Summary	0000174: "Status slots"says "0 slots" the first time after tapes were removed. Rerunning "status slots" then is correct.
Description	When removing tapes from a library, the first status slots afterwards says 0 slots. The second call is successful then. Maybe we could rerun the "status slots" call of mtx-changer once when 0 slots are reported.
Tags	No tags attached.

mvwieringen 2013-05-18 11:15 developer ~0000430	Essential this is a bug in the firmware as on a SCSI inquiry for the element status the library trows an error. So this should also be logged as bug with Tandberg. Other then that we can of course add one retry to see if we then get a better number of slots as 0 slots is not really an valid answer for any autochanger.

~~mvwieringen adm~~ 2013-08-13 03:12 administrator ~0000578	Fix committed to bareos bareos-13.2 branch with changesetid 1044.

pstorz 2013-09-06 16:55 administrator ~0000660	Tested on 12.4.5 and works.

joergs 2015-03-25 19:18 developer ~0001524	Due to the reimport of the Github repository to bugs.bareos.org, the status of some tickets have been changed. These tickets will be closed again. Sorry for the noise.
