To create device files using
mksf
:
NOTE:
This method is not recommended.
1.
Run
insf
as follows:
% /sbin/insf -C tape
2.
Create the device files for the devices using the
mksf
command as follows:
% /sbin/mksf -d stape -I <instance> [-n] [-u] /dev/rmt/X<name>
where:
See the man page (
man 1m mksf
) for other options of the
mksf
command. The
stape
section
covers the SCSI tape driver options. The man page
man 7 mt
describes the long filenames used
in HP-UX 10. x and later.
Example:
To create a device file with the following characteristics:
Argument Description
-d stape
Specifies the SCSI tape driver
-I <instance>
Specifies the tape drive’s hardware address via the instance of the SCSI tape
driver. The first instance is 0, the second 1, and so on.
[-n]
Specifies no rewind; absence of this parameter indicates rewind mode
[-u]
Specifies Berkeley mode; absence of this parameter indicates AT&T mode.
Berkeley and AT&T modes differ in their read-only close behavior:
• In Berkeley mode, the tape position will remain unchanged by a device
close operation.
• In AT&T mode, a device close operation will cause the tape to be
repositioned just after the next tape filemark (the start of the next file).
In most cases, Berkeley mode should be used.
/dev/rmt/X<name>
Specifies the path of the device file, where:
X
Specifies the tape device identifier. Use the next available
identifier. You can examine the contents of
/dev/rmt
using the
ls
command to determine which identifiers have already been
used.
<name>
Specifies the short name (in HP-UX 9.x-style) of the device file:
mnb
No rewind, compression disabled, Berkeley-mode device
hnb
No rewind, compression disabled, Berkeley-mode device
mnb
No rewind, compression disabled, Berkeley-mode device
hnb
No rewind, compression enabled, Berkeley-mode device
