HP LTO Ultrium 6 tape drives UNIX, Linux and OpenVMS configuration guide

Actions > Create Device Files > Show Device Files

4. When you have exited sam, run ioscan to see the tape drive:

%/sbin/ioscan -fnC tape

All default device files displayed have compression enabled.

NOTE: HP recommends the ‘Berkeley’ device files of most applications:

cXtYdZBESTnb = Berkeley, no rewind, best available density

cXtYdZBESTb = Berkeley, with rewind, best available density

where:

X = card number

Y = target number

Z = LUN number

For HP-UX 11i v3 (HP-UX 11.31)

1. Start up the SMH web-based interface:

% smh –w

This will attempt to launch a web browser. Mozilla browser

is the default when HP-UX 11i

v3 is installed.

2. From the SMH Tools page (see Figure 3 (page 8)), select Manage Peripheral Devices from

the Peripheral Devices section.

3. Select tape from the Class drop-down box on the HP-UX Peripheral Device Tool page. Select

the tape device (radio button) requiring device files from the resulting list. If device files are

not already present this will be indicated under the Properties header (see Figure 5)

Figure 5 Selecting a tape device to create its device files (Agile View)

4. From the right-hand panel on the HP-UX Peripheral Device Tool page, click on Reinstall Device

Files. At the next page, click the Reinstall button. When the browser returns to the HP-UX

Peripheral Device Tool page, click the Refresh button one or more times until the list of device

files appears under the Properties header.

Using large block sizes

A block size no larger than 256 KB (262144 bytes) is strongly recommended when working with

HP-UX and tape or VTL devices. Backup applications should be configured to work with I/O block

4. If Mozilla is being invoked for the first time you may be asked to agree to license terms for the software.

5. Depending on how SMH was last used the HP-UX Peripheral Device Tool page will display either the Agile View or the

Legacy View as described at the beginning of this chapter. To switch between these views use the Toggle Global Device

View link on the right hand side of the HP-UX Peripheral Device Tool page. In this chapter, the Agile View is assumed.

The process is similar for the Legacy View.
