To delete the assigned static IP addresses for your servers in UCSM, you can follow these steps:
1. Log in to the UCS Manager GUI.
2. On the left side navigation pane, click on the "Servers" tab.
3. Expand the "Servers" tree, and then expand "Service Profiles" to locate the service profile associated with the server for which you want to remove the static IP.
4. Right-click the service profile and select "Disassociate Service Profile" to disassociate the server from the service profile. This will revert the server to use its default IP address settings and will no longer use the static IP address.
5. After disassociating the service profile, you can now delete the static IP address from the service profile. To do this, right-click the service profile again and select "Modify Service Profile" or "Configure CIMC".
6. In the "Modify Service Profile" or "Configure CIMC" window, navigate to the Mgmt IP Address section or IPv4 Static IP section, and then delete the static IP address that you previously assigned.
7. Click "Save" or "OK" to save the changes, and then re-associate the service profile with the server.
Now, the server should use the IP address from the IP pool without any conflicts.
If you need to remove the static IP address for multiple servers or service profiles, you can use the same steps as above, but perform them for each server or service profile that has a static IP address assigned.
Please note that disassociating and re-associating the service profile might cause the server to reboot, so ensure you schedule a maintenance window for this task.
