User's Manual

A standby Group Manager can be added anytime after the
active Group Manager has grouping rules installed on it
(before or after the application of sharing rights to the
active Group Manager, before or after groups are created).
A Group Manager in standby status can be removed at
any time.
-T <host>[,<host>]...
Test hardware compatibility for one or more host systems
in order to determine which groups the systems can join.
When used with the -g option to specify a group name,
tests whether the specified host systems have hardware
compatible with the group. Without the -g option, report
which of all the groups managed by this Group Manager
have hardware compatible with the host systems. A host
can be specified using either the IP address or the name of
the host. The host names do not have to be from the same
complex, but to best predict the possibility of joining a
group, the list of hosts should include all the nPartitions
for a particular complex. If the hosts are not compatible,
no groups are reported as having compatible hardware.
-U <rule_file>
Specify the filename of a rule file.
Status Information
This section describes the fields that might be displayed when icapmanage -s is used to show
status. The exact choice of options used in combination with the -s option determines how much
of the information is displayed.
First, the display shows the software version number of the Global Instant Capacity software
and the current date and time. This is followed by the identification information for the Group
Manager: serial number, nPar ID (if any), and vPar code (if any). This identification information
is necessary when requesting a sharing rights codeword from the portal. Next, the Group Manager
status (active or standby) is displayed. On an active Group Manager, this is followed by the name
of the dedicated standby Group Manager (if any). On a standby Group Manager, this is followed
by the name of the associated active Group Manager. Next, the display shows the number of
sharing rights that have been purchased and applied to this Group Manager, and how many
sharing rights are currently in use versus the number still available to accommodate addition of
new members or new groups with new members.
Symbols used in the display
The output of the icapmanage -s command uses symbols next to the value of some fields in
certain circumstances. These symbols are as follows:
* Indicates an estimated number of active cores, memory or cells, because full information is
not available (for example, when a host is not reachable, or on some platforms when cells
are powered off).
# Indicates that all cores in the partition, rather than any specific number, have been requested
to be active. The number indicates the current number of cores in the partition.
Information displayed for each GiCAP group
These values can be displayed for each group managed by the Group Manager.
Group <group_name>: This field displays the name of the GiCAP group.
Group Members: This summarizes the name of each member in the group, and also shows
the host names comprising each member complex.
