HP Instant Capacity Version 10.x User Guide (762794-001, March 2014)

icapmodify -d operation had been performed before
the specified hard partition stopped running. This makes
core usage rights available for potential loans to other
member systems. In this situation, the seized core usage
rights do not have an expiration date. However, because
there are other member partitions running iCAP software,
the unreachable partition may be assumed to be using all
cores on cells configured for that partition. Because of this,
cells in partitions from which usage rights have been
acquired should be rebooted or made inactive within 12
hours. If this is not done, the partition can begin to consume
temporary capacity. If temporary capacity is not available,
the complex might no longer be in compliance with the iCAP
contract. Cells can be made inactive by removing them from
the partition, shutting down the partition from within the OS
by using shutdown -R -H, or with the MP RR command.
If, at the time of rights seizure, all member partitions are
unreachable, the rights seizure is deferred and must be
viewed as a limited and immediate loan of usage rights
from the specified partition to the group. This loan of seized
usage rights expires in 30 days. Upon expiration, usage
rights are automatically restored to the member partitions
from which they are seized. The expiration date for a rights
seizure operation effectively terminates the period during
which the core usage rights are available to other group
members for purposes of disaster recovery. If none of the
member partitions are reachable by the expiration date for
a particular member, the usage rights are automatically
restored (reassigned) to the member partition (or complex,
in the case of unassigned seized rights) from which they
were seized. However, if the seized usage rights have been
redeployed to other members and are not released at
expiration time, the group might go out of compliance, or
temporary capacity might be used to maintain compliance.
If any partition of the inaccessible member from which rights
seizures were deferred reconnects to the group before the
expiration date, the seized core usage rights (for all
partitions) are finalized as a loan from the member to the
group, the expiration date is no longer relevant, and the
usage rights can thereafter be manipulated with normal
icapmodify operations.
While rights seizure operations can be performed in a virtual
partition environment, the rights seizure always operates
on, and affects, the entire nPartition. This means:
• Rights seizure can be performed only if all the virtual
partitions for an nPartition are down.
• For a given nPartition, you can specify any of the virtual
partition host names as the target of a rights seizure
operation or as the target of a usage rights restore
operation.
• Because rights seizure leaves only a minimum of core
usage rights with the nPartition, it is likely that the
remaining number of core usage rights is not sufficient
