◆ Future NetBackup features and enhancements

Enabling Passthru Paths

Several sg device files are provided by default in the typical Linux installation. If you have

more devices than the default number provided, you must create the required device files.

There must be a /dev/sgN entry for each device. These entries are needed by

make_scsi_dev, which is run during the NetBackup installation.

If you have devices that are not being discovered by Media Manager device discovery, it

may be because the Linux default number of these entries is not sufficient. You may need

to create additional entries.

Configuring Robotic Controls

To use robotics, the following drivers must be configured in the kernel or loaded as

modules:

◆ Standard SCSI driver.

◆ SCSI-adaptor driver.

◆ Linux SCSI generic (sg) driver.

Information on supported SCSI robots (vendor models) can be found on the VERITAS

support web site.
