Replacing an LSM mirrored boot disk

Dear Managers,

I have a boot disk (rz17) who has a DETACHED STALE swapvol plex
(rz17b). This disk is mirrored via LSM to another disk (rz1).
I have tried to attach the plex, but LSM gives an error on a block of the
disk and i can't do this operation.

So, i must replace the original boot disk (rz17) with another good one
(rz1).

This is the configuration:

rz17a - rz1a --> rootvol
rz17b - rz1b --> swapvol (here is the problem)
rz17g - rz1g --> tmpvol

The root partition is using UFS and the /tmp file system is using AdvFS.

Can i do this steps:

a) Boot with rz1 disk
b) Remove from LSM all the stuff concerning to rz17 disk
c) Replace the rz17 bad disk with a new rz17 good one
d) Recreate the label on the new rz17
e) Mirror the rootvol and swapvol volumes with volrootmir
f) Mirror the tmpvol volume with volassist

Does it works ? Can i boot with the second disk (rz1) and create the
mirrors on the original boot disk (rz17) ? Is it necessary to rename the
volumes and plexes after this operation ?

Thanks in Advance
Best Regards
