Repost: 96/04/24
        The patch documentation was modified to discuss the limitations of the
        ISO-9660 support.

Hardware Platforms - OS Releases:
        s700: 9.03 9.05 9.07

Products: N/A

Filesets:
        KERN-BLD

Automatic Reboot?: Yes

Status: General Release

Critical: No

Path Name:  /hp-ux_patches/s700/9.X/PHKL_6075

Symptoms:
        PHKL_6075:
        No option to convert a ISO-9660 CDROM filename from
        "FILENAME;VERSION" to lower case "filename".

Defect Description:
        PHKL_6075:
        HP-UX does not provide a mount option which will convert
        the ISO-9660 filename from "FILENAME;VERSION" format
        to lower case "filename" like most of the industry Unix
        platforms do. PC's and non-HP clients cannot use the
        ISO-9660 CD-ROM exported from a HP-UX NFS server because
        symbolic link, the only work-around, is not available
        on these systems.

        The fix adds two global kernel variables to the cdfs
        operation to provide the filename convertion
        functionality. These variables can be turned on and off
        using adb after the patch is installed.

        The kernel variables which need to be modified are:

        cdfs_convert_case - Set this to 1 to display filenames
                            in lower case.

        cdfs_zap_version -  Set this to 1 to suppress version
                            number in filenames.

        If you want the variables to be set in the kernel file
        /hp-ux so the function remains after a system reboot,
        type the following:

        echo "cdfs_convert_case?W 1" | adb -w /hp-ux /dev/kmem
        echo "cdfs_zap_version?W 1" | adb -w /hp-ux /dev/kmem

        Or you can modify the memory only by typing:

        echo "cdfs_convert_case/W 1" | adb -w /hp-ux /dev/kmem
        echo "cdfs_zap_version/W 1" | adb -w /hp-ux /dev/kmem

                  -------  N O T E S -------

        1. Limited by the scope of a patch, this fix does not
           add the functionality to mount_hfs(1M) command to
           allow selective case conversion for individual
           CDROMs. Setting the global kernel variable
           forces conversion on all mounted CDROMs. If your
           CDROM is not in ISO-9660 format or you have more
           than one type of CDROMs mounted, the files on
           the nonISO-9660 CDROMs may not be recognizable.
           You will need to use adb to reset the variables
           in order to access these CDs:

        echo "cdfs_convert_case/W 0" | adb -w /hp-ux /dev/kmem
        echo "cdfs_zap_version/W 0" | adb -w /hp-ux /dev/kmem

           We recommend you put the above lines in a script.

        2. This patch does not provide support for RockRidge
           Extensions.

        This patch only offers an interim solution. The
        mount_hfs(1M) case conversion option is available
        in hp-ux 10.10.

        1. Back up your system before installing a patch.

        2. Copy the patch to your /tmp directory and unshar it:

                cd /tmp
                cp patch_source/PHKL_6075 .
                sh PHKL_6075

        3. Become root and run update:

                /etc/update -s /tmp/PHKL_6075.updt PHKL_6075

        Update moves the original software to
        /system/PHKL_6075/orig.  Keep this file to recover from any
        potential problems.  You should move the .text file to
        /system/PHKL_6075 for future reference.

        To put this patch on a magnetic tape and update from the
        tape drive, use dd:

                dd if=PHKL_6075.updt of=/dev/rmt/0m bs=2048
