Path Name:  /hp-ux_patches/s700_800/10.X/PHCO_7817

Symptoms:
        PHCO_7817:
        If the system is booted into LVM maintenance mode, doing an
        fsck of a device defined to have an HFS file system will
        produce the error message

        DeviceName(): Cannot determine name of device major=??,
                                                      minor=??

        where the major and minor numbers may differ, depending on
        the system.  This prevents the fsck from succeeding.

Defect Description:
        PHCO_7817:
        The problem will only appear when the system is booted into
        LVM maintenance mode, which is ususally used only for system
        repair.

        fsck tries to determine if the device that fsck was invoked
        upon is a swap device, but in this mode, the device numbers
        are not mapped where the swap device checking routine can
        determine this information.  It mistakenly exits instead
        of letting the user continue if desired.

Installation Instructions:
        Please review all instructions and the Hewlett-Packard
        SupportLine User Guide or your Hewlett-Packard support terms
        and conditions for precautions, scope of license,
        restrictions, and, limitation of liability and warranties,
        before installing this patch.
        ------------------------------------------------------------
        1. Back up your system before installing a patch.

        2. Login as root.

        3. Copy the patch to the /tmp directory.

        4. Move to the /tmp directory and unshar the patch:

                cd /tmp
                sh PHCO_7817

        5a. For a standalone system, run swinstall to install the
            patch:

                swinstall -x autoreboot=true -x match_target=true \
                        -s /tmp/PHCO_7817.depot

        5b. For a homogeneous NFS Diskless cluster run swcluster on the
            server to install the patch on the server and the clients:

                swcluster -i -b

            This will invoke swcluster in the interactive mode and
            force all clients to be shut down.

            WARNING: All cluster clients must be shut down prior to the
                     patch installation.  Installing the patch while the
                     clients are booted is unsupported and can lead to
                     serious problems.

            The swcluster command will invoke an swinstall session in which
            you must specify:

                alternate root path  -  default is /export/shared_root/OS_700
                source depot path    -  /tmp/PHCO_7817.depot

            To complete the installation, select the patch by choosing
            "Actions -> Match What Target Has" and then "Actions -> Install"
            from the Menubar.

        5c. For a heterogeneous NFS Diskless cluster:

                - run swinstall on the server as in step 5a to install
                  the patch on the cluster server.

                - run swcluster on the server as in step 5b to install
                  the patch on the cluster clients.  The cluster clients
                  must be shut down as described in step 5b.

        By default swinstall will archive the original software in
        /var/adm/sw/patch/PHCO_7817.  If you do not wish to retain a
        copy of the original software, you can create an empty file
        named /var/adm/sw/patch/PATCH_NOSAVE.

        Warning: If this file exists when a patch is installed, the
                 patch cannot be deinstalled.  Please be careful
                 when using this feature.

        It is recommended that you move the PHCO_7817.text file to
        /var/adm/sw/patch for future reference.

        To put this patch on a magnetic tape and install from the
        tape drive, use the command:

                dd if=/tmp/PHCO_7817.depot of=/dev/rmt/0m bs=2k
