Go to SolutionCreating DRV(Dynamic Relocation Volumes)
Hi,
We are about to set up optimizer and I was just wondering on how to create DRV's that are required to perform swaps.
Any information on how to create (symcli command) would be useful. What are the best practices for creating DRVs.
Thanks in Advance

Reply Optimizer works best when all your devices are the same size.
The DRVs should be as large as your largest device that will be optimized.
You need 2 DRVs for each swap that you want to be executed concurrently. I think there is a difference in protection on VMAX vs. DMX. Is your case a DMX or a VMAX?

DRV's are unprotected devices what array model are you trying to do this on and what code is it running (enginuity)?
You would have to create an unprotected device and then set the DRV flag on it.
And you may want to check this thread or I could just poach all of Stefano's data that he posted here.
Reply Thanks Quincy!...at this time we are trying to set optmz on VMAX running 5875, the SE is 7.2.1.
I still wanted to know how to create a DRV. is there a command. symconfigure does not have one with the DRV attribute.
Also should the DRVs be created on a per diskgroup basis?Since you said 2 or more, where should these be created.
Reply With SMC if you select "Create Device" then in the Regular Device tab the option "Configuration" should have DRV as an option.
As mentioned for a VMAX the DRV are protected but I would assume this would be taken care of by SMC.
The disk group is not important for the DRV volumes however it may be of concern to your system layout or perfomance requirements.
Steve.

Stefano Del Corno did all sorts of work with this in the thread I posted a link to.

Hi,
With Enginuity 5874, only mirrored DRV devices can be created.So, you would need to use the syntax:
create dev count=X, size=XXXXXX cyl, emulation=XXX, config=2-Way-DRV-Mir
