Hello Xeven, The tape drives for an internal and library are slightly different than a external tape drives.  With an internal drive there are usually different firmware that tells the drive that there is a medium changer to move media.  With an external standalone drive, the firmware does not have the medium changer enabled.  If you set all the dip switches correctly and you are still not able to get the drive to login, then it comes down to the code that is on the drive that is set to external & not internal.  The code is set at the factory for the tape drives and can’t be flashed with a firmware upgrade. Please let us know if you have any other questions.
I've picked up a Dell/IBM LTO-5 HH drive from an external Dell enclosure. I've popped it into a spare LTO5 Sled, and tried to get it to run on the TL4000 (also a TL2000 with same result) but the drive doesn't seem to appear, even after a complete reset of the PV. The PowerVault does it's usual tape scans on boot, then seems to be trying to connect to the drive. About 15 minutes later, I get an error "HE: drive logged out Code: FB 01". From what I can tell, it's some sort of communication error between the PV and the Drive. I checked the cables on the sled, and made sure the LDI switch was on on the drive - Switch 5 of 8 - (all other switches set to off). Still having no luck. Usually, I am able to communicate with the drive over SAS from a PC, even when it's in the PV. The drive itself shows no errors, but the usual green "all good" light - even when it's in the PV. Am I doing anything wrong here? Is it a dead drive, PV or PV controller? Could I have the wrong switches set on the drive? Maybe a Firmware issue? If anyone has had this before or can help I'd appreciate it.
