Hi,

On a z196 you can add a logical processor without deactivate/activate the
Lpar but z/OS must be at least on 1.10

This can be done via HMC

- Select the LPAR
- Operational Customization
- Logical Processor add
- change the reserved processors column accordig to your needs
- klick on "change running system"

After that you must configure the processor online in z/OS with the CF
command.

This should work for you. I've done that several times in the past.

Ralf

In order to follow z196 Technical Guide, chapter "3.4.9 Reserved
processors" of the book says:

 "Reserved CPs can be defined to a logical partition dynamically to allow
for nondisruptive image upgrades"

-- I understand that first you must have defined the *n* reserved
processors you might want.

Yesterday I defined initial the zIIP so the engine must be online after
IPL, but operations staff only does activate over the lpar so this morning
the engine wasn't available.

My question is in the other hand if you define reserved processors if is
needed to deactivate/activate the lpar as on initial engines.
