From documents I came to know that AIX 5.1 (with some ML1 or ML2 I guess) with POWER4 support is capable of static LPAR. I have one application which uses uname -L command, and application will work...
I have already gone through this document but I have one AIX 5.1 with PowerPC_604e support machine, and when i ran 'uname -L' command it is returning "-1 NULL".
