HP Instant Capacity User's Guide for Version 9.x

A.1 Assumed Values in icapstatus Command
The icapstatus command might make assumptions on the number of active cores and amount
of active memory, depending on certain system conditions. If values are assumed, the
icapstatus command output contains an asterisk next to the appropriate field.
A.1.1 Assumed Processor Values
Occasionally, the output of the icapstatus command contains an asterisk (*) next to the value
in the Actual Active Cores field (under the section Allocation of Instant Capacity
Resources among the nPartitions). The asterisk appears in the output whenever a
nonlocal partition appears to be active, but the icapd daemon is not reporting system information.
Some examples that can cause this situation include:
• The absence of a compatible version of the Instant Capacity software on a nonlocal partition
• No space left in /var on the nonlocal partition prevents icapd from communicating system
information
• A nonlocal partition shut down for an extended period of time with shutdown or reboot,
without the -R -H options (which brings the cells to an inactive state)
• A nonlocal partition running an operating system that is not HP-UX or OpenVMS (for
example, Windows or Linux)
In these cases, the Instant Capacity software on other partitions identifies all cores in the nonlocal
partition as active. In addition to the asterisks in the output of icapstatus, this can affect the
following:
• Temporary capacity consumption
• The ability to change the complex with parmodify, parmgr, or parcreate commands
• Core activation with the icapmodify command
• System noncompliance
NOTE: The number of active cores is always known for a local partition.
If a nonlocal partition appears to be inactive, the number of active cores reported by the
icapstatus command is zero. For example, if the hardware for a nonlocal partition is inactive,
icapstatus considers the partition as inactive and reports the number of active cores as zero.
A.1.2 Assumed Memory Values
When a cell board is powered off, regardless of whether the cell is in the local partition or in a
nonlocal partition, the amount of inactive memory is assumed to be 2 GB and is reported as such
by the icapstatus command. If the amount of memory without usage rights configured for
the cell exceeds 2 GB and the cell is powered down and remains assigned to the partition, the
system goes out of compliance.
An asterisk (*) might appear next to the value of the Inactive Memory field in the icapstatus
output, in the section Allocation of Instant Capacity Resources among the
nPartitions.
