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.
For the LPAR manager firmware version 02-62 or later, the LPAR manager
system time is reset to 2000/01/01 00:00:00 when LPAR manager starts,
unless the physical RTC time is set within the range from years 2000 to 2099.
Then, the reset time is saved in the physical RTC. In the LPAR manager
system log, system event log, and HCSM alert, you can check that the LPAR
manager system time is reset.

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.

be 1024 x 768.
If a guest OS resolution is more than 1024 x 768,
the console terminal displays the area of 1024 x 768
out of the screen. But the screen can be scrolled by
