To remove Veritas Storage Foundation, complete the following preparations before the uninstallation:

• Back up all VxFS file systems in full and move the files in all VxFS file systems to native file systems backed with LVM logical volumes. Raw application data stored in VxVM logical volumes must be moved to LVM logical volumes.

• Remove all but one copy of file systems and databases.

• Remove all but one plex from volumes that contain multiple plexes (mirrors). To display a list of all volumes, use the command:

  # vxprint -Ath

  To remove a plex, use the command:

  # vxplex -g diskgroup -o rm dis plex

• If a remaining plex contains multiple subdisks, consolidate the subdisks into a single subdisk using the commands:

  # vxassist -g diskgroup mirror volume layout=contig
    # vxplex -g diskgroup -o rm dis plex

  Sufficient space on another disk is required for this operation to complete.

• Modify /etc/filesystems to remove or change entries for VxFS file systems that were moved to native file systems.

• Move all data from volumes created from multiple regions of storage, including striped or spanned volumes, onto a single disk or appropriate LVM logical volume. This can be done using one of the following three methods:

  • Back up the system to tape or other media and recover the system from this.

  • Move volumes incrementally (evacuate) onto logical volumes. Evacuation moves subdisks from the source disks to target disks. The evacuated disks provide the initial free disk space for volumes to be moved to LVM volumes.
