Global Instant Capacity Group Managers

For each group, an HP-UX system must be designated as the Global Instant Capacity Group Manager. It is this system which maintains information about the group, group resources, and the grouping rules. icapmanage commands are intended to be invoked only on a Group Manager system.

The Group Manager must be an HP-UX system running Instant Capacity version 8.01.01 or later software. The system running the Group Manager does not need to have any Instant Capacity components, nor does it need to be a partitionable system. A Group Manager cannot be run on a virtual machine (also known as a “guest”). The system must have a machine-readable serial number, as displayed by the command getconf CS_MACHINE_SERIAL.

The Group Manager may be run on either a partitionable or non-partitionable system. If run on a partitionable system, changing the configuration of the partitions may result in the Group Manager becoming inoperative. For optimal availability, it is recommended that the Group Manager be on a server separate from the member systems of the group. However, a Group Manager can manage multiple groups. The number of groups managed by a Group Manager has little to no impact on performance.
