HP Instant Capacity (iCAP) specification

Removing a Global Instant Capacity Group Member

Before removing a member from a GiCAP group, all the borrowed usage rights must be returned and all outstanding loans reclaimed. Do this by deactivating resources on the member about to be removed. Loaned usage rights are reclaimed by deactivating enough resources elsewhere in the group to cover the loan. The reclamation of loaned usage rights on the member about to be removed does not require the activation of resources on that member. As long as the usage rights are not in use elsewhere in the group, removing the member results in the member reclaiming its loans.

There is no constraint on temporary capacity because a removed member will take with it whatever temporary capacity is assigned to it.

When a member is removed from a group, some number of sharing rights are released and made available for future use. The number freed is equal to the number of cores without usage rights on the removed member.

The following commands remove member IT from its group, and then remove group one:

>icapmanage -r -m IT Member IT removed.

>icapmanage -r -g one Group one removed.

A group cannot be removed until all members in that group have been removed.
