4. The Managed System Server Property Dialog window is shown (Figure 14-30). You can
select any i5/OS partition to be the service partition, although it must be in an inactive
state to be added or removed. Also, only one i5/OS partition can be the service partition at
any given time.

5. Select the new service partition from drop down menu and click OK. If the partition you are
trying to add or remove is active you will receive message:
HSCL0235 - Cannot change service partition from one partition to another if either one of
them are not in the Not Activated states.
Verifying if an i5/OS partition is the service partition
You can check if an i5/OS partition is set to be the service partition from the output from
DSPPTF i5/OS command. In Figure 14-31 we can see an additional information for the IPL
source field. The ##SERV#T entry shows that this partition is the service partition and the
system is running on the t-side of the managed system firmware. Only the service partition
will show this information, all other i5/OS partitions will only show the normal ##MACH#B or
##MACH#A data.
