thanks, John Francini
This work fine!!!!!
Interestingly, there was a service advisory about this that just came by a
couple of days ago in my e-mail. It describes how to edit the DDR table to
support the drive. The relevant instructions are as follows:
The human-readable version of the DDR database resides in the file
/etc/ddr.dbase.
As root, edit the file with a text editor, such as vi or Emacs. First, find
the string (near the beginning) that says:
scsi_density_table_size = 0x42
and change it to read:
scsi_density_table_size = 0x49
Locate the actual density table, which is a bit further down in the file.
After the last entry, which should begin "scsi_tape_density[0x41]", add the
following lines:
scsi_tape_density[0x42] = "density_code_42" 0 0
scsi_tape_density[0x43] = "density_code_43" 0 0
scsi_tape_density[0x44] = "density_code_44" 0 0
scsi_tape_density[0x45] = "density_code_45" 0 0
scsi_tape_density[0x46] = "density_code_46" 0 0
scsi_tape_density[0x47] = "density_code_47" 0 0
scsi_tape_density[0x48] = "131000_bpi" 131000 0
I've indented them for clarity; don't indent them in the ddr.dbase file.
Now you need to add the actual SCSI Device Data for the SDLT drive to the
table. To do this:
1. Locate the "DEVICE DATA" section of the DDR table.
2. Below that, locate the "TAPES:" section of the device data. Before the
first existing SCSIDEVICE entry (but after the comment block describing the
entry format), add the following entry:
SCSIDEVICE
#
# Matches SuperDLT1
#
Type = tape
Name = "COMPAQ" "SuperDLT1"
#
#
PARAMETERS:
TypeSubClass = tk
TagQueueDepth = 0
MaxTransferSize = 0x0ffffff # (16MB - 1)
ReadyTimeSeconds = 120 # seconds
DENSITY:
#
DensityNumber = 0,2 # rmt*l, rmt*m
DensityCode = default
CompressionCode = 0x0
Buffered = 0x1
DENSITY:
#
DensityNumber = 1,3 # rmt*h, rmt*a
DensityCode = default
CompressionCode = 0x1
Buffered = 0x1
Again, do not indent the lines in the file; I've indented them for
readability.
Save the file and exit.
Now you need to re-create the ddr.db file (the binary device data
recognition database) using ddr_config(8) as follows:
# ddr_config -c
ddr_config is described in the Tru64 system admin manual, and is also
documented in a man page.
You should now be able to use the tape drive without seeing any messages on
the console or in the /var/adm/messages file.
