        PHKL_9372: PANIC

Path Name:  /hp-ux_patches/s700/10.X/PHKL_9711

Symptoms:
        PHKL_9711:
        Each time edquota -t is invoked for a VxFS file system, it
        resets the previously defined file system time limit back
        to default (7 days).

        PHKL_9372:
        Panic:  "data  page  fault"  when  using  fsadm to  resize a
        mounted VxFS filesystem with disk quotas.

Defect Description:
        PHKL_9711:
        VxFS quota routine vx_getquota() resets the time limit for
        root because it thinks root should not have a quota limit.
        Somehow it ignores the fact that the timelimit fields in
        root's dqblk structure are used to store the file system
        time limit.

        PHKL_9372:
        Resizing  VxFS  filesystems  online  effectively  does quick
        unmounts and remounts of the filesystem,  switching  quickly
        between  the  two  different   data  areas   containing  the
        filesystem  structure   information.  The  VxFS  disk  quota
        tracking structures were not updated during the switch, with
        the end  result  that  the disk  quota  code  was  accessing
        invalid  memory.  The  fix  was to  update  the  disk  quota
        structures during the switch.

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 PHKL_9711

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

                swinstall -x autoreboot=true -x match_target=true \
                        -s /tmp/PHKL_9711.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/PHKL_9711.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.

        By default swinstall will archive the original software in
        /var/adm/sw/patch/PHKL_9711.  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 PHKL_9711.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/PHKL_9711.depot of=/dev/rmt/0m bs=2k
