Previously, validation would prevent self-ip from being deleted, if the self-ip could possibly strand a pool member.
You will be unable to delete the self-ip address. Mcpd will throw an error "Cannot delete IP 10.10.10.1 because it would leave a pool member (pool /Common/mypool) unreachable."
Deleting a self-ip, and the self-ip could be use to reach an existing pool member
Use one of the following workarounds: 1. Delete the pool member first, and then delete the self-ip 2. Change the self IP Netmask to 255.255.255.255 and then delete the self IP
It's possible to delete a self-ip that have the same network as a pool member, which will throw a warning instead, where previously it was preventing the deletion from happening.
