Unless I'm misremembering, Deepak is normally working on IDS 7.13 (not
7.31). But, compared with OnLine 5.01, that's quite modern.

If the device names on the logical volume level are the same on both
machines, it shouldn't matter if the raw devices behind the logical volumes
are different.

With IDS 7.13, I don't think that is an option.

Upgrade to a version of IDS that support the features you want.
