Could someone give me some hints on what this is and how to fix it? I have BackupExec 12 SP1 with all the latest patches/drivers. I have a 6 drive library, and every drive is ready, but sometimes when I submit a job I get Ready; no idle devices are available. It seems to be happening on the jobs with Pre-command more often. For example. I start two jobs at the same time. Both have pre-commands. The 1st one will start with no issue, running its pre-command. The 2nd job just sits there stating "Ready; no idle devices are available".. I'm not even asking for a device yet! It should just be running it's pre-command. Nevertheless.. As soon as the pre-command finishes on the first job, the 2nd one will start up. Please help, thanks.
