HP-UX vPars and Integrity VM V6.1.5 Administrator Guide (5900-2295, April 2013)

on the VSP OS using the icapmodify command and then execute the vparmodify command
to complete the activation of the cores on the vPar v6.x guest OS. Similarly, for a deactivation
operation, execute the vparmodify command on the vPar v6.1.5 guest OS and then execute
a icapmodify command on the VSP OS.
iCAP commands issued from the OA activate or deactivate cores only in the VSP. vparmodify
commands have to be issued in the VSP to move the core to and from a vPar v6.1.5. If there
is only one core in the VSP and the rest assigned to vPars a deactivation request from the OA
will fail.
TiCAP is consumed once the core is active at either the VSP or vPar v6.1.5. If TiCAP is being
used, to stop consuming TiCAP, the core must be deactivated from the vPar v6.1.5 as well as
the VSP.
