如何显示系统配置信息
使用 prtconf 和 sysdef 命令的输出可确定与系统连接的磁盘、磁带和 CD-ROM 设备。这些命令的输出会在设备实例旁边显示 driver not attached 消息。由于这些设备始终受某个系统进程监视，因此 driver not attached 消息通常明确表示该设备实例中不存在任何设备。
使用 sysdef 命令可显示系统配置信息，其中包括伪设备、可装入模块以及选定的内核参数。
-
显示与系统连接的所有设备。
例如，SunBlade 1000 上的以下 prtconf -v 输出确定了与系统连接的磁盘设备。详细的磁盘信息在 ssd/fp 驱动程序部分中的 Device Minor Nodes 一节介绍。
$ /usr/sbin/prtconf -v | more . . . Device Minor Nodes: dev=(118,8) dev_path=/pci@8,600000/SUNW,qlc@4/fp@0,0/ssd@w210000 2037bde864,0:a spectype=blk type=minor dev_link=/dev/dsk/c0t1d0s0 dev_path=/pci@8,600000/SUNW,qlc@4/fp@0,0/ssd@w210000 2037bde864,0:a,raw spectype=chr type=minor dev_link=/dev/rdsk/c0t1d0s0 dev=(118,9) dev_path=/pci@8,600000/SUNW,qlc@4/fp@0,0/ssd@w210000 2037bde864,0:b spectype=blk type=minor dev_link=/dev/dsk/c0t1d0s1 dev_path=/pci@8,600000/SUNW,qlc@4/fp@0,0/ssd@w210000 2037bde864,0:b,raw . . . -
显示有关与系统连接的某个特定设备的信息。
例如，SunBlade 1000 上的以下 prtconf 输出显示了 /dev/dsk/c0t1d0s0 的 ssd 实例编号。
# prtconf -v /dev/dsk/c0t1d0s0 ssd, instance #1
-
仅显示与系统连接的设备。
# prtconf | grep -v not
-
显示设备使用信息。
例如，以下 fuser 命令显示了正在访问 /dev/console 设备的进程。
# fuser -d /dev/console /dev/console: 346o 323o #
显示系统和设备的配置信息。
示例 5–1 显示系统配置信息
基于 SPARC 的系统中会显示以下 prtconf 输出。
