5486wrkperf.fm Draft Document for Review October 18, 200448 IBM Eserver i5 and iSeries System HandbookProcessors activated solely for Linux, AIX 5L, or both do not require an OS/400license entitlement.To enable permanent activation of the inactive processors, a quantity ofactivation features and license entitlements is ordered. IBM manufacturing thengenerates an activation code (capacity key) unique to the server and the requiredadditional OS/400 license key or keys. The activation code is mailed to thecustomer and is posted at the following Web site:http://www.ibm.com/servers/eserver/iseries/ondemand/cod/The OS/400 license key is mailed to the customer and is posted on the Web at:http://www.ibm.com/servers/eserver/iseries/wwkmsRefer to “OS/400 terms and conditions changes” on page 601 for moreinformation about OS/400 and license entitlements.On/Off Capacity on Demand (temporary capacity)On/Off Capacity on Demand is the iSeries offering to temporarily activatecapacity and memory. Temporary capacity can be turned on and off to matchpeak periods. It allows a variable number of days and processors to be requested(processor days). The capacity is effective immediately. An IPL is not required.Before requesting temporary capacity on the server, the server must be enabled.To do this, an enablement feature (Miscellaneous Equipment Specification (MES)only feature) must be ordered and the required contracts signed. An enablementcode allows up to 360 processor days of temporary capacity for the Eserver i5550, 570 or 595 server, or 192 processor days on other servers.This means that requests for temporary capacity can be made over the life of themachine as long as the processor day limits are not exceeded. When the limit isreached, a new enablement feature must be ordered, and a new enablementcode entered. Every time a new enablement code is entered, the limit ofprocessor days that can be requested is reset.When temporary capacity is needed, the OS/400 temporary capacity screen onthe server is used to specify the number of inactive processors that are requiredto be temporarily activated, and the number of days. That is, the processor day isequal to the number of processors multiplied by the number of days. Theactivated processors simply need to be assigned to a partition prior to use,regardless of whether the server is configured for LPAR. Activating additionalprocessors does not require any additional OS/400 license entitlement to bepurchased for the temporarily activated processors.
