problems, the Group Manager should also be able to
contact any standby manager that is defined.)
NOTE: option "-u" is not supported on Sd2 systems.
-v Provide verbose status information. Include all levels of
information (group, manager and member). For Group
Managers, include resources being held by the Group
Manager including temporary capacity. For members,
include borrow and loan information and partition-specific
information, such as the allocation of resources among the
hard partitions, and partition-specific information about
seized or seizable usage rights (see icapmanage -x).
This option is ignored if the -b option is also specified.
This verbose option also attempts to contact every host of
each group member to check that two-way communication
can be established between the issuing group manager
(either active or standby) and each such host. The
icapmanage -s command without -v attempts to contact
multiple hosts on a group member only if that is necessary
to find a host that responds. In either case, icapmanage
-s reports which hosts it failed to contact. Use of the -v
option can be useful as a general health check of group
communication.
-x <host> Acquire core usage rights from the nPartition containing the
specified host to make them available to other group
members, also known as rights seizure. Rights seizure takes
almost all the available usage rights from the hard partition
containing the specified host. The specified host must be
known to the GiCAP manager (it appears in the output of
icapmanage -s) and not currently running. If other hosts
are associated with the same hard partition, they cannot be
currently running. The icapmanage -x operation can be
performed after for each hard partition on the member. For
confirmation, the icapmanage -x command verifies each
known host on the hard partition. The hard partition
containing the specified host is left with one core usage right
per active cell (For SD2 systems its leaves behind one usage
right per member complex). Any core usage rights in excess
of this amount becomes available for use elsewhere in the
GiCAP group. For example, if a partition of 2 cells is
currently consuming 6 core usage rights, icapmanage -x
<host> makes 4 core usage rights (6 - 2) available for
reassignment.
While rights can be seized from any hard partition that is
unavailable, the Instant Capacity software makes some
additional restrictions when all partitions of a complex are
unavailable. As a result, there are different behaviors and
constraints depending on whether or not a partition can be
contacted on the specified member complex.
At the time of rights seizure, if at least one member partition
can be contacted, the software is able to make an immediate
adjustment to the available core usage rights, as if an
