I have an external Dell PowerVault 110t connected to a Dell PowerEdge 700 server running Windows Server 2003. I’m using Windows backup to backup files and managing the tapes through Removable Storage Manager (RSM). The tape drive was previously connected to another Windows 2003 server and backing things up just fine but when I moved it to this other server, tapes are seen as Unknown (Read Only) and despite all my efforts, it won’t shake the read-only status.
I’ve loaded the driver from Dell and the only light on the drive is Power. There are no other SCSI devices on this system and I can eject/inject tapes from RSM so I know the drive and server are communicating. There is nothing in the event log indicating a problem. The properties of the drive show Enabled and tape is dismountable but the icon reflects a CD symbol. The system and RSM see the drive as a Quantum LTO1 Tape Drive. I’ve powered on/off the drive and rebooted the system after the new driver was installed. I’ve tried different tapes and they’re not read-only. I’ve even cleaned the drive with a tape made for that purpose. And nothing I’ve see through Google has led me to any fix.
Does anyone have any suggestions on how I can overcome this?
