Finding Existing
SCSI Controllers
and Devices
6
Before installing the LTO-3 Tape Drive, ensure that the requisite SCSI
controllers and device drivers are installed on your system.
To find existing SCSI controllers execute the command:
dmesg | grep SCSI
Note: Not all of the SCO “tape” commands will operate or be
applicable to the LTO-3 Tape Drive (execute the command
.man tape. for the specifics on how the tape command works).
The following tape commands are not available for use with
the LTO-3 Tape Drive:
getcomp
,
setcomp
(the LTO-3 Tape
Drive will always compress the data before writing the data to
tape under SCO Open Server 5.0.x),
partition
,
setpart
,
getpart
,
getspeed
,
setspeed
,
rsm
,
wsm
. The following tape commands
are available for use with the LTO-3 Tape Drive:
status
,
load
,
reset
,
rewind
,
retention
,
getblk
,
setblk
,
unload
,
eod
.
When using the GUI Backup Manager utility set the block size
to 32768 minimum, 65536 preferred. When using commands
such as
tar
we suggest using the tape command to set the block
size to 512 and then using a blocking factor of 80 for the tar
command. For commands that use density and tape size
settings the tape density is 124,000 bpi and the tape length is
1800 feet.
