              Your bill of materials and indented bills report specify
              the contents of your media. Be sure to verify the contents
              of your kit with this information. If your kit is damaged
              or if parts are missing, contact your HP representative.

              The installation procedure for the Disk File Optimizer
              provides online release notes. HP strongly recommends
              that you read the release notes before proceeding with
              the installation. For information on accessing the online
              release notes, see Table 1-6.

              The Disk File Optimizer software installation procedure
              converts existing scheduling database files to the new
              version. If you have Disk File Optimizer V1.1 to V2.0,
              the installation will convert your Rdb database to an RMS
              database. If you are installing Disk File Optimizer Version
              1.0, see Section 1.2.1 before installing.

                1.2 Preparing to Install the Disk File Optimizer Software


        1.2.1 Upgrading From Disk File Optimizer V1.0

              If you are upgrading from Disk File Optimizer V1.0 and want
              to save the data in your database, you must save the data
              in a command procedure. Perform the following command to
              save in a command procedure:

              $ DEFRAGMENT SHOW */COMMAND/OUT=LOAD_DB.COM

              This command saves the data from your Rdb database and
              allows you restore it after installation of Disk File
              Optimizer.

        1.2.2 Installation Variants

              The Disk File Optimizer kit allows for two installation
              variants:

              o  Defrag, which provides capabilities to defragment files
                 and volumes

              o  Defrag PLUS, which provides all the capabilities of
                 Defrag plus scheduling and command storage options

              Table 1-1 identifies the major differences between Defrag
              and Defrag PLUS.

              Defrag is recommended on any system where the additional
              features are not desired or where disk space is very
              limited.

              Defrag PLUS is recommended on VMScluster systems and on any
              single-node system where the additional features of Defrag
              PLUS are desired.

        1.2.5 Process Account Quotas

              The account you use to install the Disk File Optimizer
              software must have sufficient quotas to enable you to
              perform the installation. Table 1-4 summarizes the process
              quotas required for the installing account, regardless of
              which installation variant you install.

              User account quotas are stored in the SYSUAF.DAT file.
              Use the VMS Authorize utility (AUTHORIZE) to verify and
              change user account quotas. First set your directory to
              SYS$SYSTEM, and then run AUTHORIZE:

              $  SET DEFAULT SYS$SYSTEM
              $  RUN AUTHORIZE
              UAF>

              At the UAF> prompt, enter the SHOW command with an account
              name to check a particular account, for example:

              UAF>  SHOW SMITH

              To change a quota, enter the MODIFY command. The following
              example changes the FILLM quota for the SMITH account, and
              then exits from the utility:

              UAF>   MODIFY SMITH /FILLM=50
              UAF>   EXIT

              After you exit from the utility, the system displays
              messages indicating whether or not changes were made. Once
              the changes have been made, you must log out and log in for
              the new quotas to take effect.

              For more information on modifying account quotas, see the
              description of the Authorize utility in the OpenVMS System
              Management Utilities Reference Manual.

        1.2.6 VMScluster System Considerations

              Use the following list of guidelines when installing the
              Disk File Optimizer on a VMScluster system:

              o  For Defrag PLUS, the scheduling database should be
                 accessible from all nodes in the cluster.

                 Make sure to place the scheduling database on a cluster-
                 accessible disk. Defragmentation can occur only from
                 nodes that can access the database.

              o  For Defrag PLUS, defragmentation can occur only on those
                 nodes running a scheduler process.

                 The scheduler creates defragmentation processes and
                 runs them as detached processes. Because of this,
                 defragmentation can occur only from nodes that have a
                 running scheduler.

              o  After installation, install the latest version of
                 DCLTABLES.EXE on all nodes of your system.

                 To make the Disk File Optimizer available on all nodes
                 of the cluster, you should ensure that all nodes have
                 the latest version of DCLTABLES.EXE installed. Use
                 SYSMAN or log in to each node in the cluster and enter
                 the following command:

                 $ INSTALL REPLACE SYS$COMMON:[SYSLIB]DCLTABLES.EXE

              o  Be sure to install Disk File Optimizer on both the VAX
                 and Alpha system in your VMScluster if it is a mix of
                 VAX and Alpha systems.

              o  During installation of DFO on a cluster with multiple
                 system disks, you must shut down the scheduler before
                 starting the installation on the next node. Use the
                 following command:

                 $ @SYS$MANAGER:DFG$STOP_SCHEDULER

                1.2 Preparing to Install the Disk File Optimizer Software


                 During the Installation Verification Procedure (IVP) the
                 scheduler is started on the node that the installation
                 was just completed on. After completion of installation
                 on all nodes, restart the scheduler on all licensed
                 nodes in the cluster. Use the following command:

                 $ @SYS$STARTUP:DFG$STARTUP

        1.2.7 Definition of SCSNODE or SYS$NODE Considerations

              Defrag PLUS requires either SCSNODE (SYSGEN parameter)
              or SYS$NODE (DECnet logical) be defined on the node that
              Disk File Optimizer is installed on. If both SCSNODE and
              SYS$NODE are NOT defined, the Disk File Optimizer scheduler
              will not start.

