main storage & pool sizes
Hi
Installing a new I5 system (I520) with V5R4M00,
I find that the sum of all active pools is about 5.5 GB,
While the machine main storage is 6 GB.
Where is the missing half GB ???

This is hard to answer from a removed distance. I kind of doubt that anything has been lost. Can you give us a snap shot of the Wrksyssts with a view of the memory? Sometimes it just doesn't look like it adds up or maybe you have set aside memory for a pool you are not using. I haven't set up a new system with 5.4 but I have upgraded 2 systems to 5.4 and I have not seen this. In the old days 5.2 and before the excess memory always went to the Base pool and it was semi difficult to make memory unavailable.

Hi,
bellow is a snapshot of “Work with Shared Pools”
(all allocated pools at the time snapshot was taken)
Notice that Main storage size is 5.6 GB…

Whie Displaying Main Storage Information (service tool)
we can see 6 GB operational…

Have you checked your LPAR settings on the HMC? The main storag edisplay will always show the total memory installed on the system but the memory maynot be assigned to the LPAR.
Also the Hypervisor does take some memory but it should be the 256-512k range.
Hi
Checking the LPAR on SST I got this picture:
Display Partition Configuration
Partition identifier and name . . . . . . . : 1
Number of partition processors . . . . . . . : 1
Minimum / maximum number of processors . . . : 1/1
Use shared processor pool . . . . . . . . . : No
Size of partition memory (MB) . . . . . . . : 5696
Minimum / maximum size of memory (MB) . . . : 160/6144
Enable workload management . . . . . . . . . : No
…
Now I can see where is the missng half GB
Is it possible to chang partition size to be maximum size ?
If it is a single partition system then you shoul put the all of the memory in the Maximum filed but the hypervisor is still going to take a block so you’ll never see it all.
