If you have HP EVA array, the answer is YES. Which model of HP EVA do you have?

Do you want to add a physical disk or a vdisk?

Vdisk

You can do this at any time. Just use CV to create the vdisk, select size and RAID level.

Adding vdisk is an online operation and can be done during bussiness hours.

What about present new Vdisk to servers which they have replication 2 Vdisks ? Is there any exceptions of adding Vdisk in business hours !

VDisks can be presented and many operating systems can even pick up the new disks without a reboot.

Creating a new Data Replication Group with a new VDisk or adding a VDisk to an existing DRG can be done online, too.
Just be careful that on a recent system, a new DRG will implicitly create a 100GB write history log (WHL) - that is an internal VRAID-1 VDisk, so it will use 200GB of raw space.
