Version: 7.0.5, own build
Storage device: Autochanger with two drives
Device config: see below
Expected behaviour:
After I unmount a tape drive, a "status sd" in bconsole should give the status
"Device is BLOCKED. User unmounted.\nDrive 0 is not loaded.". If I unmount all
devices attached to the changer, no backup should be able to start.
Observed behaviour:
If "Always Open = yes" in sd config:
(1) I unmount a "empty" device and get the response "3901 Device ""LTO0"
(/dev/nst0)" is already unmounted.". But "status sd" yields only
"Drive 0 is not loaded.", w/o the "BLOCKED" line.
(2) All devices are empty on sd startup and I unmount all of them. Status
as in (1). Afterwards I start a backup and the first tape is happily used.
(3) To get a "BLOCKED" status from sd, I need to mount and unmount a device if
the device is empty at sd startup.
If "Always Open = no" (as in the config snippet from below):
sd status always says "Drive 0 is not loaded." or "Slot xx was last loaded in
drive 0.". Backups always start, regardless of device mount state.
For the "why" part - no idea. I can also attach complete bconsole output, but
this would be quite a lot. But if it would help or if you need further infos,
just ask.
