Addition of the Freed Memory to vpar2
1 GB of available memory is added as floating memory to vpar2 using vparmodify. The output of
vparstatus shows the PASS state of the memory addition operation with sequence identifier 1. As
described earlier, the sequence id is unique within each partition and not across partitions. Hence,
both vpar1 and vpar2 in this example happen to have the same sequence id number. Once
completed, the output of vparstatus shows that the partition has 2 GB of base memory and 2 GB of
floating memory. The GlancePlus Memory Report below confirms that the free memory has increased
to 921 MB and the paging to swap space has stopped after the online addition of memory. The EVM
logs show the detailed progress of the memory online addition operation to add 1 GB of memory
starting at the physical address 0x150000000.
