With cloud storage backing PX volume, will replica=1 volume failover to another PX node?

Given following:

I’m using PureStorage FlashArray LUNs as the backing storage for drives in a PX pool.
A replica=1 (non-HA) portworx volume is created.
When the k8s node dies/shutdown, is the PX volume expected to automatically failover to another node?

The automatic failover used to happen with PSO but we are not seeing this behavior with Portworx so trying to find if this is supported or only HA px volumes tolerate node failure?
