Re: LPAR on a 520

[DrFranken <midrange@xxxxxxxxxxxx>]

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.
