Inventory jobs failing with: 0xe0008212 - Library error - invalid element address.
BE 12.5 SP4. I use removeable backup-to-disk folders on 3 separate hard drives that are swapped into the server periodically (weekly, monthly, etc). So at any given time, only one drive is mounted. Each time an untrained user swaps a drive, I run an Inventory job on all three drives (because the process is semi-automated, and doesn't know beforehand which drive was installed). I have this setup on four different and independent servers at different client offices and have been using the setup successfully for several months.
Until very recently, on all four servers, all of the inventory jobs would run successfully even though there was only one of the 3 drives actually mounted. However, within the last 2 weeks, on 3 of the 4 servers, the only inventory job that succeeds is the one for the mounted drive, and all the other inventory jobs fail with the message: 0xe0008212 - Library error - invalid element address. Oddly, on the 4th server all inventory jobs continue to succeed.
It seems benign, and in a way it makes more sense that only the drive mounted can be inventoried, but what has changed? As far as I can tell all 4 servers are at the same patch level. Is there, in fact, an underlying problem that I need to correct?
