Another thing I could suggest would be that LV mirrors will need to be respected too. I fell over that when restoring to a server with a HUGE single disk protected externally. I can't remember if it was local hardware RAID or a SAN.
The problem is that the mirrors have to go on separate PVs (as far as the OS knows) and we just had one. There was an unsupported adjustment that I had to do to the volume group definition file (created by mkszfile) before running mksysb but once it's written you are a bit stuck.
I have seen it done by DR provider professionals where they copy the image into a NIM server and adjust it, but that's just me witnessing it rather that knowing what they did.
Is your DR site and equipment owned by your company or is it rented time from a DR specialist company?
I must say that using tapes for such a large rootvg seems a little odd. Is there not a DVD-RAM drive available?
Kind regards,
Robin

Hello Guys,
Can before and after snapshots be used to verify successful filesystem restoration?
snapshots will be created using fssnaps and restoration is thru legato restore?
Any ideas on this? or any other ways I could verify that restoration is good?
