ESXi 6.7 and 6.5 will not see increased iSCSI volume

Working on upgrade planning for move from vSphere 5.5 to 6.7.  Using iSCSI storage (on a Pure Storage array.)  Discovered that ESXi 6.5/7 will not recognize a volume increase until the host is restarted.  Not an ideal workaround.  I don't see this behavior on ESXi 6.0, or 5.5, both which recognize the increase following a rescan of the storage adapter.  Has anyone else run into this?  Found a better workaround?

Steps to reproduce:

1. Install 6.5.0 Update 2 (Build 8294253) or 6.7.0 Update 2 (Build 13006603)
2. Install iSCSI Adapter and connect to storage
3. Confirm volume is shown in Storage→ Devices and the datastore (if applicable) under Storage→ Datastore
4. On Pure Storage array, increase size of the volume (say 500 GB to 1 TB)
5. On ESXi 6.5 host, Storage→ Devices→ Rescan
6. Observe no change in the "Capacity" column

Workaround:

• Restart host → Storage→ Devices→ observe "Capacity" column now reflects size increase
• Disconnect NICs used for storage → reconnect NICs →  Storage→ Devices→ observe "Capacity" column now reflects size increase
