I want to know we can change the device attr on the fly ?

Hi Experts,

I want to change the normal devices to the RDF capable but the device is having data in it . Is it possible whether i can go ahead and change the attributes on the fly or i have to take the downtime and then i have to change it

if i take the downtime for it . what happens to the existing data ??

Device is from VMAX VMAX20K and running with 5876 engunity code

The attributes dyn_rdf, dyn_rdf1, dyn_rdf2 can be assigned to a device after device creation.

Create a command file containing the following syntax:

          set device SymDevName attribute=device_attr;


Where SymDevName  is the name of the Symmetrix device being altered and  device_attr  is the attribute being assigned to the device.

Possible values for device_attr are:

  • dyn_rdf - Allows a device to be dynamically configured as an RDF1 or RDF2 device.
  • dyn_rdf1 - Allows a device to be dynamically configured as an RDF1 device only.
  • dyn_rdf2 - Allows a device to be dynamically configured as an RDF2 device only.

Unless this is on a VMax 10K. For the RDF attribute to be changed will require a BIN file update. With SRDF/DRDF enabled on a VMax 10K, all new devices get the attribute.
