Unable to Increase DataStore size even though there is space on SAN Volume ESX 6.5 5969303

Increase volume size on Dell Compelent SAN to say 18TB.

ESX Server(s) see the increase after rescan.

As does vCenter.

However, when you try to increase the datastore that is mapped to this it either says there are no devices with free space:

Or on the local ESX machine it shows up, but only once after an increase and errors with this:

Dell looked at this on both the SAN side and the Dell Server side.  they think it's some kind of bug in the VMware (VMFS6) drivers.

Any ideas appreciated.

Can you rescan all storage adapter and try. It seems like a client refresh issue .

Thanks, but I've done all the standard things like rescan etc.

Wondering if anyone else has hit a problem like this with 6.5?

First of all check the version of Host client you use and update it to the latest available version ESXi Embedded Host Client

As well you can try to increase VMFS manually from CLI Expanding a VMFS Datastore

If this doesn't help, we need to look deeper with some CLI commands and logs.
