HP Instant Capacity User's Guide for Versions 8.x

Upgrades and Global Instant Capacity
Care must be exercised before upgrading or changing hardware for any member of a GiCAP
group. If a member of a GiCAP group changes hardware in such a way that the hardware is no
longer compatible with the group, then the group is considered to be out of compliance and
group functions are restricted.
Also, note that the number of available Sharing Rights is adjusted whenever an iCAP codeword
is applied to a GiCAP member system which modifies the number of cores without usage rights
on that member. (RTU and AddOn codewords for cores cause such adjustments.)
If available Sharing Rights go negative (more in use than were purchased for the Group Manager),
then all groups managed by that Group Manager are out of compliance and all group functions
are restricted until the problem is resolved. The problem can be resolved by purchasing and
applying additional Sharing Rights to the Group Manager, purchasing and applying core usage
rights (RTUs) to one or more group members, or by removing one or more group members from
their group.
When such an incompatibility is detected, the GiCAP Group Manager sends e-mail to the local
root account and to the registered contact e-mail address for each member of the group.
Adding New Partitions
When reconfiguring a member system by adding or deleting an nPartition, you may use the
icapmanage -u command to add or remove host names to or from the member. For example,
to add a new nPartition with hostname hostC to member memberA:
icapmanage -u -m memberA -h hostC
To remove a host name, prefix the host name with “!”, as in “!hostC”. You may also add or
remove a list of hosts; separate the additions from the removals with a “!”, as in
“hostA,hostB!hostC,hostD” to add hostA and hostB while removing hostC and hostD.
If the Group Manager is run on a partitionable system, changing the configuration of the partitions
may result in the Group Manager becoming inoperative. This is because the Group Manager
database is tied to the serial number of the complex, the nPartition id number and a virtual
partition id number. Although adding or modifying partitions will not change these ids, they
will be changed if a partition is deleted and recreated on the Group Manager.
