I have a Dell R610 running esxi5.5 trying to access a 250Gb LUN in an EMC CX3-40f Clariion array. The LUN is indeed visible, as I can myself see by issuing
~ # esxcli storage core device list .... naa.600601601f712100669db307a087e011 Display Name: DGC Fibre Channel Disk (naa.600601601f712100669db307a087e011) Has Settable Display Name: true Size: 256000 Device Type: Direct-Access Multipath Plugin: NMP Devfs Path: /vmfs/devices/disks/naa.600601601f712100669db307a087e011 Vendor: DGC Model: VRAID Revision: 0326 SCSI Level: 4 Is Pseudo: false Status: on Is RDM Capable: true Is Local: false Is Removable: false Is SSD: false Is Offline: false Is Perennially Reserved: false Queue Full Sample Size: 0 Queue Full Threshold: 0 Thin Provisioning Status: unknown Attached Filters: VAAI Status: unknown Other UIDs: vml.0200000000600601601f712100669db307a087e011565241494420 Is Local SAS Device: false Is USB: false Is Boot USB Device: false No of outstanding IOs with competing worlds: 32 ...
However, when trying to mount the LUN via the esxi console, I get an error. The vmkernel.log says:

Anybody knows what is the culprit?
The LUN is formatted, as I've been able to format it and mount it correctly to other esxi machines (Dell R620). Everything goes smoothly. So as far as I can tell, the only difference is that this server is an R610.
Thanks,

I am having the exact same issue. RAID6 (VRAID) everything is the same except my lun is 600G, and I am on a CX3-20f
Have you resolve this yet?
It seems as though once you have presented a LUN on a specific LUN # you cannot change that LUN. This problem started when I backed everything up and recreated a fresh LUN that was larger. I am no longer able to access it. I can access the Partition Table with partedUtil, I can even mount the raw disk to a windows box that is on a VM. But I cannot get VMWare to access the LUN and create the VMFS partition.
Any ideas at all?
Bad news is if I cannot get this fixed we will be moving away from VMWare to Hyper-V, because I cannot defend this behavior!!! ergh...
Hello,
Yes it is resolved, here's how: Re: Failed to open device naa.xxxxx:1 : not supported (xpost from vsphere hypervisor forum)
You can actually change the LUN# from the Clariion by finding the tab saying "Host LUNs" or something to that effect, but you don't really need to change the LUN#. The problem is that you probably had some other OS using the same FC card and the Clariion remembers it. The simple solution is to de-register the client. At least that's what worked for us.
Good luck,
Athanasios
