Comment 27 for bug 1994521

verified for jammy

deployed 3par simulator and simple cinder & cinder-three-par env.

I should replace hpe3parclient with latest one as there was error with ssh(deprecated)

After setting up, I created v1, s1, v2, s2 and tried to remove s1

It shows proper error msg like below

2024-05-10 07:00:31.234 98954 ERROR cinder.volume.manager [req-e920c633-4c10-47bd-8064-c95501512b8c a9790e787e5c4546b2513bd8f0ad7ca1 466ef0a6049743fb94433d698e4feffd - - -] Delete snapshot failed, due to snapshot busy.: cinder.exception.SnapshotIsBusy: Snapshot has children and cannot be deleted!
(previously, there was error and status is changed to error)

and snapshot status is still available
