Failed Restoring data from tape. (V79-57344-33031)

Hi.

I use BackupExec 2012 V14.0 Rev.1798.

Making a restore-job, restore-items selected but there is no storage-item to select: What job name[,storage] and schedule do you want to use?

After running job, it failed with V79-57344-33031 - Unable to acquire device for specified pool and media.

Note: in the past the tapedrive has been replaced and BE has it automaticly assigned a new name.

After the failed restore-job I have cataloged the tapes with success, but making a new restore-job there is still no storage-item to select.

Why?

Thanks for helping.
