Can't get the percent used of /bootbank with command df -h

The command df -h returns the below results...

VmFileSystem: SlowRefresh() failed: Cannot open volume: /vmfs/volumes/5575c5de-6ba7f495-302f-40a8f03b8228. Cannot open volume: /vmfs/volumes/5575c5de-6ba7f495-302f-40a8f03b8228Error when running esxcli, return status was: 1

Errors:

Error getting data for filesystem on '/vmfs/volumes/5575c5de-6ba7f495-302f-40a8f03b8228': Cannot open volume: /vmfs/volumes/5575c5de-6ba7f495-302f-40a8f03b8228, skipping.

The command: esxcli storage core device partition list

This returns some data but no usage numbers.

This an HP Gen9 running ESXi 6.0.0 7967664

I'm trying to get the amount used or percent used or percent free/available.....etc

The command df -h works perfectly fine on an HP DL360 Gen10 with the same ESXi version..........weird

Thanks
