(4) How to reactivate an LPAR
Open the Logical Partition Configuration screen. Move the cursor over the Sta
column of the LPAR row that you want to reactivate, and press Enter. Move the
cursor over Reactivate on the displayed subscreen and press Enter.
This reactivation operation works only on LPARs that are activated.
LPAR reactivation is equivalent to server restarting. Caution is necessary in
performing this operation especially if performed during data access (such as
starting a guest OS). Because a disk might be damaged, we recommended
restarting the guest OS instead of reactivation.
When rebooting the guest OS in operation on an LPAR,

the guest OS might hang up in the final process. If the
guest OS hangs up, reactivate the LPAR. The disk will
not be damaged because the LPAR has been
disconnected from the disk.
(5) How to change the number of shared processors to allocate to an LPAR
Standard server blades with LPAR manager firmware 58-2X or earlier
versions/High-performance server blades with LPAR manager firmware 78-2X or
earlier versions
Open the Logical Partition Configuration screen. Move the cursor over the Shr
column of the LPAR whose number of shared processors you want to change, and
press Enter. This will open a subscreen where you can select the number of
processors. Enter the desired number of processors, and press Enter. The number
of shared processors can be changed only when the relevant LPAR is inactive
You can assign the number of logical processors the same as
or less than that of physical processors available in shared
mode to an LPAR in shared mode. If you assign more logical
processors than physical processors to an LPAR in shared
mode, performance might extremely slow down.
It is recommended that the total number of logical processors
assigned to an LPAR in shared mode should be four times or
less than the number of physical processors available in
shared mode.
(6) How to change the number of dedicated processors allocated to an LPAR
Standard server blades with LPAR manager firmware 58-2X or earlier
versions/High-performance server blades with LPAR manager firmware 78-2X or
earlier versions
Open the Logical Partition Configuration screen. Move the cursor over the Ded
column of the LPAR whose number of dedicated processors you want to change,
and press Enter. This will open a subscreen where you can select the number of
processors. Enter the desired number of processors, and press Enter. The number
of occupied processors can be changed only when the relevant LPAR is inactive.
