Installing the Software Drivers NetWare ASPI Support The Readme.com on the Novell Software Support Diskette (NSSD) outlines the specific drivers you need to support ASPI tape backup applications. NWASPI is used by some third party software vendors such as Veritas Backup Exec in versions prior to BackupExec for Netware Version 9.0. After 9.0 NWASPI will be replaced by the Veritas driver BECDM.CDM. This driver is loaded automatically when you start the backup application. If you are using NWASPI you can load it from the C:\nwserver\drivers directory. It is recommended that you download and use the latest NWASPI driver from the Novell website. Refer your third party vendor documentation for specific details regarding how tape drivers are loaded. Compaq Tru64 UNIX The Compaq Tru64 UNIX operating system uses Dynamic Device Recognition (DDR), which allows the operating system to recognize the AIT drive without a software tape device driver.

NetWare ASPI Support
The

specific drivers you need to support ASPI tape backup applications.
NWASPI is used by some third party software vendors such as Veritas Backup Exec in
versions prior to BackupExec for Netware Version 9.0. After 9.0 NWASPI will be
replaced by the Veritas driver BECDM.CDM. This driver is loaded automatically
when you start the backup application. If you are using NWASPI you can load it from

Refer your third party vendor documentation for specific details regarding how tape
drivers are loaded.
Compaq Tru64 UNIX
The Compaq Tru64 UNIX operating system uses Dynamic Device Recognition
(DDR), which allows the operating system to recognize the AIT drive without a
software tape device driver.
If the following message is seen on any version of Compaq Tru64 UNIX, you should
update the DDR database to include the new device parameters.
ctape_ioctl: unmapped scsi density code (0x30)-DDR
entry needed
The SCSI tape drive for True64 UNIX provides a standard tape drive interface. This is
the tape driver for any Compaq SCSI tape device connected to a True64 UNIX
operating system. Facilities are provided to allow the addition of SCSI tape drives to
the system.
