In my earlier post I talk about increasin the size of a file system on AIX
http://shettymayur.blogspot.com/2011/01/how-to-increase-file-system-size-on-aix.html
In this post I created a 100GB SAN volume, which I mapped to my AIX 7.1 host.
Using smitty I created a 64GB jfs2 file system on the volume.
The volume that was mapped to the host was 100GB, but when I tried to increase the file system size beyond 64GB I get the below message.
We see that it's complaining that the maximum number LP is 512. LV can go up to 512 LPs, each LP is 128 MB , so 512 x 128MB= 64 GB
Below we below see the command to increase the LPs to 1024, this will give us a max file system of 128 GB
