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.
