    • In investigating the cause of a fault in a computer storage system, it is considered useful to previously prepare maintenance logical units (LUs) of a simple structure, the operation of which has been confirmed. If the same number of LUs as servers are prepared for each server as in the prior art, the efficiency is low. Furthermore, securing these LUs complicates assignment of the LUs for construction of a system and a work for addressing the fault. The present invention provides a computer system free of these problems. The computer system has a first computer for executing a first OS (operating system), a second computer for executing a second OS, and a storage array system. The storage array system uses a disk device having a logical unit (LU) for storing a boot loader, as well as the first and second OSes. The boot loader is executed on any one of the two computers, reads in any of the OSes corresponding to the currently operating computer into this operating computer, and executes the read OS.
    • 在调查计算机存储系统中故障的原因时,以前准备了一个简单结构的维护逻辑单元(LU)的有用功能,其操作已得到确认。 如现有技术那样,如果为每个服务器准备与服务器相同数量的LU,则效率低。 此外,确保这些逻辑单元复杂化了用于构建系统的LU的分配和用于解决故障的工作。 本发明提供一种没有这些问题的计算机系统。 计算机系统具有用于执行第一OS(操作系统)的第一计算机,用于执行第二OS的第二计算机和存储阵列系统。 存储阵列系统使用具有用于存储引导加载程序的逻辑单元(LU)以及第一和第二OS的磁盘设备。 引导加载程序在两台计算机中的任何一台上执行,将与当前操作的计算机相对应的任何操作系统读入该操作计算机,并执行读取的OS。

    • An optical scanning device of the present invention includes a simple scanning lens. At least one of opposite surfaces of the lens has a nonarcuate shape, as seen in a polarization plane. At least one of the opposite surfaces is a special toric surface. Further, in a plane perpendicular to the polarization plane, the lens has a meniscus shape concave toward a polarizer. With this configuration, the lens achieves a desirable uniform velocity scanning capability and a desirable field curvature in the main scanning direction. The lens is therefore free from errors in configuration ascribable to molding while reducing the limitation on the tolerance of optical elements in the optical axis direction as to assembly.
    • 本发明的光学扫描装置包括简单的扫描透镜。 透镜的相对表面中的至少一个具有非偏光形状,如在偏振平面中所见。 相对表面中的至少一个是特殊的复曲面。 此外,在垂直于偏振面的平面中,透镜具有向偏振器凹入的弯月形状。 利用这种配置,透镜在主扫描方向上实现期望的均匀速度扫描能力和期望的场曲率。 因此,由于在组装时减少了光学元件在光轴方向上的公差的限制,因此,透镜在构造中不存在由于成型造成的错误。
