Can a faulty cell board be replaced with an inactive Instant Capacity cell board?
Yes. First, deactivate the failed cell board by using the parmodify command and rebooting. Then
activate the inactive iCAP cell board and reboot. In this situation, you do not need to obtain an
RTU to activate the cell board.

Does HP know the configuration of the GiCAP groups?
No. GiCAP group data is stored on the GiCAP Group Manager, which runs in the customer’s data
center. The group configuration is limited by HP grouping rules, but information about groups or
group members is not communicated to HP.
Is GiCAP migration supported on a completely unavailable server?
Yes. GiCAP Disaster Recovery is supported as long as the Group Manager is running Instant
Capacity version 9.0 or later, and all known hosts on member servers in the group are running
Instant Capacity version 9.0 or later.
How much history is retained in the GiCAP log files?
The GiCAP log files retain up to 2 MB of GiCAP events. Some example GiCAP events that might
be logged include:
• A GiCAP group is created or removed.
• A member is added to or removed from a GiCAP group.
• A member is updated through addition or removal of a host.
• A standby Group Manager is added or removed.
• A standby Group Manager takes control from the active Group Manager.
• A codeword is applied that modifies the available Sharing Rights.
• The grouping rules are replaced.
• Usage rights or temporary capacity is transferred between a member and the GiCAP Group
Manager.
You can view all events in the GiCAP log files in the /var/adm/gicap.log file on the Group
Manager system.
