摘要： 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.

摘要： A single-acting, clearance sensing slack adjuster for brakes is provided. The slack adjuster includes a displaceable brake actuation assembly (28), a rotatable driving member (52), a rotatable intermediate member (60) and a rotatable driven member (56). The driven member is in driving relationship with a rotatable adjustment member (50) which is rotatable in a given direction to advance a brake friction member (32) to maintain the running clearance (38) within predetermined limits. A linear to rotational motion assembly (76-80) is provided to rotate the driving member in the slack decreasing direction of rotation in response to greater than predetermined movement (82) of the brake actuation assembly. A first coil clutch (20) couples the driving and intermediate members while a second coil clutch (72) couples the intermediate and driven members. One clutch (72) delivers torque in the given direction in its low torque transmitting capacity direction of rotation and that torque capacity is less than is required to rotate the rotatable actuation members when the brake friction members are engaged.
