Boot Time Compliance
A 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. The monitor
prevents any virtual partition from booting until the user first performs a hard partition boot and
then modifies either the vPar configuration or the Instant Capacity intended active count for the
nPartition.
psets on vPars
In a vPar environment, the Instant Capacity software passes the request for a core activation or
deactivation to the vparmodify command.
With vPars version A.04.01 or later, vPars is pset-aware to some extent. With vPars versions
earlier than A.04, no special consideration is given to psets from the vparmodify command’s
perspective.
TiCAP and vPars
If temporary capacity is being consumed in any virtual partition environment, deactivating a core
with the “vparmodify -d” command temporarily reduces the consumption of temporary capacity.
Use the “icapmodify -d” command to immediately decrease or cease the use of temporary
capacity.
LPMC Deactivations in vPars
In a vPar environment, if the LPMC monitor deactivates a core, it automatically replaces the
failing core with an Instant Capacity core from the free pool, if such a core is available. The
failing core remains in the virtual partition until either the virtual partition or the virtual partition
monitor is rebooted.
iCAP e-mail requirements
Instant Capacity version B.07.x and later no longer require email connectivity or asset reporting.
However, you can choose to configure it because it can be useful for viewing complex-wide
asset information at the Utility Pricing Solutions portal.
The root user or the system contact if designated receives the following types of email
notifications from the Instant Capacity software:
 Core activation or deactivation
