SRDF initial setup

what type of connection between two arrays, IP or fabric extension ? You need to establish communication between RA ports, if FC connectivity you will need to zone RA ports from two arrays and then create RDF group(s).

Hi Dynamic,

Thank you for your response.

These two arrays are located in different cities and I am assuming that they are connected through IP.

Does your array have Gige RA ports ?

Hi Dynamox,

I still did not visited the Data Centre, I am sure there will be GigE RA

ports.

If possible, could you please provide me the steps which I need to follow

at the array end after the physical connectivity.

It would be great if you can assist me in this case.

Thank you in advance.

I don't have experience with GigE so can't help you there. Once you establish connectivity you will need to create an RDF group between the array. To see already used/available RA groups you would run this command:

symcfg list -sid 1234 -RA ALL -switched

then you create the actual group

symrdf addgrp -label 234to789 -rdfg 9 -sid 000000001234 -dir 7h -remote_rdfg 9 -remote_sid 00000006789 -remote_dir 10h

again this is what i do when i connect two arrays via FC, i am not sure if these commands are different for when you configure connectivity via GigE.

You can contact your local account team to get access to Unisphere for VMAX access from the Service Processor as another management alternative.

Hi!

You can check by this command:

symcfg -sid 1234 list -dir ALL

if you will not see in Type column something like RDF, then you should ask you local EMC staff to make some ports on director as RDF ports. I'm not sure but seems for me only EMC staff can do that by SymmWin.

If you have RFD ports, then you need to zone them to each other R1 site <-> R2 site (dynamox mentioned about that)

as soon as you zone it you can check the connectivity by

symrdf ping

your remote box should answer like that:

Successfully pinged (Remotely) Symmetrix ID: XXXXXXXXXX

it doesn't not matter for your which interface you use Gigi or FA, of course need to have different settings (like Jumbo frame on gigi, or proper BB credit on SAN switch for FC, it depends from a environment)

For new RDF group you can use command from dynamox.

Thanks!
