How to find a device belongs to which srdf group ?

should see this on the symdev -sid xxx show for the device.

or

symrdf -sid xxx list | grep

both outputs should get you what you need.

Ok thanks for reply and is there any command to find the SRDF GROUP NAME which v add these devices?

SRDF_xxxx - DG name

On the symdev show

RDF Information

        {

        Device Symmetrix Name                  : 0895

        RDF Type                               : R1

        RDF (RA) Group Number                  :  64 (3F) <<

No no, i want the command to find the device belongs to SRDF GROUP NAME?

For example,

Normally v r adding the symld -sid xxxx -g groupname add dev xxxx rite ?

like this symrdf -g groupname query so this case how to find that device belongs to the particular group ?

here you can see symrdf -sid xxx list on my machine,  showing dev 0895 is in RDFG 64.

symrdfg list -rdfg all -sid xxx will give you the names on there for the RDFG.

If it's the device group then this is on the symdev show output also.

Hi Anil,

Your answer will go like this, to find all information regarding SRDF groups, and which devices belong to a specific RDF group you have to write as follows:

symcfg list -sid xxx -rdfg all

In my confiuration, we have two vmax, one local an the other remote, we use the same RDF group name in both, and we have one containing all R1 and R2 devices in it, son when you query the command explained above, don't expect to find many groups.

I hope this information helps you, do not hesitate to ask if you need further explanation.

Regards

try a symdev show -sid |find "Device Group"

try symdev -sid show | find /I"Device group"

Note: Device should be a local dev to that particular array.

Just run the command from the host(for which this device is local):

$ symdev show |more

Symmetrix ID: 000xxxxxxxx (symmetrix-id)

Device Physical Name    : Not Visible

Device Symmetrix Name    : 3273

Device Serial ID        : N/A

Symmetrix ID            : 000xxxxxxxx(symmetrix-id)

Device Group Name        : dg_opt_oradata <<--  This is the DG name you are looking for.

Device Logical Name      : DEV016

...

....

(output truncated)

The following snippet will work all this out and create corresponding files with the list of devices in each, I’m sure there’s a few more ways you can do it, this was the first and easiest that came to mind. Be sure to change the sid

for i in `symcfg -sid 002 list -rdfg all | grep 000 | awk '{print $1}' | grep -v Symmetrix`; do symdev -sid 002 list -rdfg $i -nomember >>symm002RDFG$i.txt; done
