Partitioning Tips—Processors, Memory, NWSDs, and
LPARs
• Run STRSST (Start System Service Tools) and select 5 (Work with system parti-
tions), then 3 (Work with partition configuration), and assign the host partition for
the guest by entering 13 in the field next to the partition name.
• Declare a memory range for configuration in the LPAR (Logical Partition). This
is the minimum and maximum amount of memory assigned to this LPAR without
a primary IPL (Initial Program Load). The settings for the maximum amount should
also reserve space for the Hardware Page Table (HPT). However, having
too large of a maximum memory would cause a larger hardware page table to be
allocated from the partition's memory, reducing the amount Linux can use.
To calculate the memory available to an LPAR, use this formula:
("Configured Memory" minus "Maximum Memory of the LPAR Configuration")
divided by 64
The result is rounded up to a multiple of 2.
Example: The maximum size should be 248 MB. Assuming 1/64 of this value to
be taken up by the HPT, the result of 3.875 MB is rounded up to the value of 4 MB.
• Minimum memory requirements must be met. For a text-based installation, assign
the LPAR at least 256 MB. An installation with VNC requires at least 448 MB.
Assigning Network Storage Space
Next, assign SUSE Linux Enterprise Server some storage space. Do this with the utility
CRTNWSSTG.
