    • A computer storage system includes a supervisor algorithm to detect a host computer's initiator logging in. The supervisor algorithm identifies data storage devices associated with the newly logged-on initiator and tags logical unit number control blocks (“LUNCBs”) as having priority in an initiation process. The supervisor algorithm assigns a task control block to each of the identified data storage devices and invokes a logical unit number (“LUN”) initialization algorithm. If the supervisor algorithm was invoked during an initial microcode load (“IML”) event, the LUN initialization algorithm initializes each of the identified data storage devices. However, if the supervisor algorithm was invoked during a warmstart procedure, the LUN initialization algorithm first checks to make sure the LUNCB was not mistakenly written too. If not, the LUN initialization algorithm terminates without initializing the associated data storage device. Otherwise, the associated data storage device is initialized and the LUN initialization algorithm terminates.
    • 计算机存储系统包括用于检测主计算机的发起者登录的监督器算法。主管程序识别与新登录的发起者相关联的数据存储设备,并将逻辑单元号控制块(“LUNCB”)标记为在启动中具有优先权 处理。 管理员算法将任务控制块分配给每个识别的数据存储设备,并调用逻辑单元号(“LUN”)初始化算法。 如果在初始微代码加载(“IML”)事件期间调用了管理程序算法,则LUN初始化算法会初始化每个标识的数据存储设备。 但是,如果在启动过程中调用了Supervisor算法,则LUN初始化算法首先检查LUNCB是否也被错误地写入。 如果没有,则LUN初始化算法将在不初始化关联的数据存储设备的情况下终止。 否则,关联的数据存储设备被初始化并且LUN初始化算法终止。
