DESCRIPTION

A Global Instant Capacity (GiCAP) group consists of a Group Manager system and one or more partitionable complexes which are the members. The primary purpose of a GiCAP group is to enable group members to share Instant Capacity usage rights (for cores, cell boards, and memory) and temporary capacity. A Group Manager has either active or standby status. An active Group Manager coordinates and monitors resource sharing, has had hardware grouping rules applied, and has had GiCAP sharing rights purchased for and applied to it. Optionally, an active Group Manager can designate as a standby Group Manager any HP-UX system that runs Instant Capacity software but has not itself had GiCAP sharing rights applied. The standby Group Manager has the ability to take control as an active Group Manager if the original active Group Manager should become unusable for any reason.

Because the members of a group are partitionable complexes and GiCAP must be able to contact all of the partitions, GiCAP members must be defined by specifying a <hostlist> to describe the host OS instances of all the partitions.

The symbol <hostlist> is a string of one or more host names or IP addresses with the form

<host>[,<host>]...

A host can be a vPar or nPar OS instance, but it cannot be a virtual machine (“guest”). When using HPVM on a prospective GiCAP group member, you must specify the name of the HPVM host OS instance, not the name of an HPVM guest OS instance.

The icapmanage command, which is used to create, manage, and remove groups, can be invoked only on a Group Manager system. On a standby Group Manager, only the -Qand -soptions are allowed, all other options are restricted to use only on the active Group Manager. The icapmanage command should not be invoked on a group member system.
