Command ReferenceA-115
NAME
tape - information on filer tape interface
DESCRIPTION
The filer supports up to four local tape drives (tape drives connected directly to
the system). The tape drive interface follows a UNIX-like device name allowing
use of a rewind, norewind or unload/reload device. The format of a filer tape
device name is crstud where:
cuse n to specify the norewind device, use u to specify the unload/reload
device, or no flag to specify the rewind device. The norewind device will
not rewind when the tape device is closed. The unload/reload device is
used with sequential tape loaders and will unload the current tape volume
and attempt to load the next tape volume (note that the server will wait up to
one minute for the next volume to become ready before aborting the reload
of the next volume). The rewind device will rewind the tape volume to
beginning-of-tape on close.
rst the rst portion of the device name is always present and specifies that you
are requesting a SCSI tape device.
uthe logical unit number of the tape drive to use.
dthe density (or format) to use for tape write operations.
The density specifications for an Exabyte 8505 8mm drive are:
lExabyte 8200 format, no compression
mExabyte 8200 format with compression
hExabyte 8500 format, no compression
aExabyte 8500 format with compression
EXAMPLES
The sysconfig -t command will display the supported tape drives on your system
and the device names associated with each tape device along with the deviceî‚’s
density, or format. The following is an example of the output from a sysconfig
command on a filer with one tape device attached:
filer> sysconfig -t
