mtx Tape Library Tool 20

All the matching initializations are collected in the order they are defined in

the

stinit.def file. This means that you can define global parameters that apply

to all devices by placing them before all tape device definitions in

stinit.def. For

an example, see

# Global Keywords and Values in Appendix C – Sample

stinit.def Definitions File.

mtx Tape Library Tool 0

mtx is a tape library media management tool. This section shows you how to

determine if

mtx is installed and how to install it.

The use of

mtx is beyond the scope of this document.

Verifying mtx is Installed0

To verify mtx is installed, execute the following command:

# rpm -qa mtx

This command returns the name of the package followed by a version

number (for example, RHEL2.1 returns

mtx-1.2.13-1).

If no information is returned, mtx is not installed on the system. To install

mtx, see Installing mtx

Keyword Description

block[size]=value The tape block size can be set to value bytes. Quantum

recommends using the default block[size] = 0,

signifying variable block mode.

comp[ression]=

value

Compression of the data by the drive is enabled if

value

does not equal zero. Note that the tape driver cannot

enable compression for all drives that can compress

data. Some drives define compression using density

codes. Quantum does not use density codes and

requires compression to be enabled.

The compression default setting is determined by

stinit.def. If stinit.def is not found, compression defaults

to ON.

Note:

mtx rpm is not included in the Red Hat Enterprise Linux 3.0. If you

are running RHEL 3.0, you will not be able to use the

mtx module.
