Hi, all: In ACS web GUI, on the Pod Details page, the fields “Start IP” and “End IP” are editable. This IP range is reserved for systemVM’s (SSVM/CPVM). When I built my ACS environments three years ago, I gave this a large range without fully understanding what it is for. Now I am short of IPs on the management network, I would like to reduce this reserved range so that I can use some extra IP for other things, like more hypervisor hosts!
When I try to trim some IP off either end, I get an error message: “The specified pod has allocated private IP addresses. So its IP address range can be extended only”, even though I know for facts that my system VM’s are not using any of the IP’s that I am trying to free up. So, I did the obvious thing: disabled the zone, and deleted all the SSVM and CPVM’s. I even restarted the management service. However, when I try again to edit “Start IP” and/or “End IP” fields on the Pod details page, I still get the same error message above, even though now I have zero system VM! This does not seem to be correct to me. I guess, at this point, my only solution is to do direct DB modifications. Can someone please tell me which table contains this information? If any of you have successfully modified pod start/end IP without going direct DB hacks, please share your approaches. Thanks Yiping
