We see the three partitions in our block diagram now:
Note: When using vPars A.03.01 or earlier, I/O is assigned only at or below LBA level. For
correct I/O allocation, you must specify the LBA. With vPars A.03.02 or later, I/O can be
assigned at or below SBA level now.
Take always special consideration to core I/O devices owning the console hardware, when
creating and modifying vPar configurations. A good practice is to always include it in the first
vPar used. Taking this resource away from this vpar can cause a loss of console access.
On cell-based systems, the CPU path includes the cell number and should look like cell/CPU. A
typical vparcreate command would look like:
