Veritas NetBackup™ Device Configuration Guide

Observe the following points when you configure the operating system:

• Verify that NetBackup supports your server platform and devices. Download the NetBackup hardware and the operating system compatibility lists.

  http://www.netbackup.com/compatibility

• For SCSI controlled libraries, NetBackup issues SCSI commands to the robotic devices.

  For NetBackup to function correctly, the properly named device files must exist, as follows:

  • NetBackup installs its own pass-through driver, the SCSI generic sg driver. You must configure this driver properly to create device files for any device NetBackup uses.

  • The Solaris tape and disk driver interfaces also create a device file for each tape drive device. These device files must exist for all read or write I/O capability.

• Verify that the Solaris st driver is installed.

• Verify that the devices are configured correctly. To do so, use the Solaris mt command and the NetBackup /usr/openv/volmgr/bin/sgscan utility.

  For the tape drives that you want to share among NetBackup hosts, ensure that the operating system detects the devices on the SAN.

• When you configure devices, you should attach all peripherals and restart the system with the reconfigure option (boot -r or reboot -- -r).

• If you remove or replace adapter cards, remove all device files that are associated with that adapter card.

• If you use the Automated Cartridge System (ACS) robotic software, you must ensure that the Solaris Source Compatibility Package is installed. The package is required so that the ACS software can use the shared libraries in /usr/ucblib.

• Oracle systems with parallel SCSI host bus adapters do not support 16-byte SCSI commands on any devices that are attached to these HBAs. Therefore, those HBAs do not support WORM media. To override this limitation, create a touch file as follows:

  touch /usr/openv/volmgr/database/SIXTEEN_BYTE_CDB
