Solaris中查看硬件信息常用命令

 

1、如何查看cpu的狀態？　

# psrinfo -v

# psrinfo -v Status of virtual processor 0 as of: 03/20/2012 17:16:26   on-line since 03/19/2012 13:37:54.   The i386 processor operates at 3000 MHz,         and has an i387 compatible floating point processor. Status of virtual processor 1 as of: 03/20/2012 17:16:26   on-line since 03/19/2012 13:37:59.   The i386 processor operates at 3000 MHz,         and has an i387 compatible floating point processor.

# mpstat 可以列出多cpu負載的狀態

2、如何查看內存？　

# prtconf | grep 'Memory' 可以查看內存的多少.

# prtconf | grep 'Memory'
Memory size: 3932 Megabytes

# /usr/platform/sun4v/sbin/prtdiag | grep 'Memory'

#  /usr/platform/sun4v/sbin/prtdiag

3、如何動態添加swap分區？

# $su － root ----- 成爲超級用戶
# mkfile 100m /home/swapfile ----- 創建100m的Swap文件
# /usr/sbin/swap －a /path/filename ----- 激活Swap文件
# /usr/sbin/swap －l ----- 驗證swap文件
# /usr/sbin/swap －d /path/filename ----- 取消swap文件
# rm -rf /home/swapfile ----- 刪除swap文件

4、如何查看當前網卡是以何種速率起來的？

# dmesg |grep link

# dmesg | grep link
.[ID 435574 kern.info] NOTICE: e1000g0 link up, 100 Mbps, full duplex

6、如何使用光、軟驅？

一般情況下用：
# /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 --掛接光驅
# mount -F pcfs /dev/diskette0 /floppy --掛接軟驅
solaris定義系統磁盤文件系統說明：
ufs – UNIX文件系統。
zfs -  是Solaris缺省的文件系統。
hsfs – 高密度CD-ROM文件系統，是隻讀文件系統。
pcfs – PC文件系統，支持DOS格式化的軟盤

7、SCSI設備的命名規則是什麼？

帶有總線控制器的硬盤的使用，下面列出了總線控制器的硬盤命名習慣：
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 該原始接口對應第一個控制器的第一個SCSI目標地址的第一個硬盤的第一片(根)
/dev/rdsk/c0t0d0s2 該原始接口對應第一個控制器的第一個SCSI目標地址上的第一個硬盤的第三片(表示

整上硬盤)

8、如何查看硬盤的使用情況？　

# df -k　　　 可以看到已安裝的文件系統的空間大小及剩餘空間大小。
# quota -v　 查看用戶的磁盤空間信息,如果你用quota限制了用戶空間大小的話。
# du -sk *　　　 查看目錄的使用情況
# du -k | sort -n 可以迅速發現那個目錄是最大的。

9、如何查看硬盤物理信息？

# format 這個命令也可以查看硬盤的類型和分區的詳細情況

# format
Searching for disks...done

       2      5    01          0 156230672 156230671

10、查看系統內核命令。　

# isainfo 看內核的bit,
# isainfo -kv 調整內核
# modinfo 顯示可載入的模組
# prtconf 顯示系統硬件配置（周邊設備）
#sysdef 顯示可載入的模組，硬件配置與一些可以調整的核心參考值
#ulimit -a

11、打印當前的OBP版本號

# prtconf -V

# prtconf -V
OBP 4.27.7 2007/10/24 08:23

# /usr/platform/sun4v/sbin/prtdiag –v | grep OBP

# /usr/platform/sun4v/sbin/prtdiag -v | grep OBP
OBP 4.27.7 2007/10/24 08:23

12、查看及啓動系統的64位內核模式

64位模式
# isalist –v
sparcv9+vis sparcv9 sparcv8plus+vis sparcv8plus sparcv8 sparcv8-fsmuld sparcv7 sparc
# isainfo –v
64-bit sparcv9 applications
32-bit sparc applications
# isainfo –b
64

14、如何配置網卡ip？

# ifconfig -a --查看網卡,例如是hme0
# ifconfig hme0 unplumb --停止網卡
# ifconfig hme0 plumb --起用網卡
# ifconfig hme0 inet 192.168.2.3 netmask 255.255.255.0 up --添加ip、子網掩碼
# vi /etc/defaultrouter 添加默認路由的ip
# vi /etc/hostname.hme0 添加主機名
# vi /etc/nodename 添加主機名
# vi /etc/resolv.conf
domain china.com 你的域名
nameserver 202.106.0.20 你使用的nds ip
# vi /etc/nsswitch.conf 更改 hosts：file dns
# vi /etc/hosts
# getent hosts $HOSTNAME
