I received responses from the following individuals:
Carl Gaines cgaine_at_acxiom.com
Marco Luchini Marco.Luchini_at_acco-uk.co.uk
Roger Leonard rleonard_at_cvty.com
John Speno speno_at_isc.upenn.edu
Gary Hansford Gary.Hansford_at_gda.ge.com
Thank you all very much.
After reviewing everyone's ideas (five responses, five different approaches to the problem) I did the following:
1. removed the disklabel on rz13 (disklabel -z rz13).
2. relabeled the disk (disklabel -rw rz13 RZ13)
3. added to the LSM (voldiskadd rz13)
4. created the subdisk (volmake sd rz13-01 rz13,0,3556300)
5. created the plex (volmake plex vol-rz13-01 sd=rz13-01)
6. created the volume
(volmake vol vol-rz13 use_type=fsgen plex=vol-rz13-01)
7. started the volume (volume start vol-rz13)
8. created an ADVFS domain (mkfdmn /dev/vol/rootdg/vol-rz13 b2local)
9. created an ADVFS file set (mkfset b2local b2local)
10. created a directory (mkdir /b2local)
11. mounted the volume (mount b2local#b2local /b2local)
12. copied the data ( vdump -0 -f - /localb2 | (cd /b2local; vrestore -x -f -)
13. unmounted the old directory (umount /localb2)
14. removed the ADVFS domain and file set
(cd /etc/fdmns
rm -R /localb2)
15. removed the volume, plex and subdisk on rz45 with "dxlsm"
16. removed the label on rz45 (disklabel -z rz45)
17. created a new disklabel (disklabel -rw rz45 RZ45)
18. add the disk to LSM (voldiskadd rz45)
19. created a sub-disk (volmake sd rz45-01 rz45,0,3556300)
20. created a plex (volmake plex vol-rz45-01 sd=rz45-01)
21. attached the plex to the first volume to create the mirror
(volplex att rz13-01 vol-rz45-01)
22. waited approximately 2 hours as the volumes synced.
Piece of cake. (yeah, right)
