After attempting to delete an IP-Subnet in use within an IP-Pool, the IP-Pool is in a failed state, reporting it "cannot be updated because it has allocated IDs."

Products

• VMware NSX

Issue/Introduction

• You wish to expand the IP-Subnet range in use.
• Attempting to edit the existing subnet fails with the message "Range [{0}-{1}] cannot be updated because it has allocated IDs."
• You attempt to delete the IP-Subnet from the IP-Pool, which results in the IP-Subnet becoming uneditable (still in the interface but grayed out) and the pool reporting “Failed: Range [{0}-{1}] cannot be updated because it has allocated IDs.” 
  

Environment

VMware NSX

Cause

An IP-pool / IP-Subnet with allocated IP addresses cannot be edited. Attempting to delete an IP-Subnet range that is in use will succeed in getting it marked for deletion, but it cannot be resolved due to IPs being allocated.
