I don't understand your question.  Sorry. 

The Celerra is wired to the SAN switch directly.  Here's one of the referenced FAs in the VSAN on the switch:

VSAN 101:

--------------------------------------------------------------------------

FCID        TYPE  PWWN                    (VENDOR)        FC4-TYPE:FEATURE

--------------------------------------------------------------------------

0x2b0001    N     50:06:01:61:41:e1:13:44 (Clariion)      scsi-fcp

                  [NS2_blade2_be1]

as you can see VCM is disabled, that means that any device that you map to that FA will be automatically visible to the host, in this case Celerra. No masking is available on those FAs.

Okay, I will leave it alone.  My problem is that I'm used to mapping storage and being able to see it from any server connected to the SAN.  But with this Celerra, I can only see the storage mapped to it from the Celerra itself, and using nas commands, not symcli commands.  How do I list storage presented to specific FAs then without knowing the WWN or device name?

Okay, I looked at another Celerra at a different site and it states "VCM_State" is Enabled:

[root@WWTP_Celerra bin]# ./symcfg list -fa 16C -p 0 -v -sid 78 | grep -i vcm

    Device Masking (VCM) Config State    : Mixed

    VCMdb Access Restricted State        : N/A

              VCM_State(VCM)               : Enabled

And this one has no problems listing devices.

If I enable the VCM_State, will it cause any connectivity issues with storage (or would I need to reboot the Celerra I made the changes on?)

it will have connectivity issues as you will need to mask all those devices to the FAs,  device names may get re-numbered. I have a feeling Celerra will not be very happy about that. What is the issue you are facing right now ? If you want to see what's presented to this Celerra and these FAs are dedicated to Celerra ..just look at devices mapped to those FAs.
