The icapstatus command provides the following temporary capacity information:
Amount of temporary capacity remaining (in days, hours, and minutes)
Number of cores using temporary capacity — this is the number of active cores without usage rights
Projected temporary capacity expiration date and time — this is based on the current temporary capacity consumption rate
You can find this information in the Instant Capacity Resource Summary section from the icapstatus command’s output.
Here is an example of temporary capacity information, from the Instant Capacity Resource Summary section of the icapstatus command’s output:

Temporary Capacity Expiration Reminder
The Instant Capacity software calculates when the temporary capacity balance will expire, based on the current consumption rate. After the temporary capacity balance reaches a certain residual number of days (see “Temporary Instant Capacity Warning Period”), a reminder e-mail message is automatically sent to the system-contact, if one is specified, and root. These messages will be sent on a daily basis until temporary capacity has expired. Here is an example of a temporary capacity expiration reminder e-mail message:
Example 5-4 Temporary Capacity Expiration Reminder
To: root@par1.yourorg.com
Subject: Temporary Capacity Expiration Reminder
***************************************************************************
**** Failure to perform the following steps will result in the complex ****
**** attempting to deactivate cores on any booting partitions until ****
**** the complex is in compliance with the Instant Capacity contract. ****
***************************************************************************
This message is being sent to remind you that your Instant Capacity complex
(containing the partition krmt10b) has 3 cores currently consuming temporary
capacity (TiCAP) and that the temporary capacity balance at the current consumption rate is projected to expire on or around:
05/31/05 16:00:00
You can view the current temporary capacity balance and consumption rate,
by using the icapstatus command.
To adjust the number of calendar days to receive the temporary capacity
warning before temporary capacity actually expires use: icapmodify -w
Before the temporary capacity balance runs out, you must perform one of the following steps:
1. Purchase additional temporary capacity and apply the temporary
capacity codeword to the complex.
2. Deactivate cores until the number of inactive cores on
the complex matches the number of cores without usage rights,
reported by icapstatus.
3. Purchase additional core usage rights to match the number of cores
currently consuming temporary, and apply the Right to Use
codewords to the complex so that they can be permanently activated.
See the Instant Capacity User's Guide at /usr/share/doc/icapUserGuide.pdf
for more information.
Also note that the output from icapstatus during the warning period includes a warning about the expiration of temporary capacity.