              If the node is part of a cluster then SCSNODE has to be
              defined in SYSGEN. You can check if SCSNODE is defined by
              using the following command:

              $ WRITE SYS$OUTPUT F$GETSYI("NODENAME")
              SPIELN
              $

              In this example, SPIELN is the SCSNODE name. If the SYSGEN
              parameter SCSNODE is not defined then no node name is
              returned.

              Another way of checking SCSNODE is to go into SYSGEN and
              execute the following command:

              $ MCR SYSGEN
              SYSGEN>  SHOW SCSNODE
              Parameter Name   Current    Default    Min.     Max.    Unit  Dynamic
              --------------   -------    -------   -------  -------  ----  -------
              SCSNODE          "SPIELN  " "    "    "    "   "ZZZZ"   Ascii
              SYSGEN> EXIT
              $

              In this example, SPIELN is the SCSNODE name.

        Installing Disk File Optimizer Software
        1.2 Preparing to Install the Disk File Optimizer Software


              If the node is a standalone node, it does not require that
              SCSNODE be defined. However, if you wish to, you can define
              it in SYS$SYSTEM:MODPARAMS.DAT as follows and then do an
              AUTOGEN:

              SCSNODE="SPIELN"
              SCSSYSTEMID=9112

              If the node is running DECnet, it will have a logical
              SYS$NODE defined. You can check to see if the logical
              SYS$NODE is defined using the following command:

              $ SHOW LOG SYS$NODE
                 "SYS$NODE" = "SPIELN::" (LNM$SYSTEM_TABLE)
              $

              In this example, SPIELN is the SYS$NODE name.

        1.2.8 Stop the Scheduler on Defrag Plus Installations

              If you are running a previous version of the Disk File
              Optimizer, then shut down the Scheduler software on all
              nodes before installing the new version of Defrag or Defrag
              PLUS software.

              Use SYSMAN to shut down the Scheduler software or execute
              the following command on all nodes:

              $ @SYS$MANAGER:DFG$STOP_SCHEDULER.COM

        1.2.9 Execute SYS$SYSTEM:SETFILENOMOVE.COM

              Before you run the Disk File Optimizer, execute
              SYS$SYSTEM:SETFILENOMOVE.COM against all OpenVMS operating
              system disks on your cluster. SETFILENOMOVE.COM identifies
              all system files that must not be moved because they are
              accessed without the file system. When you run this command
              file, it sets the NOMOVE bit in the file header for the
              identified files. If you do not run this command procedure,
              system files could be moved that would be "lost" to the
              accessing processes.

              This procedure marks certain critical system files with the
              NOMOVE attribute. This anchors these files to the disk; any
              attempt to relocate them using the XQP MOVEFILE function
              fails.

                1.2 Preparing to Install the Disk File Optimizer Software


              While attempting to execute SETFILENOMOVE.COM, you may
              receive several errors similar to the following:

              %SET-E-READERR, error reading <file name>
              -SYSTEM-W-ACCONFLICT, file access conflict

              To set the NOMOVE attribute on these files you must boot
              from another system, such as the distribution CD, and then
              execute SETFILEMOVE.COM against the disk. However, these
              files may already have the NOMOVE attribute set. Use the
              DIRECTORY/FULL command to determine if the NOMOVE attribute
              was already set.

              If the NOMOVE attribute is not set and you cannot boot from
              another system disk, you should be all right because the
              file is open when the system is booted. Disk File Optimizer
              does not defragment or move open files.

              To use this SETFILENOMOVE.COM procedure, you must specify
              the file name as P1 on the command line. For example:

              $ @SYS$SYSTEM:SETFILENOMOVE $1$DKB100:

        1.2.10 Registering the Disk File Optimizer Software License

              When you are installing Disk File Optimizer software for
              the first time, you must register the Disk File Optimizer
              software license.

                   complete.

                   OPTIONS N indicates you want to see the release
                   notes. If you do not include this parameter, VMSINSTAL
                   does not ask you about the release notes. Review the
                   release notes before proceeding with the installation
                   as they could contain additional installation
                   information.

                   OpenVMS operating system disks before you install
                   the Disk File Optimizer software, files on your system
                   disks could be moved. This would cause access problems
                   for utilities that access files directly rather than
                   through the file system. Refer to Section 1.2.9 for

                   At this point, the installation procedure displays a
                   number of informational messages that report on the
                   progress of the installation. There are no further
                   questions. If the installation procedure has been
                   successful up to this point, VMSINSTAL moves the new
                   or modified files to their target directories, updates
                   Help files, and updates DCL tables, if necessary. If
                   you chose to have files purged, that work is done now.
                   The following message is displayed:

                   No more input is required to complete this installation.  From this

                   point it proceeds automatically.

