    Hello,

    We are running AIX 5.3 64-bit kernel. can you please let me know how to change it to 32-bit kernel.

    regards

    thanks for the prompt reply. but the link refers to change from 32-bit kernel to 64-bit kernel. i need to convert from 64-bit kernel to 32-bit kernel.

    regards

    If you read what the commands are doing, it's trivial to reverse the process to boot from the 32bit kernel.

    lslv -m hd5
    bosboot -ad /dev/ipldevice
    shutdown -Fr
    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
