This is for SRDF/S. SRDF/A is some more complex.

Hi,
Following are some typical steps for SRDF/S operations. I hope it will helpful to you.
To get the details, please refer "SRDF Control Operations Guide" attached. Its an excellent handbook.
Display info. about R1 and R2 devices
# symrdf list
# symdev list R1
# symdev list R2
Create device group & add devices into it
# symdg create -type
# symld -g -sid XXXX add dev
# symdg show show
Querying & listing device group & devices
# symrdf -g query
# symcfg list
# symdev show
# symcfg list -ra all ( displays RLD info. by reaching symm units one or two hops away)
SPLIT
# symrdf -g -noprompt split
ESTABLISH
# symrdf -g -noprompt establish
RESTORE
# symrdf -g -noprompt restore
FAILOVER
# symrdf -g -noprompt failover

Wow Sanjay that paper is really, really old! I haven't been deep into SAN myself for about 3 years now (started working more on the network management side), but I would imagine that some of those commands may be outdated. (SAN guys help me out?).
Your best bet is always to go to Powerlink for the most up-to-date documentation.
Just a reminder to everyone - as long as these technical questions aren't talking about production environments, its ok to have them here. If the threads start getting to specific to actual environments, its really better to have the conversation over in the EMC Support Forums.
Also, I'm moving this thread up to the main Proven Professional community. The Advisor section is really more for getting advice on the certification exams, courses to take, etc.
Thanks!

Yeah.. may be some of the commands are out dated... still most are working fine ... I am using them in my work.
However, the recent document is available @ Home > Support > Technical Documentation and Advisories > Software ~ S ~ Documentation > Solutions Enabler > v7.1.x

Once we create a Device Group, Add devices to device group, Set Mode on the local & remote machine. How does the system know that it has to transfer data to a particular devices in the Device Groups.?
Do we have to specify any relationship b/w R1(newsrcdg) & R2(newtgtdg) device group?
Regards

Hello Bharath,
The pairing relationship is defined at the device file level.
The device file (-file) option directs the specified operation in the symrdf
command to a device file.
The device file contains device pairs (SymDevnames) listing
a pair for each line.
Device files can include comment lines that begin with the pound
sign (#).
The following example illustrates the file format, which specifies three
device pairs:
00A1 0103
00A2 0104
#00A3 0105 (To be reinstalled later)
00B1 0106
Any suggestion/comment is much appreciated.
Thank you
Sanjit Achary

But it looks like in your earlier posting of SRDF steps you haven't introduced any command with the file option. Please correct me if i'm wrong.
Thank You

Hi guys -
I'm going to move this over to the Support Forums as well. It is great how everyone is contributing, thanks so much!
One thing to be aware of: you need a very thorough understanding of what these commands do, and what the unintended consequences of running a certain command with a certain flag will be on your storage environment. It is possible to use these commands incorrectly, and the results of that could be very, very bad.
Managing a storage array is something you really must have formal training on, especially when you are first starting out!
So, I'm going to move this over to the support forums where our services folks can help you all keep this converstation going!

Thanks Alexey Yakovenko,
Now I got an idea how to pairup devices, create Dynamic Groups and perform Dynamic SRDF operations.
Once again thanks to EMC Community. If anybody could be more explain more by taking an example that would be great.
Thank You
Bharath
