How to establish SRDF using VMAX All Flash?
Hi guys!
Need help regarding SRDF, I have an implementation using 2x VMAX 250F with SRDF/S via FC and eManagement in 2 different sites. Both VMAX are connected to MDS 9513 and connected to WAN via Nexus 7K. I have zoned the SRDF ports however the VMAXs cant detect each other. Is there anything I missed? Both VMAX 250F are using eManagement, is there any requirement for them to see each other using the embedded unisphere network (management network) just like using VNX Mirrorview or just FC connection?
Here are the zoning I did for your reference:
zoneset name VSAN800_Zoneset vsan 800
zone name SRDF_LOPEZ_1_DIR_1B_BAL_1_1B_PORT2 vsan 800
* fcid 0xc00000 [pwwn 50:00:09:75:a8:00:5c:06]
* fcid 0xdf0000 [pwwn 50:00:09:75:a8:00:60:06]
zone name SRDF_LOPEZ_1_DIR_2B_BAL_1_2B_PORT2 vsan 800
* fcid 0xc00020 [pwwn 50:00:09:75:a8:00:5c:46]
* fcid 0xdf0020 [pwwn 50:00:09:75:a8:00:60:46]
zone name SRDF_LOPEZ_1_DIR_1B_BAL_1_1B_PORT3 vsan 800
* fcid 0xc20000 [pwwn 50:00:09:75:a8:00:5c:07]
* fcid 0x4a0000 [pwwn 50:00:09:75:a8:00:60:07]
zone name SRDF_LOPEZ_1_DIR_2B_BAL_1_2B_PORT3 vsan 800
* fcid 0xc20020 [pwwn 50:00:09:75:a8:00:5c:47]
* fcid 0x4a0020 [pwwn 50:00:09:75:a8:00:60:47]
Hope to hear from you guys! Thanks in advance!

you need to create "relationship" if you will by creating an RDF group between these two VMAXs.
symrdf addgrp -label lopez -rdfg 9 -sid 00000001234 -dir 7h,8h -remote_rdfg 9 -remote_sid 0000005678 -remote_dir 10d,7d
so in this example i am adding rdf group "lopez", you can call it whatever you want, something that makes sense to you. Then i am specifying RDF group 9, nothing special about that number just needs to be a number that is not in use if this array is connected to another array via SRDF. Then you need to specify full serial number of source array (00000001234 in my example). Then you specify director name on source array. In my example director 7h on source array is zoned to director 10d on target array and source director 8h is zoned to director 7d on target array.

how do you determine that they can't see each other ? Did you try to create RDFG group ? If yes what was the syntax ?

Hi Dynamox
Thanks for your reply! Yes I tried the following commands after I zoned the two VMAXs
- symcfg discover
- symcfg list (I only see Local VMAX)
- symrdf -list -sid XXXX -ra all (I only see the RA ports from local VMAX)
- symrdf ping (it says no remote devices present)
I also tried to create a device group using Unisphere, when I scan for the remote VMAX, none appears.
Did I miss any steps?

Thanks Dynamox! It worked and I am able to detect both VMAX!
