The uname -Ls command will show you the partition number and the partition (lpar) name. When setting the resource allocation for a partition profile, set the minimum to the absolute bare minimum, and set the maximum as high as possible.

For memory there are special considerations:

• If you set the maximum too low and you wish to exceed above the maximum amount of memory defined in the active profile, you can't simply adjust the profile and put extra memory in via DLPAR, because the LPAR has been initialized with a certain page table size, based on the maximum amount of memory setting. Therefore, a reboot will be required when you wish to use more memory than defined in the active profile. If you do try it however, you'll receive the following error:

  HMCERRV3DLPAR018: There is no memory available for dynamic logical partioning on this partition.

• If you set the maximum too high, the partition will be initialize with a large page table size, which uses too much memory for overhead, which you might never use.
