Chapter 4, SAN Configuration for ServerFree Agent 63

Create Offhost Backup Configuration Files

- “dev type 3h CNSi” indicates a Chaparral device. Its device path in this

example is

/dev/sg/c6t4l0.

◆ An alternative: the mover.conf file can consist of one line specifying the device by

means of the /dev/rmt/device_file_name, where device_file_name specifies the

actual file name of the device. Note that the tape device you specify must be the same

as the device that NetBackup selects for the backup.

◆ Another alternative: if the third-party copy device is a tape drive, the mover.conf

file can consist of a single entry: TAPE. For more information, refer to “Keywords in

Mover File,” below.

For sites that have multiple third-party copy devices

◆ In the mover.conf file, if you want to specify one of the third-party copy devices and

prevent the others from being used, specify the device by means of its sg or sctl

driver device path (such as /dev/sg/c6t1l0 on Solaris or /dev/sctl/c6t1l0 on

HP-UX), or specify its /dev/rmt/device_file_name.

◆ If you want to use any available tape drive that is third-party-copy capable, specify

the TAPE keyword. For more information, refer to “Keywords in Mover File,” below.

◆ If you want to limit the third-party copy device to that of a particular vendor or type,

while including a variety of devices in the file, use the END keyword. First enter the

device(s) you want to use, followed by END, then specify any other devices you

might want to use at another time. For more information, refer to “Keywords in

Mover File,” below.

Keywords in Mover File

The following keywords can be included in the mover file:

TAPE

The TAPE keyword tells NetBackup to attempt to use the current tape device if that device

has third-party copy functionality. This has two advantages:

◆ There is no need to specify a device path or passthru driver device path. Instead,

NetBackup uses the assigned tape device if it has third-party copy capability.

◆ Allows better concurrent backup processing, so that two or more backup jobs can

execute simultaneously.

Note To use a tape unit as a third-party copy device, a SCSI passthru device path must

have been configured for that tape device.
