I confirm shelving then unshelving the instance does do the trick:
1) Launched a volume backed instance and checked the connection_info
data in the database:
mysql> select connection_info from volume_attachment where
volume_id='132f6fb0-1119-4e8a-a555-18e4dfc8cbbf';
+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| connection_info
|
+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| {"name": "cinder-ceph-nvme/volume-132f6fb0-1119-4e8a-a555-18e4dfc8cbbf",
"hosts": ["10.1.15.222", "10.1.15.140", "10.1.15.138"], "ports": ["6789",

+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)
2) Artificially updated the records with invalid IP addresses:
mysql> update volume_attachment set connection_info='{"name":
"cinder-ceph-nvme/volume-132f6fb0-1119-4e8a-a555-18e4dfc8cbbf", "hosts":
["10.1.15.225", "10.1.15.142", "10.1.15.139"], "ports": ["6789", "6789",
"6789"], "cluster_name": "ceph", "auth_enabled": true, "auth_username":
"cinder-ceph-nvme", "secret_type": "ceph", "secret_uuid":
"1ffc33c5-d23d-4355-9297-f26aae327a49", "volume_id":

"access_mode": "rw", "encrypted": false, "cacheable": false,
"driver_volume_type": "rbd", "attachment_id":
"70405775-a24c-4235-a342-fdd0c64ece93"}' where
volume_id='132f6fb0-1119-4e8a-a555-18e4dfc8cbbf' limit 1;
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0
3) Shelved then Unshelved the instance, I see a fresh entry in the
connection_info table with the correct mon IP addresses:
mysql> select connection_info from volume_attachment where
volume_id='132f6fb0-1119-4e8a-a555-18e4dfc8cbbf';

4) Verified the instance is running and was able to SSH to it
