Can i recover data once i dissocaite and remove a subdisk ?

Hello All,

Dear VxVM experts, i need clarity on a task i am going to perform.

Will i be able to recover data once i dissociate and remove a subdisk ? With the belw command for example:-

vxsd -g oradg -o rm dis oradg22-01

My task is to do a migration from one arrary to another using Veritas mirroring. I have done the mirroring part, so to remove the old disks i am planning to perform below steps.

1) vxplex -g oradg dis dumps-02                                    {Dissociate plex from the volume, Wait for some days and then proceed further}

2) vxsd -g oradg dis oradg37-01                                     {Dissociate subdisks from the plex}

3) vxedit -g oradg -r rm dumps-02                                  {Remove the dissociated plex from configuration}          

4) vxsd -g oradg -o rm dis oradg37-01                            {Remove the dissociated subdisks}

5) vxdg -g oradg rmdisk oradg37                                   {Remove the disks from existing DG}
 

Before i  remove the subdisk , i will wait for some days. Will i be able to revert to old disk after step 4 above if something goes wrong in the meantime.
