domain_name# isainfo -k sparcv9
The returned value, sparcv9, indicates that the domain is running the 64-bit operating mode; otherwise, the domain is running in 32-bit mode.
You can also use another command, isalist, to check the operating mode; however, the return value, sparcv9+vis, differs from the return value of the isainfo -k command. The values are synonymous. They both indicate that the domain is running in 64-bit mode.