                   The following messages are displayed when the
                   installation procedure converts the RMS database to
                   do away with index key compression:

                           Attempting to convert your RMS database so there is no index key

                           compression.  This requires converting the database.  The old

                           database files will be renamed to:

                               DFG$DATABASE:DFG$DB_OLD.DAT

                           After you are satisfied with the installation, you may wish to delete

                           these files.

                   After the files have been moved, the installation
                   procedure starts a scheduling process on the
                   installing node. The name, ID, and log file for this
                   process are displayed:

                   %RUN-S-   Installing Disk File Optimizer Software 1-23

                   Scheduler log file: DFG$DATABASE:DFG$XXXX.LOG

                   The name of the scheduler process is DFG$_XXXX,
                   where XXXX is the node name where the scheduler is
                   executing.

                           ___________________ Note ___________________

                           The name of the node comes from either the
                           SYSGEN parameter, SCSNODE, or if SCSNODE
                           is undefined, from the system logical
                           name, SYS$NODE. At least one of these
                           must indicate a valid node name or the
                           defragmentation software will not work
                           correctly.

              If errors occur during the installation or when the IVP
              is running, VMSINSTAL displays failure messages. If the
              installation fails, the following message is displayed:

              %VMSINSTAL-E-INSFAIL, The installation of DFG Version
              V2.9
              has failed.

              If the IVP fails, the following messages are displayed:

              The DFG Version V2.9 Installation Verification Procedure failed.

              %VMSINSTAL-E-IVPFAIL, The IVP for DFG Version
              V2.9 has failed.

              conditions exist, take the appropriate action as described
              in the message.

        1.4 After Installing the Disk File Optimizer

              Perform the following tasks after installing the Disk File
              Optimizer:

              o  Run the IVP separately to verify the installation

              o  Edit the system startup and shutdown files

              o  Make the Disk File Optimizer software usable on a
                 VMScluster system

              o  Resolve database errors

              o  Delete old copies of the database files

              o  Verify account requirements

              o  Report any problems

        1.4.1 Running the IVP Separately

              You usually run the Installation Verification Procedure
              (IVP) during the installation by responding YES to the
              question:

                 * Do you want to run the IVP after the installation [YES]?

              If you did not run the IVP during the installation, or
              if you want to run the IVP separately to confirm the
              integrity of installed files, execute the IVP by entering
              this command:

              $ @SYS$TEST:DFG$IVP.COM

              Requirements:

              The Disk File Optimizer software must be running on the
              system where the IVP is executed.

        1.4 After Installing the Disk File Optimizer


        1.4.2 Editing the System wide Command Files

              System_startup:

              You must edit the system startup procedure to ensure
              automatic startup of the Disk File Optimizer software each
              time the system boots. Add the following line to

              SYS$MANAGER:SYSTARTUP.COM:
              $ @SYS$MANAGER:DFG$STARTUP.COM

              System_shutdown:

              You can modify the system shutdown file to provide for an
              orderly shutdown of the Disk File Optimizer. To do this,
              add the following line to SYS$MANAGER:SYSHUTDWN.COM:

              $ @SYS$MANAGER:DFG$SHUTDOWN.COM

        1.4.3 Making the Disk File Optimizer Work on a VMScluster System

              To make the Disk File Optimizer available on all nodes
              of the cluster, you should ensure that all nodes have
              the latest version of DCLTABLES.EXE installed. You can
              do this by using SYSMAN or by logging in to each node in
              the cluster and entering the following command:

              $ INSTALL REPLACE SYS$COMMON:[SYSLIB]DCLTABLES.EXE

        1.4.4 Deleting Old Copies of the RMS Database Files

              If you upgraded the Defrag PLUS variant of Disk File
              Optimizer, there are seven old files on your disk:

              o  DFG$DATABASE:DFG$DB_OLD.DAT

              o  DFG$DATABASE:DFG$FILE_OLD.DAT

              o  DFG$DATABASE:DFG$GENERAL_OLD.DAT

              o  DFG$DATABASE:DFG$NODE_OLD.DAT

              o  DFG$DATABASE:DFG$QUEUE_OLD.DAT

              o  DFG$DATABASE:DFG$SCRIPT_OLD.DAT

              o  DFG$DATABASE:DFG$VOLUME_OLD.DAT

              You can delete these files.

              If you are upgrading from Disk File Optimizer V1.0 and have
              saved the data in your database, you must restore it. If
              you saved your database data as described in Section 1.2.1,
              you can load it into your new RMS database using the
              following command:

              $ @LOAD_DB

        1.4.6 Verifying Account Requirements

              The following privileges are required to run the Disk File
              Optimizer software:

              o  BYPASS

              o  CMKRNL

            run prior to the conclusion of this procedure by answering "YES" to the
            IVP prompt or it can be invoked after the installation as follows:

        @SYS$TEST:DFG$IVP.COM

        * Do you want to run the IVP after the installation [YES]?

            You must run the @SYS$SYSTEM:SETFILENOMOVE.COM command procedure against

            procedure and to later run the defragmentation software on the system
            disk could result in corruption of the system disk.
