Note for the LPAR manager operation

LPAR manager boot up

Please do not boot the multiple LPAR managers whose configuration have not
been made and whose firmware version are 01-1x, simultaneously. When
multiple LPAR managers are booted simultaneously, the failure which LPAR
manager hangs up might occur on initializing LPAR manager display.

LPAR Memory Fragmentation

When you repeatedly activate and deactivate LPARs with different memory
size on LPAR manager firmware version 01-1X or lower, a message "Memory
allocation failed (Fragmentation)." appears and an LPAR may fail to be
activated even if the memory size is enough. This is called "LPAR memory
fragmentation", which occurs in activating an LPAR that requires
discontinuous blanks of memory on physical memory. A typical example is
shown below.
Example 1:
Failure in LPAR activation due to LPAR memory fragmentation
(LPAR activation fails when 5 or more discontinuous blanks of memory are
allocated to an LPAR)
