Set Dynamic SRDF between DMX 3000 and DMX 4 for A lun

Hi

Let me explain my situation:

I have two DMX boxes one of them is a DMX 3000 and the Second one a DMX 4, i need to replicate one Lun from the DMX 3000 to DMX 4, the Lun on the DMX 3000 is a meta head with  16 members and its configuracion is as follows

    Device Configuration     : RAID-S (7+1)    (Meta Head,

--> 1009   8714        -       -  N/A                -      - N/A           
        100A   8714        -       -  N/A                -      - N/A           
        100C   8714        -       -  N/A                -      - N/A           
        100B   8714        -       -  N/A                -      - N/A           
        100D   8714        -       -  N/A                -      - N/A           
        100E   8714        -       -  N/A                -      - N/A           
        100F   8714        -       -  N/A                -      - N/A           
        1010   8714        -       -  N/A                -      - N/A           
        1011   8714        -       -  N/A                -      - N/A           
        1012   8714        -       -  N/A                -      - N/A           
        1013   8714        -       -  N/A                -      - N/A           
        1014   8714        -       -  N/A                -      - N/A           
        1015   8714        -       -  N/A                -      - N/A           
        1016   8714        -       -  N/A                -      - N/A           
        1017   8714        -       -  N/A                -      - N/A           
        1018   8714        -       -  N/A                -      - N/A

And the target lun on the DMX 4 is:

03C5 es a Meta Head with 16 Members

i want to replicate the Lun 1009 to 03C5, dont worry about the conections I have all conections and the Link is ready between boxes.

The problem Here is:

The lun 1009 is a production Lun, do i need to set the RDF1 to the Lun? wont it  afect it? the third thing is if you see the members the sequence is wrong

1009   8714        -       -  N/A                -      - N/A           
        100A   8714        -       -  N/A                -      - N/A           
        100C   8714        -       -  N/A                -      - N/A           
        100B   8714        -       -  N/A                -      - N/A           
        100D   8714        -       -  N/A                -      - N/A

if you see there are luns like 100A  and the next is 100C and so on.

I dont know how the customer created this meta by using no sequential meta members.

Please could you tell me how can i replicate this lun from the box DMX 3000 to DMX 4 by using Solutions Enabler to a Sequential Lun on the DMX 4 Box

Please tell me the steps.

Best regards

Hello Guanabocoa,

     What are the enginuity families bewteen the two DMX's?

Hi

Please can you check my script so that o can configure Dynamic SRDF.

Both Symmetrix are not Dynamic RDF capable i need to set the Flag         
DymRDF548.txt         
set Symmetrix dynamic_rdf=enable;         
symconfigure -sid 548 -f DymRDF548.txt preview -v         
symconfigure -sid 548 -f DymRDF548.txt prepare -v         
symconfigure -sid 548 -f DymRDF548.txt commit -v         
DymRDF540.txt          
set Symmetrix dynamic_rdf=enable;         
symconfigure -sid 540 -f DymRDF540.txt preview -v         
symconfigure -sid 540 -f DymRDF540.txt prepare -v         
symconfigure -sid 540 -f DymRDF540.txt commit -v         
*************************************************         
I need to create the Dynamic RDF Group         
symrdf addgrp -label dyngrp4 -rdfg 4 -sid 548 -dir 08d -remote_rdfg 4 -remote_sid 540 -remote_dir 8d         

Question: I have 2 RA ports how can i add the 09D?         
Question: this command creates the RDFG 4 in both boxes or i need to create the RDFG 4 in the remote box?         
Question: Can i use the same RA ports? Wont it affect my current static replication?         
*************************************************         
set source device to be R1          
set device 1009 attribute=dyn_rdf1_only;         
set device on DMX4 to R2         
set device 03C5 attribute=dyn_rdf2_only;         
*************************************************         
Create a file that contains source in one column and target in another         
Lunfile_1009.txt         
1009    03C5         
*************************************************         
Check the RDF groups         
symcfg -RA all list         
symcfg -sid 548 list -rdfg all         
Create the pair between boxes         
symrdf createpair -file Lunfile_1009.txt -sid 548 -rdfg 4 -type rdf1  -invalidate  r2               
This step initiats the actual copy         
symrdf –f Lunfile_1009.txt establish -sid 548 -rdfg 4         
symrdf -f Lunfile_1009.txt set mode acp_disk -sid 548 -rdfg 4         
Note:         
548 local         
540 remote

Thanks

Hi Guanabacoa,

Question: I have 2 RA ports how can i add the 09D?

Saurabh : You can add another RF port to your RA group using symrdf modifygrp command:

symrdf modifygrp <-add | -remove>
      <-rdfg | -label >
      -sid [-dir

] [-remote_dir ]
      [-noprompt] [-i ] [-c ] [-star]

Question: this command creates the RDFG 4 in both boxes or i need to create the RDFG 4 in the remote box?

Saurabh: Yes in both Symm. No need to create RDFG in remote Symm.

Question: Can i use the same RA ports? Wont it affect my current static replication?

Saurabh: RDF works on logical link (RDFG links), It can use the same port for static as well as for dynamic.

Rest all looks fine to me..if anyone wants to add or advise please do so..

Thanks,

Saurabh

I need to create the Dynamic RDF Group         
symrdf addgrp -label dyngrp4 -rdfg 4 -sid 548 -dir 08d -remote_rdfg 4 -remote_sid 540 -remote_dir 8d         

Question: I have 2 RA ports how can i add the 09D?         
Question: this command creates the RDFG 4 in both boxes or i need to create the RDFG 4 in the remote box?         

1)  symrdf addgrp -label dyngrp4 -rdfg 4 -sid 548 -dir 08d,09d -remote_rdfg 4 -remote_sid 540 -remote_dir 8d,09d

2) rdfg 4 will be created on both boxes.

Guanabacoa,

you srdf mode is acp_disk, what mode are you planing, sync or async. if so you need to set the mode, once both are in sync.

Hi

I used these commands to set both boxes Dynamic RDF capable and it worked fine

DymRDF548.txt  
set Symmetrix dynamic_rdf=enable;  
 
DymRDF540.txt   
set Symmetrix dynamic_rdf=enable;  

But when i tried to create the new Dynamic RDF group by using this command:

symrdf addgrp -label dyngrp4 -rdfg 4 -sid 548 -dir 08d,09d -remote_rdfg 4 -remote_sid 540 -remote_dir 8d,09d

But i got these error message:

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

But the Dynamic RDF capable flag is already enable in both boxes.

how can i resolve this?

do i need to configure something else?

Do i need to set the properties to switched?

how can i do that?

if you have any workaround can i perform it on the fly without affect my current static replication, i mean, no split, no suspend, etc?

Best regards

is switched enabled on both arrays ?

hi

switched is not enable en both boxes, let me tell you i have point to point connection, i mean, DMX 3000 8d 9d to DMX 8d 9d back to back.

What happens if i enable switched en both boxes (how can i do that?) will it affect my current static replication(configuration) do i need to split my current static replication to do that? o can i do that on the fly?

Best Regards

HI,

You need to have a switch between these two Symm to configure Dynamic SRDF. Point to Point connetion is only for Static SRDF.

Thanks,

Saurabh
