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)
Figure 10-1 Example 1 of Memory Fragmentation
When this problem has occurred, performing the following operations may
activate the LPAR. You can find the LPAR memory allocation on the physical
memory in the memory allocation display in the logical partition (LPAR)
configuration screen.
1
.
Change the memory size of an LPAR to activate to the size containing up
to 4 blanks of memory.
2
.
Deactivate those activated LPARs that are using memory next to blank
memory.
3
.
Define a dummy LPAR, specify smaller blanks of memory to the memory
size of the dummy LPAR, and then perform activation.
Note:
•
It is recommended that you should check blank memory allocation in the
memory allocation display to keep the number of discontinuous blanks of
memory up to 4 during operation.
