Control over activation of every defined LPAR has been available in the 'RESET' or POR profile since the first 9672 of the mid 90s. A trap that's easy to fall into, whenever customizing or editing the POR profile, is the HMC's generous offer to synchronize the activation set with the list of all defined LPARs. The assumption is clearly that you have inadvertently omitted an LPAR from the list. Maybe you have. Or maybe you have extra LPARs defined for whatever reason: testing, DR, future plans. You must resist the tempatation to let the HMC 'save' you. Activated LPARs *will* use memory to the detriment of any desired LPAR further down the activation sequence. Once all the memory has been meted out, any left standing in line will be toast.
An interesting question is the degree, if any, to which all defined LPARs whether activated or not actually consume HSA storage. That is, if you have one or five or ten LPARs defined, will HSA as some point increase simply by virtue of those LPARs' existence regardless of whether they are ever activated? If they do, then it would be accurate at some level to accuse them of tying up memory. But I can guarantee that--to the byte--an LPAR takes no storage whatever after POR if and until it's activated.

On the "Partitions" tab of the Reset Profile, you specify the order in which the partitions are activated. If no order is specified for a partition, it is not activated. That makes sense! Simple! We didn't have the option on the z/900's of three years ago. I assume/hope it's in the z/890, z/990, z9, and whatever is due to be announced? - -teD ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
