Acquiring and Configuring Temporary Instant Capacity

To add temporary capacity to a system that contains Instant Capacity cores (cores without usage rights), follow this procedure:

  1. Order the desired amount of temporary capacity for your type of server by submitting a purchase order to HP. You must specify the system serial number.

    After you purchase an amount of temporary capacity, HP sends you a letter that contains details on how to acquire a temporary capacity codeword and apply it to the system.

  2. Acquire the temporary capacity codeword from the Utility Pricing Solutions portal (http://www.hp.com/go/icap/portal)

  3. Apply the temporary capacity codeword using the icapmodify -C command:

    Example 5-1 Applying a Temporary Capacity Codeword (HP-UX)

    /usr/sbin/icapmodify -C vnyqD.qjieC7e.LaLdQGH.4aCNYBp-BQk3w9n.jfDhpvz.LiEB58C.7Q3dca2

    The following valid codeword has been applied to the complex:

         Temporary Capacity Codeword
         30 days 0 hours 0 minutes

    Use icapstatus(1M) to see the results of the application of this codeword.
    NOTE: iCAP codewords are based on both the serial number of a system and a unique sequencing value for that server. These codewords must be applied in the sequence in which they are obtained for a particular server. They can be applied to any partition on the server.
  4. Optional: if you wish to view temporary capacity balances on the portal, configure your partition for e-mail connectivity to HP. See “Configuring E-Mail on Instant Capacity Systems” for details.

Utilizing Temporary Instant Capacity

Auditing of temporary capacity is done at the complex level on Instant Capacity systems that support partitioning.

To use temporary capacity in a system that contains Instant Capacity cores, and has had the temporary capacity RTU codeword applied, follow this procedure:

To activate one or more cores in an nPartition, and allow them to use temporary capacity, use the icapmodify -t -a <number> command/options.

In the following activation example, two cores are currently active in the partition. You desire to activate a third core, but there are no available usage rights for activation. Because temporary capacity is available on the system, you can activate a third core with it.

Example 5-2 Activating an Instant Capacity Core with Temporary Capacity (HP-UX)

/usr/sbin/icapmodify -t -a 1 

3 cores are intended to be active and are currently active.

Number of cores using temporary capacity:                    1
Projected temporary capacity exporation:     7/22/06 08:00:00
NOTE: Temporary capacity cannot be used to activate Instant Capacity cores in inactive Instant Capacity cell boards. Additional usage rights must be purchased for the cell board, and perhaps also for the memory of the cell board.

When you want to decrease or stop using temporary capacity, you deactivate the appropriate number of cores. Note: you do not use the “-t” option when deactivating cores. Temporary capacity will no longer be used when the number of active cores is equal to or less than the number of cores with usage rights, across the complex.

To deactivate one or more cores in an nPartition, use the icapmodify -d <number> command.
