Can I restore a volume group from a system that has two hdisks to a system with only one?

I'm sorry, this question is related to a previous one, but the 'ask related question' feature does not function as advertised.

I have a volume group image that I created from a system on which that volume group was mirrored accross hdisk4 and hdisk5. I'm trying to clone it with restvg on a system on which only hdisk5 appears to be healthy. Can I do that? When I run restvg I'm getting an error that's rather vague, so I don't know whether it's the defective disk that's causing the problem. My assumption is that restvg restores the image to one of the disks, and that I would have to create the submirror afterwards.

Hi again,

unfortunately it's not possible to simply restore a mirrored VG to an unmirrorred one.

Is it an mksysb of the rootvg, or is it a savevg?

Is the originating system still functional so you could pull a new mksysb/savevg?

If so you could either unmirror the LVs in question or edit the /image.data resp.
/tmp/vgdata/[vgname]/[vgname].data file to only mention one copy and half the amount of PPs before writing to tape (see link below).

As it turns out, we decided to replace the defective drive which rendered the question, moot.
