HP Instant Capacity release notes for Version 10.x (March 2011)

Changes in Version 8.03 from Version 8.02.01 (HP-UX)
Support for vPars A.03.05 on HP-UX 11.11
iCAP version 8.03 included support for vPars A.03.05, and support for the “integrated virtual
partition environment” on HP-UX 11.11, previously available only on HP-UX 11.23 and 11.31
systems. With this release, vPars A.03.05 became the minimum required version. Support for vPars
version A.03.05 integration on HP-UX 11.11 systems allows users to manage 11.11 and 11.23
vPars with the same vparmonitor. In addition, what had been previously called the “compatible
virtual partition environment” is no longer supported on HP-UX 11.11 systems.
The vparmodify and vparcreate commands are now bound by the containing nPar's intended
active core count. Also note that in an integrated virtual partition environment, a boot time
compliance check is performed whenever a virtual partition is booted. If the total number of cores
assigned to all virtual partitions in the current vPar database exceeds the nPartition's intended
active core count, the Instant Capacity software notifies the vPar monitor, and the monitor prevents
any virtual partition from booting. See “Instant Capacity Integration with Virtual Partitions” in the
Instant Capacity user's guide for more details. With this release of Instant Capacity, the compliance
checking will now be performed on HP-UX 11.11 vPar systems, as well as 11.23 and 11.31
systems.
Changes in icapstatus output
The format of the date displayed by the icapstatus command was changed to facilitate
translation. Also, the format of the iCAP version number has been changed to provide more
information.
Improvements in translated messages
Several corrections were made to the Italian and Spanish message catalogs.
Changes in Version 8.02.01 from Version 8.02 (HP-UX)
GiCAP Disaster Recovery
iCAP version 8.02.01 included implementation of GiCAP Disaster Recovery, which enables the
distribution of core usage rights from a GiCAP member which is offline due to some disaster, to
other members of the group, and the restoration of usage rights to the member once contact has
been restored.
To support Disaster Recovery, the icapmanage -x option was expanded to allow the transfer of
usage rights not just from single unreachable partitions, but also from members which are completely
unreachable. In the case of unavailable group members, the transfer is limited to a specific time
period of 10 days.
A new option, icapmanage -z, was added to allow users to restore previously seized core usage
rights to a specified host. See the descriptions of the -x and -z options on the icapmanage
manpage for complete details.
NOTE: The Group Manager must be running iCAP version 8.02.01 or later, and all known hosts
on the complex containing a failed group member must be running iCAP version 8.02 or later, in
order to enable full Disaster Recovery features.
Changes in Version 8.02 from Version 8.01.01 (HP-UX)
Changes Relating to System Compliance
The iCAP software uses the debiting of Temporary Capacity to track the noncompliance of a system,
such as when there are more cores active than there are core usage rights on the system, even if
the system has had no Temporary Capacity applied to it. So, temporary capacity can be negative
