Moving Volumes from a VM Disk

Before you disable or remove a disk, you can move the data from that disk to other disks on the system. To do this, ensure that the target disks have sufficient space, and then use the following procedure:

1. Select menu item 6 (Move volumes from a disk) from the vxdiskadm main menu.
2. At the following prompt, enter the disk name of the disk whose volumes you wish to move, as follows:
     Move volumes from a disk 
     Menu: VolumeManager/Disk/Evacuate 
   Use this menu operation to move any volumes that are using a
   disk onto other disks. Use this menu immediately prior to
   removing a disk, either permanently or for replacement. You can
   specify a list of disks to move volumes onto, or you can move the
   volumes to any available disk space in the same disk group.
   
     NOTE: Simply moving volumes off of a disk, without also removing
        the disk, does not prevent volumes from being moved onto
        the disk by future operations. For example, using two
        consecutive move operations may move volumes from the 
        second disk to the first. 
   
     Enter disk name [<disk>,list,q,?] mydg01 
   

   You can now optionally specify a list of disks to which the volume(s) should be moved:

   
     VxVM INFO V-5-2-516 You can now specify a list of disks to move
     onto.  Specify a list of disk media names (e.g., mydg01) all on
     one line separated by blanks. If you do not enter any disk media
     names, then the volumes will be moved to any available space in
     the disk group.

   At the prompt, press Return to move the volumes onto available space in the disk group, or specify the disks in the disk group that should be used:

   
   Enter disks [<disk ...>,list] 
     VxVM  NOTICE V-5-2-283 Requested operation is to move all
     volumes from disk mydg01 in group mydg.
   
     NOTE: This operation can take a long time to complete. 
   
     Continue with operation? [y,n,q,?] (default: y)

   As the volumes are moved from the disk, the vxdiskadm program displays the status of the operation:

   
     VxVM vxevac INFO V-5-2-24   Move volume voltest ...

   When the volumes have all been moved, the vxdiskadm program displays the following success message:

   
      VxVM  INFO V-5-2-188 Evacuation of disk mydg02 is complete.
3. At the following prompt, indicate whether you want to move volumes from another disk (y) or return to the vxdiskadm main menu (n):
     Move volumes from another disk? [y,n,q,?] (default: n)
