How to convert AIX 64-bit mode to 32-bit
- Thread starter inunix
- Start date
FYI...and you can find all the info you need all by yourself:
To truly change the kernel to 64-bit, you need to be at least 5.1 oslevel. The
means to change to a 64-bit kernel are:
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
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
bosboot -ad /dev/ipldevice
shutdown -Fr
bootinfo -K (should now be 32)
