Problem

Media frozen upon getting "Medium identifiers do not match" errors when re-using barcode labels on pre-loved (with expired images) or new media
 

Error Message

From bptm log :

22:22:28.896 [1768.8912] <4> manage_drive_attributes: expected manufacturer [FUJIFILM], reported [FUJIFILM]
22:22:28.896 [1768.8912] <4> manage_drive_attributes: expected serial number [AC3AE1GTE9], reported [AC3ACF7CR4]
22:22:28.974 [1768.8912] <16> manage_drive_attributes: FREEZING media id ABC123, Medium identifiers do not match
 

Cause

The EMM_Media record keeps track of the following medium identifier info :

ManufacturerName
SerialNumber

Solution

 These are the steps to take when re-using barcode labels on pre-loved (with expired images) or new media :

1. Remove old media id to be re-used from Netbackup
2. Insert barcode label onto new tape/media
3. Perform robot inventory update (barcode rules may be required) to add new media id to Netbackup
4. If the new tape/media is actually a pre-loved Netbackup media, run bplabel command on this new media id to ensure it has the new media id recorded in its media header (See bplabel syntax for details)
5. The new media is now ready for use
