Device management best practices
The following items are device management best practices:
Monitor the NetBackup system log for device errors encountered.
Monitor devices by using the NetBackup Device Monitor.
Investigate the causes of all the drives that are down.
Do not use the robotic test utilities while running backup or restore jobs.
Read the NetBackup Device Configuration Guide before configuring devices on media servers (or SAN media servers). See the NetBackup Device Configuration Guide at the following URL:
Use only computers, operating systems and devices that Veritas supports. For supported devices, see the NetBackup hardware compatibility list on the NetBackup support site.
Use only fully-serialized devices. A fully-serialized SCSI library should report a serial number for the robot and also a serial number for each drive in the robot.
Always configure and use pass-through paths for robotic libraries and drives.
When possible, use SCSI persistent reserve or SCSI reserve and release.
Use persistent bindings for fibre-attached devices.
Use the NetBackup Device Configuration Wizard to configure the devices.
Download and install the latest device mapping file from the NetBackup support Web site before you use the NetBackup Device Configuration Wizard.
Use consistent logical drive types for all physical drive types on all servers in the environment. For example, use the DLT drive type as the logical drive type for all DLT7000 drives.
Do not load vendor medium-changer drivers on Microsoft Windows hosts. The default Microsoft medium-changer driver is acceptable (but is not required) for use with NetBackup.
