Veritas InfoScale™ 7.4 Installation Guide - Solaris

To move volumes incrementally to disk partitions

1. Evacuate disks using the vxdiskadm command, the VOM GUI, or the vxevac utility.

   Evacuation moves subdisks from the specified disks to target disks. The evacuated disks provide the initial free disk space for volumes to be moved to disk partitions.

2. Remove the evacuated disks from VxVM control by entering:

   # vxdg rmdisk diskname 
   # vxdisk rm devname

3. Decide which volume to move first, and if the volume is mounted, unmount it.
4. If the volume is used as a raw partition for database applications, make sure that the application does not update the volume. Also make sure that you have applied the sync command to the data on the volume.
5. Create a partition on free disk space of the same size as the volume using the format command.

   If there is not enough free space for the partition, add a new disk to the system for the first volume removed. Subsequent volumes can use the free space that the removal of this first volume generates.

6. Copy the data on the volume onto the newly created disk partition using a command such as dd.

   # dd if=/dev/vx/dsk/diskgroup/lhome of=/dev/dsk/c2t2d2s7

   where c2t2d2 is the disk outside of Volume Manager and s7 is the newly created partition.

7. Replace the entry for that volume (if present) in /etc/vfstab with an entry for the newly created partition.
8. Mount the disk partition if the corresponding volume was previously mounted.
9. Stop and remove the volume from VxVM using the commands.

   # vxvol -g diskgroup stop volume_name
   # vxedit -rf -g diskgroup rm volume_name

10. Remove any free disks (those disks that have no subdisks defined on them) by removing the volumes from VxVM control.

    To check if there are still some subdisks remaining on a particular disk, use the vxprint command.

    # vxprint -g diskgroup -F '%sdnum' diskname

    If the output is not 0, there are still some subdisks on this disk that you need to remove. If the output is 0, remove the disk from VxVM control.

    # vxdg rmdisk diskname 
    # vxdisk rm devname

    Use the free space that is created for adding the data from the next volume you want to remove.

11. After you successfully convert all volumes into disk partitions, restart the system.
12. After the restart, make sure that none of the volumes are open by using the vxprint command.

    # vxprint -Aht -e v_open

13. If any volumes remain open, repeat the steps.
