Shutting Down a Partition with Instant Capacity Processors
Appendix A 129
Shutting Down a Partition with Instant
Capacity Processors
The Instant Capacity software saves information about the number of
active processors 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
processors in the inactive partition are active. See “Assumed Values in
icod_stat” on page 120 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
option with the shutdown command
• If the partition crashes or shuts down abnormally, reboot the
partition within 12 hours or power it down
IMPORTANT Always use the shutdown command when shutting down or rebooting an
Instant Capacity partition. See the manpage shutdown (1M) for
information on the shutdown command.
