aix kernel from 32bit to 64 bit question

[cpu533]

Hi All,

I have read some posts regarding this issue. Here is waht from IBM.
#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

My question is regarding the ipldevice. Should I replace ipldevice with real device name? Some people said you should use the real name. And if so, in a mirroredVg environment, which disk should I use.
Below are some information from our system.

#lslv -m hd5
hd5:N/A
PV COPIES IN BAND DISTRIBUTION
hdisk0 001:000:000 100% 001:000:000:000:000
hdisk1 001:000:000 100% 001:000:000:000:000

#bootinfo -b
hdisk0

So what is correct bosboot command to use?

Thanks,
Denny

The ipldevice is just a link to rhdisk so leave as is.

To switch from 32-bit mode to 64-bit mode run the following commands, in the given order:

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 show 64)

bootinfo -b is showing you the last boot device used.
