Expanding Virtual Disks while Data Replication

I am using Continous Access replicating from an EVA8000 to EVA5000. If I expand an existing virtual disk on the EVA8000 with an active Data Replication stream, how will that affect the Data Replication, will it automatically expand the virtual disk on the destination (EVA5000)?
thanks,

Re: Expanding Virtual Disks while Data Replication

We use data replication, but between 5k and 5k. When you expand a vdisk on the source eva, the vdisk is expanded on the destination also.
Por que hacerlo dificil si es posible hacerlo facil? - Why do it the hard way, when you can do it the easy way?

Re: Expanding Virtual Disks while Data Replication

Gurdeep,

CA provides block level replication across EVAs. Whether you perform read/write I/Os to a Vdisk or modify the size of the Vdisk itself - it all points to block level modification. So, to my mind (haven't tried CA replication across 5K & 8K) this should be irrelevant. Change in size of the Vdisk should get reflected on the destination array just as change in data blocks on your source Vdisk gets reflected on the destination replica Vdisk.
