Hi Yiping,
Which hypervisor do you use? Keep in mind if you use VMware then every VR will
also get an IP address in this same range – hence you need to have enough IP
addresses to cover all your networks, VPCs and SSVM+CPVM.
If you want to check in your DB the management IP range is defined in:
- host_pod_ref.description: think this is cosmetic
- cloud.op_dc_ip_address_alloc: row per IP address – and you have to reference
“nic” and “reservation_id” back to the “nics” table and from there reference
the “vm_instance” table.
Something like this should work – but double check it please – this was just
quickly thrown together:
SELECT
cloud.op_dc_ip_address_alloc.id,
cloud.op_dc_ip_address_alloc.ip_address,
cloud.op_dc_ip_address_alloc.pod_id,
cloud.op_dc_ip_address_alloc.nic_id,
cloud.nics.network_id,
cloud.vm_instance.name
FROM
cloud.op_dc_ip_address_alloc
LEFT JOIN
cloud.nics ON (cloud.op_dc_ip_address_alloc.nic_id = cloud.nics.id
AND cloud.op_dc_ip_address_alloc.reservation_id =
cloud.nics.reservation_id)
LEFT JOIN
cloud.vm_instance on (cloud.nics.instance_id = cloud.vm_instance.id)
WHERE
cloud.op_dc_ip_address_alloc.reservation_id IS NOT NULL;

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
