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
