Re: LPAR on a 520 -- MIDRANGE-L

Assuming enough resources currently exist, primarily RAID and LAN cards, yes.

Use STRASPBAL to drain the data from all the drives you wish to put into the second Partitoin. This will get them down to 1 or 2 % full then IPL to DST and remove them from the ASP. Now they are available to be attached to the new partition. Once properly partitioned IPL from tape or DVD to install to the now empty disks. RAID will already be in place (OK..... Assuming RAID in use today!) so the initialize of the load source disk will be slow, however you won't need to start RAID so it's a wash.

is it possible to split the current system into 2 LPARs with out unloading

Assuming you add the correct hardware there is no need for a reload here.
Just allocate the current disks to one partition and use the new ones for
another partition. That's the simplest and the memory and processor would be
allocated as you say. Certainly there are many other ways to move the disk
around as well but normally the current disk becomes one of the partitions.
You will likely want to swap the console on that partition to HMC but it's
not mandatory to do so. The new partition will need to be loaded from tape
or DVD and your choice there will depend on if you want to start with clean
IBM i or if you want a duplicate of the current partition as a starting
point.

Customer has a 9406-520 Feature code 7734 V5R4. The customer is inquiring

about adding a new LPAR to the system to be used as a production
environment. The current environment has been on the system since day one as
a single LPAR. The customer wants to divide the current system in half,
giving each LPAR half of the processor, memory and disk.

To convert the system this way, will I need to back up the old system, add

the hardware, create the LPARs and then reload the necessary data to the
correct partition?

Or can I add the hardware and the create the LPARs by dividing the system

resources to the correct partition using an HMC?

Any resource material on this type of conversion will be greatly

appreciated.
