Configuring Tape Drives

Adding Nonstandard Tape Drives

This topic applies to the following drive types:

◆ HP LTO

◆ Seagate LTO

◆ STK 9840

Some types of tape drives require changes to the kernel before you can use them on Tru64.

▼ To change the kernel

Refer to the following man pages for more information on Dynamic Device Recognition

(DDR):

◆ ddr.dbase(4)

◆ ddr_config(8)

1. Add the appropriate device-specific entries to the /etc/ddr.dbase file (see

“Device-Specific Entry for HP Ultrium 460” on page 77 and the other device entries

that follow).

2. Compile the /etc/ddr.dbase file using the ddr_config (Dynamic Device

Recognition) utility to create the ddr.db file.
