esxi6 with fibre channel LUN says vmkfstools failed: vmkernel is not loaded or call not implemented

Hello everyone, new to this community so please bear,

Happy ESXi5.5 user here. Just installed ESXi6 in a server, plugged it via FC into my SAN (EMC Clariion CX3-40f) and tried to partition and format a 250Gb LUN. After trying it via the vmware console and having failed, I ssh'd to the server and tried to carry the partitioning and formating steps one by one. However, I still cannot format the partition:

[root@myserver:~] /sbin/vmkfstools -C vmfs5 -S LUN250GBFC /vmfs/devices/disks/naa.600601601f712100669db307a087e011:1
create fs deviceName:'/vmfs/devices/disks/naa.600601601f712100669db307a087e011:1', fsShortName:'vmfs5', fsName:'LUN250GBFC'
deviceFullPath:/dev/disks/naa.600601601f712100669db307a087e011:1 deviceFile:naa.600601601f712100669db307a087e011:1
ATS on device /dev/disks/naa.600601601f712100669db307a087e011:1: not supported
.
Checking if remote hosts are using this device as a valid file system. This may take a few seconds...
Creating vmfs5 file system on "naa.600601601f712100669db307a087e011:1" with blockSize 1048576 and volume label "LUN250GBFC".

       vmkfstools -C [vmfs5|vfat] /vmfs/devices/disks/mpx.vmhbaA:T:L:P
Error: vmkfstools failed: vmkernel is not loaded or call not implemented.

The interesting part is probably "Error: vmkfstools failed: vmkernel is not loaded or call not implemented"

I haven't been able to make sense out of this "vmkernel is not loaded or call not implemented" message. Note, this is a fibre channel CX3 Clariion SAN, so it should be enterprise enough for esxi's tastes. Plus, I have never had any trouble using esxi5.5 with the same SAN.

(When I tried via the vmware console, the operation failed with the message "ATS on device ... not supported", but judging from the additional output via the cli, I am not convinced this is the culprit. Plus, I actually issued "esxcli system settings advanced set -i 0 -o /VMFS3/HardwareAcceleratedLocking" but I still get the same error)

Any help will be much appreciated.

Athanasios

Note for anybody reading this thread in the future, this is not about ESXi 6. ESXi5.5 (tried both vanilla and the Dell flavor) exhibits the same behavior. I'll transfer my question to the general discussion.
