Did you ever got the following on chfs command?
"[u]0516-1407 lextendlv Reboot with the 64-bit kernel and try again.[/u]"
aix@root:/ # df -g . Filesystem GB blocks Free %Used Iused %Iused Mounted on /dev/lv_data 1024.00 27.02 98% 51 1% /home/data aix@root:/ # chfs -a size=+1G . [color=red]0516-1407 lextendlv Reboot with the 64-bit kernel and try again. 0516-788 extendlv: Unable to extend logical volume.[/color]
This can happen if you want to extend the filesystem beyond 1024G and you have 32 bits kernel. For that you need 64 bits kernel.
In my situation, for whatever reason, 32 bits kernel was running on 64 bits processor:
aix@root:/ # prtconf | grep bit CPU Type: 64-bit Kernel Type: 32-bit aix@root:/ # bootinfo -y 64 aix@root:/ # bootinfo -K 32 aix@root:/ # ls -l /unix lrwxrwxrwx 1 root system 21 Feb 07 2010 /unix -> /usr/lib/boot/unix_mp aix@root:/ # ls -la /usr/lib/boot/unix_* -r-xr-xr-x 1 root system 15397949 Jan 29 2010 /usr/lib/boot/unix_64 -r-xr-xr-x 1 root system 12531275 Jan 29 2010 /usr/lib/boot/unix_mp
For your information:
/usr/lib/boot/unix_64 = 64 bit multiprocessor kernel
/usr/lib/boot/unix_mp = 32 bit multiprocessor kernel
/usr/lib/boot/unix_up = 32 bit uniprocessor kenrel
In this situation, I had to do the following:
aix@root:/ # ln -sf /usr/lib/boot/unix_64 /unix aix@root:/ # ln -sf /usr/lib/boot/unix_64 /usr/lib/boot/unix aix@root:/ # lslv -m hd5 aix@root:/ # bosboot -ad /dev/ipldevice aix@root:/ # shutdown -Fr aix@root:/ # bootinfo -K (should give you now value 64)
