Appendix A, Media Manager Reference Topics
The Media Manager Configuration File (vm.conf)
323
The minimum for number_of_seconds is 1. The maximum is 180. A value of zero is
converted to 1 second. The default value is 15 seconds. Using a value greater than the
default will delay mount requests and the displaying of drive status information in the
Device Monitor.
Caution Setting number_of_seconds to a value that allows media to be changed within one
scan cycle could cause NetBackup to be unaware of a media change and cause a
loss of data.
AVRD Pending Status Delay
AVRD_PEND_DELAY = number_of_seconds
If this entry is specified in
vm.conf
,
avrd
will wait number_of_seconds before displaying a
pending status (PEND) in the Device Monitor. This entry is read and interpreted on the
host where
avrd
is running.
Some server operating systems (Windows, Tru64, and HP-UX) report PEND if the drive
reports Busy when a volume is unmounted. You can use this entry to minimize the
display of this misleading status.
The minimum for number_of_seconds is zero. The maximum is 255. The default value is 180
seconds.
Backup Exec - Mapping Media Types
backup_exec_media_type = netbackup_robot_number netbackup_media_type
If this entry is specified in
vm.conf
, you can map Backup Exec media types to NetBackup
media types. This entry is used with the Backup Exec tape reader feature and can be used
when a NetBackup robot has different drives of a similar type configured. This entry is
read and interpreted on the host where
bephyinv
or
beconv
is running.
For example in a Backup Exec configuration, you have a robot with two DLT drives. Both
drives are considered to be DLT and all media in this robot have a media type of BE_DLT.
You plan to move your Backup Exec media to be used with NetBackup.
In your NetBackup configuration, you have a different robot (robot 1) with two DLT
drives. One drive is configured as DLT (Drive0) and the other drive is DLT3 (Drive1). The
Backup Exec DLT media type can map to DLT or DLT3.
If a backup_exec_media_type entry is not specified, the Backup Exec media type will be
mapped to the media type of the drive with the lowest index. Based on information not
shown for this example, Drive0 is determined to have the lowest drive index. Drive0 is
DLT, so Backup Exec media type DLT will be mapped to the NetBackup media type DLT.
(This is equivalent to specifying
BE_DLT = 1 DLT
.)
