Example 8 vPar Boot–Time compliance message
To: root@par1.yourorg.com
Subject: vPar Boot Time Compliance
This message is being sent to inform you that a vpar is not
being allowed to boot because doing so would take this complex
out of compliance from an Instant Capacity perspective. The
number of cores assigned to this vPar database (/stand/vpdb)
exceeds the number of intended active cores by 1. To correct
this problem, boot this partition back into an nPartition and
modify the vPars assigned to this database or modify the number
of intended active cores for this nPartition.
Assigning a cell to a partition
A cell can be assigned to a partition only if sufficient cell usage rights are available across the
complex, sufficient memory usage rights to enable activation of all the memory on the cell, and
sufficient usage rights for at least one core of the cell to be active.
In an iCAP system, when a cell is assigned to a partition, depending on the number of core usage
rights available in the system when the cell is assigned, the number of intended active cores for
the partition automatically changes. Figure 3, Figure 4, and Figure 5 illustrate a single partition
with one assigned and one unassigned cell.

When Cell 2 is assigned to the partition, the number of intended active cores for the partition is
automatically changed to 5. When the partition is rebooted, 5 cores in the partition are activated.
When an unassigned cell is assigned to a partition via the parmodify command, the iCAP
software determines the number of available core usage rights in the complex, and uses this number
to activate as many cores as possible in the new cell. (This number typically corresponds to the
