Configuring a robot inventory filtering on ACS robots

If you want NetBackup to use only a subset of the volumes under ACS library control, you can filter the volume information from the library. To do so, you use the ACSLS administrative interface to assign the volumes you want to use to a scratch pool or pools. Then you configure NetBackup to use only the volumes in those scratch pools.

A NetBackup robot inventory includes the volumes that exist in the ACS scratch pool. The ACS library software moves each volume from the scratch pool after it is mounted.

A partial inventory also includes those volumes that NetBackup can validate exist in the robotic library, including volumes not in the ACS scratch pool. To prevent losing track of previously mounted volumes, the library reports the complete list of volumes that exist in the robotic library.

The following procedure is an example of how to configure an inventory filter.

To configure an inventory filter (example)

Use the ACSLS administrative interface (ACSSA) command to create a scratch pool. Assign ID 4 and 0 to 500 as the range for the number of volumes, as follows:
```
ACSSA> define pool 0 500 4
```
Use the ACSLS administrative interface (ACSSA) command to define the volumes in scratch pool 4:
```
ACSSA> set scratch 4 600000-999999
```
On the NetBackup media server from which you invoke the inventory operation, add an INVENTORY_FILTER entry to the vm.conf file. The following is the usage statement:
```
INVENTORY_FILTER = ACS robot_number BY_ACS_POOL acs_scratch_pool1 
[acs_scratch_pool2 ...]
```
The following define the options and arguments:
- robot_number is the number of the robot in NetBackup.
- acs_scratch_pool1 is the scratch pool ID as configured in the ACS library software.
- acs_scratch_pool2 is a second scratch pool ID (up to 10 scratch pools are allowed).
For example, the following entry forces ACS robot number 0 to query scratch volumes from Sun StorageTek pool IDs 4 and 5.
```
INVENTORY_FILTER = ACS 0 BY_ACS_POOL 4 5
```
