Some time ago (I’ve seen it after updating symantec backup exec to version 2014, but it may have started a little earlier) I noticed that some slots in the library HP MSL 4048 are shown as available and some are shown as «Cleaning media», although there are regular-recorded cartridges in these slots. If I scan the library, the available slots cassettes are shown as «Unknown media». To be able to use these «Unknown media» and «Cleaning media», I run «Quick Erase». The information about the tapes is shown correctly after erasing.
The same problem I noticed at the virtual disk library HP VLS 9000.
HP MSL 4048 we have been using for 4 years and didn’t have such problems before.
Because of this problem, if I do not manually erase tapes, most of them will be «Unknown media» and «Cleaning media» after some time. So I will not have enough space for backups.
I need a solution
