Linux Device Driver (lin_tape) target device, for example, the last number in the previous mapping. Currently, the zfcp device driver does not support dynamically removing the attached devices. If you need to remove the tape devices from the system, do ″rmmod zfcp″. Then you can delete the entry in /etc/modules.conf and reload zfcp, or reload zfcp first and dynamically add the devices you want. After you have done all the mapping, if you can see all of the attached tape devices in /proc/scsi/scsi, you have successfully attached those devices to your system. Next you may install the lin_tape device driver. Refer to the ""Installation Procedure" on page 97″ section in this chapter for the instructions on how to install lin_tape. Uninstall Procedure Note: All tape devices that use the lin_tape driver must be closed and cannot be in use when lin_tape is uninstalled or the uninstall fails. Run the following command: >rpm -e lin_tape ---to remove Tape Drive, Media, and Device Driver Parameters This chapter describes the parameters that control the operating modes of the IBM Linux Tape and Medium Changer Device Driver.

Tape Drive, Media, and Device Driver Parameters
This chapter describes the parameters that control the operating modes of the IBM
Linux Tape and Medium Changer Device Driver.
Configuration Parameters
The configuration parameters are used to set the operating mode of the tape drive
and device driver when a device is opened. The installation defaults are provided
for all parameters initially. Some of these parameters can be queried and set by
IBMtapeutil
,
Query/Set Tape Parameters
in the menu. These parameters are kept
on reopen, but are always restored back to the default values when the lin_tape
device driver is reinstalled.
Note:
This is performed using tape diagnostic and utility functions.
The nonchangeable configuration parameters are:
v
Autoloading
v
Density code
v
Emulate autoloader
v
Hook word
v
Maximum block size
v
Minimum block size
v
Medium type
v
Read SILI bit
v
Record space mode
v
Volume ID for logging
v
