在AIX上装RAC,顺便学习下上面的命令。之前仅接触过HP-UX和SUN Solaris。

-bash-3.00$ uname -a
AIX aix 3 5 00C97AC04C00powerpc unknown AIX

Purpose:Displays the name of the current operating system.

The uname command writes to standard output the name of the operating system that you are using.
The machin ID number contains 12 characters in the following digit format: xxyyyyyymmss. The xx positions indicate the system and is always 00. The yyyyyy positions contain the unique ID number for the entire system. The mm position represents the model ID. The ss position is the submodel number and is always 00. The model ID describes the ID of the CPU Planar, not the model of the System as a whole.

Purpose :Displays system configuration information.

If you run the prtconf command without any flags, it displays the system model, machine serial, processor type, number of processors, processor clock speed, cpu type, total memory size, network information, filesystem information, paging space information, and devices information.

-bash-3.00$ oslevel -s

Purpose:Reports the latest installed maintenance and technology level of the system.

The oslevel command reports the maintenance and technology levels of the operating system using a subset of all filesets installed on your system. These filesets include the Base Operating System (BOS), base devices, base printers, and X11 2d.
The oslevel command also prints information about maintenance and technology levels, including which filesets are not at a specified maintenance and technology level.

-bash-3.00$ df -m

Purpose:Reports information about space on file systems.

The df command displays information about total space and available space on a file system. The FileSystem parameter
specifies the name of the device on which the file system resides,the directory on which the file system is mounted, or the relative path name of a file system. The File parameter specifies a file or a directory that is not a mount point. If the File parameter is specified, the df command displays information for the file system on which the file or directory resides. If you do not specify the FileSystem or File parameter, the df command displays information for all currently mounted file systems. File system statistics are displayed in units of 512-byte blocks by default.

-bash-3.00$ lsdev -Cc disk
hdisk0 Available 0G-08-01-8,0 16 Bit LVD SCSI Disk Drive
hdisk1 Available 0G-08-01-5,0 16 Bit LVD SCSI Disk Drive

Purpose:Displays devices in the system and their characteristics.
