    My previous SUMMARY contained an error, and was
    misleading in how to correctly update the ddr.dbase
    file for an SDLT320 tape drive.
    To the best of my knowledge, the following steps are
    what is required to update the ddr.dbase entry for
    an SDLT320 tape drive (asterisks mark steps where
    I have filled in some things that are not mentioned in
    the release notes, but that proved to be necessary
    for me to update the ddr.dbase file).

    (1) Copy the existing /etc/ddr.dbase file to a holding file for
    safe keeping.

    *(2a) Open the ddr.dbase file with an editor. There are two
    sections near the top of the file that are both labeled GLOBAL -
    go to the second one of these sections and find the following
    line:
    "scsi_density_table_size = 0x49"
    and edit this line to read
    "scsi_density_table_size = 0x4a"
    (Because you are going to add one new entry in the next step.)

    *(2b) In the table of entries under the above heading add
    the following entry at the end of the table:

    scsi_tape_density[0x49] = "190000_bpi" 190000 0

    The line right above it should be:
    scsi_tape_density[0x48] = "131000_bpi" 131000 0

    *(3) Add the following SCSIDEVICE entry after the current entry
    for "SuperDLT1"

               SCSIDEVICE
               #
               # Matches SDLT320
               #
               Type = tape
               Name = "COMPAQ" "SDLT320"
               #
               #
               PARAMETERS:
               TypeSubClass = tk
               TagQueueDepth = 0
               MaxTransferSize = 0x0fffffb # (16MB - 4)
               ReadyTimeSeconds = 120 # seconds

               DENSITY:
               #
               DensityNumber = 0
               DensityCode = 0x48
               CompressionCode = 0x1
               Buffered = 0x1

               DENSITY:
               #
               DensityNumber = 1,5
               DensityCode = default
               CompressionCode = 0x1
               Buffered = 0x1

               DENSITY:
               #
               DensityNumber = 2,4,6,7
               DensityCode = default
               CompressionCode = 0x0
               Buffered = 0x1

               DENSITY:
               #
               DensityNumber = 3
               DensityCode = 0x48
               CompressionCode = 0x0
               Buffered = 0x1

    (4) FROM THIS POINT ON FOLLOW STEPS 4 THROUGH 7 AS DESCRIBED
    IN THE V51.B RELEASE NOTES.
