更新处理包括确定是否在当前时间点执行固件更新; 响应于确定在当前时间点执行固件更新,执行准备处理; 在完成所述准备处理时通知与所述一个物理驱动器相关联的物理驱动对象,以将所述固件更新下载到所述一个物理驱动器; 并在成功完成固件更新后将I / O操作恢复到一个物理驱动器。
