Veritas NetBackup™ 设备配置指南

关于 Linux 上的 SAN 客户端

Linux 主机上的 NetBackup SAN 客户端需要 SCSI 通用 (sg) 驱动程序和直通磁带驱动器设备文件，将通信量传递到 NetBackup FT 介质服务器上。从 SAN 客户端进行 SCSI 查询的过程中，介质服务器 FT 设备显示为 ARCHIVE Python 磁带设备。（但是，它们并不是磁带设备，也不会在 NetBackup 设备发现中显示为磁带设备。）

应验证是否具有正确的驱动程序和设备文件。

验证 Linux 驱动程序

如果 Linux 操作系统未自动添加所有 SCSI 设备文件，则您可以手动执行此操作。 下面是一个代码示例，可以将该代码包括在 /etc/rc.local 文件中以便在控制器 0-2 上添加 LUN 1 和 目标 0-7。请注意最后一行是 MAKEDEV 命令，该命令生成所需的设备文件。包括在 /etc/rc.local 文件中的代码取决于硬件环境。
