The specified host network address already exists

I'm using Dell CSI Unity driver with OKD 4 to provide storage via iSCSI and NFS. We are also using a Machine Config Operator so that cluster nodes can be provisioned, added, and removed easily. So far, this has worked OK and the new nodes get CSI unity-node pods scheduled on them.

Today we ran into a case where an IP address belonging to an old node was reused by a new node, and this has resulted in errors when the unity-node pod starts on that node.

The relevant log lines seem to be:

Hi @jgazeley

In the Array, Old node's host entry has to be cleaned up manually as the driver is not responsible for deletion of host entries. If an old node entry is cleaned up then you will not face this error.

Kindly follow the steps to delete the Old node's entry from Array:

1. Login to Unisphere/Array.
2. Go to hosts section.
3. Search for old host entry.
4. Delete old host entry.

Kindly try it out and let us know any issues further.
