RD1000's don't (in my experience) work that well with BESR. BESR's service "locks" the drive, and you cannot "eject" a cartridge while the BESR service is running. Stopping the service permits ejection.
This is a HUGE problem for anyone wanting to run BESR and have offsite bare-metal capable recovery points in convenient form.
I have spent all day on the phone today with Dell's Enterprise support (PowerEdge 2900 server, with Dell-shipped RD1000 drive and BESR 7.0 SBS Edition) and no one has been able to give any answers.
As far as I'm concerned, BESR is VERY problematic with RD1000's and fails our initial compatibility testing.
Someone over at SYMC needs to get one of these drives in and test with it--especially when you're dealing with rotations which require cartridge swap and removals.
