The SCSI Passthru Driver (ovpass)

Read this topic if you plan to use SCSI-controlled robotic peripherals or HP 1.2 gigabyte or

equivalent model magneto-optical disk drives.

If you are using an API robot, such as an IBM Automatic Tape Library (ATL), refer to the

NetBackup Media Manager Administration guide for information on configuring the

robotic peripheral.

When communicating with SCSI-controlled robotic peripherals on an IBM AIX system,

Media Manager utilizes a SCSI passthru driver called ovpass.

The SCSI passthru driver and SCSI passthru device paths are required by NetBackup for

full feature support. Performance will be degraded if SCSI passthru is not provided. The

passthru driver is used

◆ By avrd and robotic processes to scan drives.

◆ By NetBackup and Storage Migrator for locate-block positioning.

◆ By NetBackup and Storage Migrator for SAN error recovery.

◆ By NetBackup and Storage Migrator for Quantum SDLT performance optimization.

◆ By NetBackup and Storage Migrator for SCSI reserve/release.

◆ To set the optical drive type (as explained in “Setting the HP Optical Drive Type in

Nonvolatile Memory” on page 48).

◆ By the NetBackup device configuration GUIs to collect robot and drive information.

◆ To collect TapeAlert information from tape devices allowing support of functions

such as tape drive cleaning.

◆ For WORM tape support.

◆ Future NetBackup features and enhancements

The ovpass driver is also used to set the optical drive type, as documented in “Setting the

HP Optical Drive Type in Nonvolatile Memory” on page 48. ovpass is not required if the

only device being used is the IBM 3590 B11 tape stacker.

Note You cannot use smit to configure ovpass device files.

▼ To install the ovpass driver
