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

Shutting Down a Partition with Instant Capacity Cores
The Instant Capacity software saves information about the number of active cores for each
partition and this information expires over time. If the partition is not active (but the hardware
is powered up), Instant Capacity software on other partitions assumes that all cores in the inactive
partition are active unless it can detect otherwise. See “Assumed Values in icapstatus” (page 170)
for details of these assumed processor values.
These are the general rules the Instant Capacity software uses:
• If the partition is to be shut down for less than 12 hours, no action is necessary
• If the partition is to be shut down for greater than 12 hours, consider powering the cells off,
or shutting the partition down using the -R -H option with the shutdown command
• If the partition crashes or shuts down abnormally, reboot the partition within 12 hours or
power it down
IMPORTANT: If you shut down a partition for 12 hours or more, you should also power it off
to avoid additional charges. To power off the partition, execute the PE command from the system
MP.
On HP-UX systems, always use the shutdown command when shutting down or rebooting an
Instant Capacity partition. See the HP-UX manpage shutdown(1M) for information on the
shutdown command.
On OpenVMS systems, always use the sys$system:shutdown.com procedure when shutting
down or rebooting an Instant Capacity partition.
