Implications of Removing a Cell from an
Instant Capacity System
The Instant Capacity software tracks the expected number of inactive
components (processors, cells, and memory) in a complex and knows the
actual number of active and inactive components. The complex is in
compliance if the actual number of inactive components meets or exceeds
the expected number of inactive components.
The complex is out of compliance if the actual number of inactive
components is less than the expected number of inactive components and
no temporary capacity exists.
However, a complex can also get out of compliance if a cell is removed
from the complex. For example, if a cell contains inactive processors that
are contributing to compliance, and the cell is removed, it is possible that
the complex is out of compliance and temporary capacity begins to be
debited.
Example A-1 Removing a Cell and Decreasing the Actual Number of Inactive
Processors
For example, a complex contains two cells, with two partitions having
two unlicensed and two active processors each. The Instant Capacity
software expects the complex to have four inactive processors. If one of
the cells (0) experiences a hardware problem, and you remove the cell,
the complex is left with only one cell that contains two active and two
inactive processors. The complex is now out of compliance because four
inactive processors are expected to be in the complex, yet there are only
two inactive processors.
