Switching to the 32bit Kernel

  1. # ln -sf /usr/lib/boot/unix_mp /unix
  2. # ln -sf /usr/lib/boot/unix_mp /usr/lib/boot/unix
  3. You will need to note which hdisks that hd5 appears on.
    1. # lslv -m hd5
  4. Change the base operating system boot devices repeat for each disk listed in previous step.
    1. # # bosboot -ad <hdisk#>
  5. Restart the server to apply the changes.
  6. Verify that the server is running the 32 bit kernel.
    1. # bootinfo -K

Switching to the 64 bit Kernel

  1. # ln -sf /usr/lib/boot/unix_64 /unix
  2. # ln -sf /usr/lib/boot/unix_64 /usr/lib/boot/unix
  3. You will need to note which hdisks that hd5 appears on.
    1. # lslv -m hd5
  4. Change the base operating system boot devices repeat for each disk listed in previous step.
    1. # # bosboot -ad <hdisk#>
  5. Restart the server to apply the changes.
  6. Verify that the server is running the 64 bit kernel.
    1. # bootinfo -K
