HP Instant Capacity User's Guide for Versions 8.x

Assumed Values in icapstatus
The icapstatus command may 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’s output contains an asterisk next to the appropriate field.
Assumed Processor Values
Occasionally, the output of the icapstatus command may contain 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
non-local 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 Instant Capacity versions 8.x software on a non-local partition
• No space left in /var on the non-local partition prevents icapd from communicating system
information
• A non-local partition was shut down for an extended period of time with shutdown or
reboot, and the -R -H options were not used (which brings the cells to an inactive state)
• A non-local partition is running an operating system that is not HP-UX or OpenVMS (for
example, MS Windows or Linux)
In the above cases, the Instant Capacity software on other partitions assumes that all cores in the
non-local partition are 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
• The system may not be in compliance
NOTE: The number of active cores is always known for a local partition.
If a non-local partition appears to be inactive, the number of active cores reported by the
icapstatus command is zero. For example, if the hardware for a non-local partition is inactive,
icapstatus considers the partition as inactive and reports the number of active cores as zero.
Assumed Memory Values
When a cell board is powered off, no matter if the cell is in the local partition or in a non-local
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
will go out of compliance.
An asterisk may appear next to the value of the Inactive Memory field in the icapstatus
output, section Allocation of Instant Capacity Resources among the
nPartitions.
