For TSM to use a device, you must configure the appropriate device driver (add it to the kernel).
For procedures to configure device drivers, see the documentation for the operating system.
To identify and work with removable media devices, TSM needs each device's name, the special file name.
For tape drives supported by the standard HP-UX device drivers, after you configure the device drivers the operating system automatically assigns the special file names during system start-up. A single drive can have multiple special file names, depending on the format and recording density that the drive supports. Select the device name to use in defining the drive to TSM based on the format and density that you want TSM to use. For example, one device may have all of the following special file names:
The different names represent different recording formats, densities, and operating characteristics such as data compression. For example, you might choose the name /dev/rmt/c1t0d0BEST to have TSM use the best recording format and density available on the drive.
To see these file names, you can use the HP-UX System Administration Manager (SAM), or use the ioscan command. For example, to see the device special files available for tape drives, enter the command:
> /usr/sbin/ioscan -fkn -C tape
Also useful is the lssf command to get more information about a specific device special file name. See the documentation for the operating system.
For details about special file names, see the documentation for the operating system.
For an automated tape library, the special file names for the drives in the library are created and used as described above. For the library itself, you create the special file name when you set up a SCSI pass-through driver. For example, you might create the special file /dev/tsm/library for the library. Use this special file name as the device name when defining the library to TSM.
TSM supports the spt, sctl, and schgr SCSI pass-through device drivers. See the HP-UX documentation for scsi_pt, scsi_ctl, and autochanger, respectively, for information on installing and configuring the various pass-through device drivers.
For IBM 3570 and 3590 devices, see IBM SCSI Device Drivers: Installation and User's Guide for instructions on how to install the device drivers.
After completing the procedure in the manual, a set of special file names are available for each device. To see the special file names, enter the command:
> ioscan -kfn -C tape
/dev/rmt/xm
where x is a number. The name may have additional characters (n, b) at the end to indicate different operating characteristics.
Enter the device name that you select in the Device Name field for the drive on the worksheet.
For an IBM 3494 Tape Library Dataserver, use the information in IBM SCSI Device Drivers: Installation and User's Guide to install the driver. The driver is the IBM Tape Library Driver for HP-UX, which consists of the lmcpd (a daemon) and other components.
To determine the name to use to define the library to TSM, check what you entered in the /etc/ibmatl.conf file for the library's symbolic name. Use this information to complete the Device Name field on your worksheet.
For example, if the symbolic name for the library in the /etc/ibmatl.conf file is 3494a, enter that name on the worksheet in the Device Name field for the library.
The drives that are in the library are set up separately. See Installing Device Drivers for IBM 3570 and 3590 Tape Drives.
