HP Instant Capacity (iCAP) manual More cells active than expected

Example 9-1 Exception Report for More Cores Active than Expected

To: root@par1.yourorg.com

Subject: Instant Capacity Exception Report

This message is being sent to inform you that your Instant Capacity complex (containing the partition par1) is in an exception state based on the following detected exceptions:

More cores active than expected

This complex is out of compliance with the Instant Capacity contract. The listed exceptions must be corrected as soon as possible.

'More cores active than expected' means that the number of active cores across the complex exceeds the number of core usage rights. For details of core usage, use the icapstatus command. This exception state may be corrected by: deactivating cores until the number of inactive cores matches the global number of cores without usage rights, as reported by icapstatus. Alternately, additional core usage rights can be purchased for permanent activation, or temporary capacity (TiCAP) can be purchased and applied to the complex.

NOTE: When a system is in an exception state, many system management operations are likely to fail. These include, but are not limited to: the ability to activate cores, the ability to manage hard partitions (nPars), the ability to manage virtual partitions (vPars).

NOTE: One or more of the exceptions listed in this mail may be due to assumptions made because of an inability to get complete information (see icapstatus output for details).

In some cases, exception states arise when partitions are not shut down properly, or have been loaded without Instabt Capacity software. To eliminate these possibilities, do the following:

1)always use the "shutdown" command when shutting down a partition.

2)boot any partitions that may have been shutdown improperly.

3)ensure that all cells in the system are powered on.

4)ensure that Instant Capacity software is properly loaded and configured on all partitions.

NOTE: An exception related to cells, memory, or cores may occur if a cell containing inactive components is removed from the complex (e.g. for repairs or upgrades). Because Instant Capacity compliance requires that the number of inactive components on the complex must match the number of components without usage rights, you may need to adjust the number of inactive components on the complex if a cell containing inactive components is removed.

See the Instant Capacity user's guide at /usr/share/doc/icapUserGuide.pdf for more information.

As mentioned earlier, you can also receive an exception report for other exception conditions. Here are the other conditions and examples of the appropriate exception report content:

•More cells active than expected

'More cells active than expected' means that the number of active cells across the complex exceeds the number of cell usage rights. To find out how many inactive cells are expected on the complex, run icapstatus and look at the global number of cells without usage rights. This exception may be corrected by using parmodify to set the use_on_next_boot flag for an assigned cell to “n”, followed by a partition reboot. Alternately, cells may be
