在P630中AIX5.1系统由64位转换成32位模式

Before the kernel change, pls verify the existing kernel first :

#bootinfo -K
64 -----> 64-bit kernel
32 -----> 32-bit kernel


The following example provides the commands to change the 64-bit kernel to 32-bit kernel :


# 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

After the system has rebooted, it will be running the 32-bit kernel.

Don't change the kernel to 32-bit , if your rootvg is running jfs2 .
jfs2 must be running under 64-bit kernel enable
