Determine if Solaris is running in 32 or 64 bit mode
The isainfo command can be used to determine if a Solaris system has been configured to run in 32 or 64 bit mode.
Run the command
isainfo -v
If the system is running in 32 bit mode, you will see the following output:
32-bit sparc applications
On a 64 bit Solaris system, you’ll see:
64-bit sparcv9 applications
32-bit sparc applications

/usr/bin/isainfo -kv
If your OS is 64-bit, you will see output like:
64-bit sparcv9 kernel modules
If your OS is 32-bit, you will get this output:
32-bit sparc kernel modules
