From above output:

- Mig31Data is mirrored on sdj, sdl

- Mig31Jrnl is mirrored on sdm, sdp

Assuming you want to convert the volumes to concat (and still use the same disks), the following would work (assuming these volumes are the only volumes on these disk(s) - if that this not the case, provide vxprint output before proceeding):

1. remove the mirror plex from both volumes:

# vxplex -g <diskgroup> -o rm dis Mig31Data-02

# vxplex -g <diskgroup> -o rm dis Mig31Jrnl-02

2. Grow the volumes onto the freed up disks - ensure the dmname is included in the specification to grow onto the correct disk(s):

# vxresize -F <fstype> -g <diskgroup> Mig31Data +230686720 disk04

# vxresize -F <fstype> -g <diskgroup> Mig31Jrnl +230686720 disk01

3. Check

# vxprint -qhtrg <diskgroup> Mig31Data Mig31Jrnl

MIG31,

The output of vxprint confirmed it's good to go with proceeding the actions g_lee given.

Good Luck !
