To preserve the existing configuration information, perform the following actions:

• Make a record of the mount points for VxFS file systems and VxVM volumes that are defined in the /etc/fstab file. You will need to recreate these entries in the /etc/fstab file on the freshly installed system.

• Before upgrading, ensure that you have made backups of all data that you want to preserve. In particular, you will need the information in files such as /etc/fstab. You should also run the vxlicrep, vxdisk list, and vxprint -ht commands, and record the output from these. You may need this information to reconfigure your system after the upgrade.

• Use the vxlicrep command to make a record of the currently installed Veritas licenses.

• Back up the configuration files.

  #cp -r /etc/VRTSvcs/conf/ backupdirectory/

• If Veritas Volume Replicator (VVR) is configured, do the following steps in the order shown:

  • Make sure that the disk groups that contain RVGs are at least at disk group version 110.

    # vxdg list diskgroup

  • Make sure the size of the SRL volume is greater than 110 MB.

    Refer to the Veritas Volume Replicator Administrator's Guide.

  • Stop all the applications involved in replication. For example, if a data volume contains a file system, unmount it.

  • Verify that all of the Primary RLINKs are up to date:

    # vxrlink -g diskgroup status rlink_name

  Note:

  Do not continue until the Primary RLINKs are up to date.
