Figure 7: Initial GiCAP configuration (partial outage example)
Imagine that partition db1 has crashed, and the system administrator knows it will be hours or days
until the problem can be fixed. The application running in partition db1 is critical to the business and
must continue running on Server 2. The administrator chooses to seize usage rights from partition db1
to free up usage rights for Server 2.
The rights seizure command does not allow specification of the number of rights to be seized; the
command seizes all available core usage rights from db1, leaving behind one core usage right for
each cell that will be active on reboot. In this case, there are two cells configured to be active when
db1 reboots, so the rights seizure operation will extract six core usage rights and leave two core
usage rights with the db1 partition. The command to seize the rights is run on the Group Manager:
ap1> icapmanage -x db1
The seized usage rights are available to be migrated to other partitions, under control of the Group
Manager, as shown in Figure 8.
