Check HP-UX System Serial Number

In HP-UX, we can use command cstm to check the system serial number. cstm is installed with the OnlineDiagnostics / Support Tools Bundle on HP-UX 9000 systems.

# echo "sc product system;info;wait;il" | cstm | grep -i "system serial"
System Serial Number...: ABC1234DE

or

# echo "sel path system\ninfolog\nexit"|cstm|grep "System Serial"
System Serial Number...: ABC1234DE

For HP-UX 11i the following command also works:

# getconf MACHINE_SERIAL
ABC1234DE

And for HP-UX 11i v2 on Itanium-based systems, use the machinfo command:

# machinfo | grep "machine serial"
machine serial number = ABC1234DE
