Using the Physical Inventory Utility for Non-Barcoded Media
292 NetBackup Media Manager System Administrator’s Guide for Windows
It is not recommended to use a robot inventory update action for non-barcoded media
unless it is the initial population of the volume database. For non-barcoded media, the
second action is the recommended way to inventory the robot.
a. Add volume records to the Media Manager volume database. This can be done
using the Add Volumes or Robot Inventory Update interfaces. After the volume
records are added, you can use
vmphyinv
to physically inventory the robot
specifying only the robot number.
or
b. Use the slot range or list option of
vmphyinv
to perform the inventory operation.
You do not need to add volume records to the Media Manager volume database.
◆
Some of the media are misplaced and the Media Manager volume database does not
reflect the correct physical location of these media.
In these cases, you can inventory the whole robot or choose to inventory a subset of
media in the robot with options in
vmphyinv
.
◆
Media with unknown media IDs or GUIDs are inserted into the robot.
For example, you insert 10 media from a different tape library in slots 11 to 20 and you
do not know the media IDs on the tapes. One method to inventory only these 10
media follows:
a. Add volume records to the Media Manager volume database for these slots (you
can use any media ID in this case).
b. Move all the media to a separate volume pool, for example, inv_pool
c. Run
vmphyinv
specifying the pool name as inv_pool. Only the 10 media
belonging to this volume pool are inventoried.
A better way to inventory these 10 media is to specify a slot list/range in
vmphyinv
.
When used with a slot list/range option,
vmphyinv
mounts the media using the slot
information. When the tape header is read, the media ID can be determined. This
media ID is used to add a Media Manager volume record. This method avoids
unnecessary proliferation of media IDs like those added in step a.
How vmphyinv Performs a Physical Inventory
For a physical inventory, this utility performs the following sequence of operations:
1.
Obtaining a List of Drives Used to Mount the Media
2. Obtaining a List of Media to be Mounted
