Check /usr/lib/boot
Link unix points to your kernel (32 or 64)
If there is a directory called unix_64, you 64 bit kernel is there
From 32-bit to 64-bit:
ln -sf /usr/lib/boot/unix_64 /unix
ln -sf /usr/lib/boot/unix_64 /usr/lib/boot/unix
lslv -m hd5
bosboot -ad /dev/ipldevice
shutdown -Fr
bootinfo -K (should now be 64)
To change the kernel back to 32-bit:
From 64-bit to 32-bit:
ln -sf /usr/lib/boot/unix_mp /unix
ln -sf /usr/lib/boot/unix_mp /usr/lib/boot/unix
lslv -m hd5
bosboot -ad /dev/ipldevice
shutdown -Fr
bootinfo -K (should now be 32)
