- lscfg Detailled configuration of my system
- lscfg | grep proc Display number of processor
- oslevel Returns the major level of the OS
- oslevel -r Returns the detailled level of the OS
- oslevel -s To see which service pack is currently installed
- uname -a Type of the machine
- unmae -uM Type of the machine and serial number
- oslevel Reports the latest installed maintenance level of the system (VIO)
- lspv To display the number of hard disks on your system
- lspv hdisk1 To find details about hdisk1
