Before I re-invent something that exists but I simply don't know about it, is anyone else using LTO tape on FreeBSD, especially with HP StorageWorks or Dell PowerVault juke boxes? With a single drive you can get away with mt and tar/dump as you prefer. It's also easy enough to dump a ZFS dataset to a tape device - although not documented (that's one of my first jobs). But when it comes to jukeboxes there's nothing I'm aware of - you can't even get at the tape label - either via the RMI or cam. Unless you know different? I haven't even been able to find programming documentation from HP or Dell, but some must exist as commercial backup products can do this on Windoze. Is there some huge cache of documentation I'm missing (pointer please!), or is anyone else working on this and able to join forces? BTW, I am aware of LTFS but it's not really useful in the BSD world, where archiving databases and datasets is more likely to be of interest. Thanks, Frank.
