We are planning to implement cross site lvm mirroring.Can i configure the machines in the DC site in the standalone mode and later do cross site mirroring once the DR site is ready.

If your mirroring using the lvm on logical volumes there is no reason why you cannot add the lv copies at a later date and maybe mirror locally as an interim solution. Synchronising the mirrors can be done on-line although it can be very cpu intensive and you may want to do this offline
