SRDF/S - Getting errors trying to create dynamic RDF group

                S Y M M E T R I X   R D F   G R O U P S             

    Local              Remote                   Group               RDFA Info
--------------  ---------------------  -----------------------  -----------------
            LL                                      Flags  Dir  Flags  Cycle

  1 ( 0)    10    1 ( 0) xxxxxxxxxxxx  S GROUP_00    .X..  F-H  -IS-      30   33

Attempting to run this command to create a new dynamic RDF group:

symrdf addgrp -label Group_02 -fibre -sid xxxx -rdfg 2 -dir 04d -remote_sid xxxx -remote_dir 04d -remote_rdfg 2

I receive this error message:

'2': duplicate name found in device list.

I've tried using many other numbers for the rdfg parameter, but always got the same result. Anyone experience this and know resolution?

Thanks.

yep ..looks like you are missing stuff, here is from a working DMX4

symcfg list -v -sid 1234 | grep -i rdf

Switched RDF Configuration State     : Enabled
    Concurrent RDF Configuration State   : Enabled
    Dynamic RDF Configuration State      : Enabled
    Concurrent Dynamic RDF Configuration : Enabled

Tried:

symrdf addgrp -label Group_02 -fibre -sid xxxx -rdfg 2 -dir 04d -remote_sid 000xxxxxxxxx -remote_dir 04d -remote_rdfg 2

Got:

'2': duplicate name found in device list.

Also ran this to ensure I wasn't crazy...

symcfg -sid xxxx list -rdfg 2

Result:

The specified RA group is not valid

try adding the full serial number of the remote array including the 3 leading 0's for the SID.

symrdf addgrp -label groupname -rdfg # -sid XXXX -dir YY -remote_rdfg # -remote_sid 000XXXXXXXXX -remote_dir YY

I think maybe the issue is the group name (-label Group_02).

Can you verify there is not another Group_02 on either the Source or Target arrays.

This could also be a static group defined when the bin file was built.

There is only group 1 on both, and it is static.

can you run "symcfg discover" and then "symcfg list -sid XYZ -RA ALL" just to double check it's really not there.

Hello,

  Is there any more info in the symapi log file?

If your current SRDF is static is the dynamic rdf flag enabled in the bin file?

I tried it from the other side and this is the output:

symcfg list -sid xxxx -ra all

Symmetrix ID: 000xxxxxxxxx

                 S Y M M E T R I X    R D F    D I R E C T O R S

                                         Remote        Local    Remote

RF-13D  13D   61    13  RDF-BI-DIR   -   000yyyyyyyyy   1 (00)   1 (00) Online

When I attempt to create the rdf group from the other site, I get the message:

The feature being requested is not currently licensed

Am I missing something? Here is an excerpt from the symapi_licenses.dat file:

Also, there appear to be no DG or CG on this system, which doesn't make sense to me..but then again, I'm no RDF expert.

symdg -sid xxxx list

No Symmetrix CGs were found

unless you are using GNS devices groups are local to that particular host.

Is there a symcli command to determine for sure whether dyn_rdf is enabled on an array?

Never mind my last question, guys. I was apparently having a Monday moment!

Dynamic RDF Configuration is enabled on the array.

i guess we never asked the question, are these RAs zoned to each other or you have direct connectivity from RA to RA ?

OK, I've tried again from the original site, and now I'm getting this message:

The switched or dynamic RDF features are not properly enabled in the symmetrix, or the symmetrix are connected point to point

This is from the symapi log file:
