Taking a Silo Inventory

Take inventory of the volumes in a silo to make sure that the mapping between slot number and volume name is correct or to reconcile the volumes in a silo with the list of volumes in the Backup media database.

The slot number of a silo volume is not a numbered slot inside the silo, as it is in an autochanger. The slot number of a silo volume is the number of the volume's position in the list of volumes in a silo. You can view the slot number for each silo volume in the Backup administration program in the Jukebox Mounting dialog box.

Use the Backup administration program or enter the nsrjb-I command to inventory a silo. Backup examines all the volumes in the silo and compares the new list of volumes to the Backup media database. Then Backup produces a message listing any volumes located in the silo but not in the media database.

When Backup inventories a silo, the silo's barcode label reader reads the barcode labels on the outside of each volume. When a barcode matches an entry in the Backup media database, Backup does not need to load the volume into the device and read, and the inventory proceeds very rapidly. However, if Backup reads a barcode that does not match any of the entries in the media database, the volume must be mounted and read for a proper inventory.

You can inventory a range of slots or barcode labels if you are pressed for time and do not want to inventory all the volumes in your silo.
