have you rebooted that host with MaintenanceMode active...?

Please double check that before unmounting there is no running VMs on the DS, its not SIOC enabled, its not used for HA heartbeats or its not part of DS cluster...also verify that non of your VMs is connected to some .iso file on that datastore...

If you have configured your DS for SIOC you can turn it off via shell:

/etc/init.d/storageRM stop



If non from above working you can try Reset ESXi system configuration to its deafaults from the DCUI...note that this will remowe any custom configuration data including passwords.
