SRDF Operations Steps

As Gina  recommended, this has been moved to the Support Forums.

Thanks!

Some suggessition from my side for creating new srdf group

Create dynamic rdf group

Build dynamic SRDF pairs

Perform the initial SRDF full establish

Change RDF mode

symrdf addgrp -label new-group-name -sid 123 -rdfg 01 -dir 9d,8d -remote_sid 345 -remote_dir 9d,8d -remote_rdfg 01
symrdf createpair -file pair.txt -type r1 -sid 123 -rdfg 01 -invalidate r2 -nop
symrdf -g new-group-name establish -full
symrdf -g new-group-name set mode sync

But I need steps for

How we can add and delete device pair when we use dynamic rdf group with SRDF/S mode

How we add and delete device pair when we use dynamic rdf group with SRDF/A mode

The best option is download symmetrix procedure generator.

Can i know the download path for

symmetrix procedure generator.

Hello

Procedure generators can be located

Home --> Support --> Product & Diagnostic tools --> Procedure Generator

Thanks for the path. On that it has only how to add device pair to SRDF/A. How we can remove device pair from SRDF/A . Please let know the steps and command giude

Or simply type "procedure generator" in the search bar in the upper left

Is this steps is correct

Deleting Srdf/A Pair file
***********************
symrdf –g mySRDFAgroup disable -nop
symrdf -g mySRDFAgroup set mode acp_disk -nop
symrdf -rdfg 34 -sid 123 -file /var/tmp/pairfile.rdfg34 susp
symrdf -rdfg 34 -sid 123 -file /var/tmp/pairfile.rdfg34 deletepair -force
symrdf -g mySRDFAgroup  set mode async -nop

symrdf –g mySRDFAgroup enable –nop

Hi

This format looks good to go.......

Can we follow the same step for for adding and removing device to SRDF group if it cluster SRDF/A and SRDF/S allocation.

Hi All,

Sorry to pitch in so late,

How do is set up SRDF/A .Coule of steps i am aware however i am in confused in few steps

1)Create a device group and put the R1 device into that

2) make a file and put the device into that

3) do i need to establish the device in the createpair command only and then put into the Adaptive Copy mode and then set mode to Asyn.Can some one hlep me with the steps.

thanks

Ahmad Faraz

the below steps will do what u xplained aove

symrdf -v addgrp label testrdfg -rdfg xx -sid 1234  -dir 8c,9c -remote_rdfg xx -remote_sid 4321 -remote_dir 8d,9d

symrdf -sid 1234 createpair -f filename -type rdf1 -rdfg xx est -rdf_type acp_disk

symrdf -sid 1234 -f filename -rdfg xx set mode async

symdg import rdfggrpname -f filename

great .

i have read that we need to enable consistancy for SRDF/A...Does that follow the above mentioned steps or this is not necessary.

Suppose i need to add few more devices to the already exsiting SRDF/A replication device group .what are the steps that needs to be followed.

HI Ahmad,

If you wish to add deviced to an existing SRDF/A, you have two options:

1) either use the createpair command along with the ra group which is already in SRDFA

or

2) create a new ra group then do createpair and then use symrdf movepair command to move to an SRDF/A ra group.

things become little tricky when consistency is enabled for SRDF/A.

Saurabh
