Finding Existing
SCSI Controllers
and Devices
6
The files
/usr/adm/hwconfig and /var/adm/messages
list the devices found
during boot up of Open Server. The current SCSI controllers can be found
using the command:
grep adapter /usr/adm/hwconfig 6
This command produces output similar to:
%adapter 0x6400–0x64FF 11 type=alad ha=0
bus=0 id=7 fts=st0.
The current tape drives can be found using the command:
grep tape /usr/adm/hwconfig
Note:
We suggest using the AIX commands
.backup
and
.restore
when transferring data to and from the LTO-2 Half-
Height Tape Drive. These commands transfer data more
quickly than other commands such as tar and cpio.
• For cpio we suggest a blocking factor of 128.
• For tar we suggest using the .N option and a factor of
128.
• Some older systems with poor video controllers may
experience a reduction in performance when using
the .v option, which prints the path names on the
standard console during the backup. Unless there is a
real need to see the filenames as they are backed up we
suggest not using the .v option.
• For commands that use density and tape size settings
the tape density is 124,000 bpi and the tape length is
1800 feet.
