2、如何查看内存？ # prtconf | grep 'Memory' 可以查看内存的多少. - # prtconf | grep 'Memory'
- Memory size: 3932 Megabytes
# /usr/platform/sun4v/sbin/prtdiag | grep 'Memory' - # /usr/platform/sun4v/sbin/prtdiag
- System Configuration: Oracle Corporation sun4v Sun Fire(TM) T1000
- Memory size: 1852 Megabytes

3、如何动态添加swap分区？ # $su － root ----- 成为超级用户 # mkfile 100m /home/swapfile ----- 创建100m的Swap文件 # /usr/sbin/swap －a /path/filename ----- 激活Swap文件 # /usr/sbin/swap －l ----- 验证swap文件 # /usr/sbin/swap －d /path/filename ----- 取消swap文件 # rm -rf /home/swapfile ----- 删除swap文件4、如何查看当前网卡是以何种速率起来的？ # dmesg |grep link - # dmesg | grep link

6、如何使用光、软驱？ 一般情况下用： # /etc/init.d/volmgt start # volcheck 以上方法不行，用： # /etc/init.d/volmgt stop # mount -F hsfs -o ro /dev/dsk/c0t6d0s0 /cdrom --挂接光驱 # mount -F pcfs /dev/diskette0 /floppy --挂接软驱 solaris定义系统磁盘文件系统说明： ufs – UNIX文件系统。 zfs - 是Solaris缺省的文件系统。 hsfs – 高密度CD-ROM文件系统，是只读文件系统。 pcfs – PC文件系统，支持DOS格式化的软盘7、SCSI设备的命名规则是什么？ 带有总线控制器的硬盘的使用，下面列出了总线控制器的硬盘命名习惯： cWtXdYsZ c Logical controller number t Physical bus target number d Drive number s Slice (or partition) number (0 to 7) 例如： /dev/rdsk/c0t0d0s0 该原始接口对应第一个控制器的第一个SCSI目标地址的第一个硬盘的第一片(根) /dev/rdsk/c0t0d0s2 该原始接口对应第一个控制器的第一个SCSI目标地址上的第一个硬盘的第三片(表示 整上硬盘) 8、如何查看硬盘的使用情况？ # df -k 可以看到已安装的文件系统的空间大小及剩余空间大小。 # quota -v 查看用户的磁盘空间信息,如果你用quota限制了用户空间大小的话。 # du -sk * 查看目录的使用情况 # du -k | sort -n 可以迅速发现那个目录是最大的。9、如何查看硬盘物理信息？ # format 这个命令也可以查看硬盘的类型和分区的详细情况 - # format
