Except you can't do that if hdisk0 has active paging space on it.

I need to replace all four internal disks in my 7025-6F1. I have two
volume groups with two disks a piece. Both volume groups are mirrored.

My question is, are these disks hot-swappable? If so, all I would need
to do to replace a disk would be, say:

- unmirrorvg rootvg hdisk0
- reducevg rootvg hdisk0
- rmdev -l hdisk0 -d
- replace the disk with the new one
- cfgmgr
- extendvg -f rootvg hdisk0
- mirrorvg rootvg
- bosboot -a -d /dev/hdisk0
- bootlist -m normal hdisk0 hdisk1

Right?

The reason I ask is that I've just finished trying to do the exact same
thing with six 7044-270's and had atrocious luck with it. Just one
example: after having shut one of them down the system was unable to
boot and in the bootlist under SMS there wasn't a single harddisk to
chose from, even though I was expecting to see two.
