Moving data from "oldarray" to "newarray"
1. Connect the newarray to the Sun server.
2. Verify that Solaris and VERITAS can see the disks in newarray. You can use 'vxdisk list' to see the disks in VERITAS, they should be listed in "error" at this time. (Figure 1)

c1t6d0s2 sliced disk03 testdg online
c2t3d0s2 sliced - - error
c2t4d0s2 sliced - - error
c2t5d0s2 sliced - - error
3. Determine amount of disk space needed for each disk group using 'vxprint -ht' (Figure 2)

The test output shows that each volume is 100 mg. So a total of 300 mg of disk space is needed from the new array.
3.1 Do vxdisksetup for disks which you need to get under VXVM control from new disk array.
# vxdisksetup -i
4. Add the necessary amount of disks from the newarray to each disk group as determined by step 3
vxdg -g adddisk =
Repeat this step until all the disks are added to the disk group.
vxdg -g testdg adddisk disk04=c2t3d0
vxdg -g testdg adddisk disk05=c2t4d0
5. Mirror the oldarray plexes against the newarray disks so there is now a plex made up of disks from the newarray (Figure 3)
vxassist -g mirror alloc=,
vxassist -g testdg mirror vol01 alloc=disk04
vxassist -g testdg mirror vol02 alloc=disk04
vxassist -g testdg mirror vol03 alloc=disk04,disk05

oldarray plexes

7. Verify you broke off the plexes that contain the
oldarray disks by using
vxprint -ht. If you are not satisfied with the new array, you will be able to reattach the plex.
8. When you are confident that the new array is stable, remove the disassociated plexes.

9. Then remove the disks from the old array so that the old array can be disconnected
vxdg -g rmdisk
vxdg -g testdg rmdisk disk01
vxdg -g testdg rmdisk disk02
vxdg -g testdg rmdisk disk03
10. Power the server off to remove the old array.
11. Boot it back up with a reconfigure reboot to clean up the device tree.
12. Finally, as an option, clean up the vxprint by renaming each of the plexes, disks and subdisks so it looks like your original vxprint
Rename the plex:
vxedit -g testdg rename vol01-02 vol01-01
vxedit -g testdg rename vol02-02 vol02-01
vxedit -g testdg rename vol03-02 vol03-01
Rename the disk:
vxedit -g testdg rename disk04 disk01
vxedit -g testdg rename disk05 disk02
Rename the subdisks:
vxedit -g testdg rename disk04-01 disk01-01
vxedit -g testdg rename disk04-02 disk01-02
vxedit -g testdg rename disk04-03 disk01-03
vxedit -g testdg rename disk05-01 disk02-01
13. Then you can do a vxprint -ht to compare it to your first vxprint. The only difference should be the c#t#d# in sd column 8 that are now on the new array. (Figure 6)
