In order to troubleshoot the problem, kindly carry out the following steps.
1) Changing the medium changers present SCSI target ID 6 to one of the SCSI IDs 2-5 may resolve the issue.
Explanation:
The SCSI target ID 6 is reserved for automatic configuration of SCSI devices (through plug & play SCSI a.k.a. SCAM). This a system which offers automatic assigning of SCSI IDs to devices, without user intervention.
This system is, however, not supported by all hardware manufacturers.
The general recommended SCSI IDs for tape drives are 2,3,4,5.
IDs 0 & 1 should be reserved for bootable devices such as hard disks.
After changing the SCSI ID re-initialize the robotic library,to perform reinitialization follow the steps below:
- Power cycle tape library and the server (reboot)
- Perform inventory of each slots separately.

As an additional information please refer to the following steps.
a) Title:- The error "0xA000821 - Library Error - incompatible storage media detected in robotic library" occurs when an inventory is run against the robotic library.

b) Title:- When using multiple drives with multiple media types in some StorageTek libraries, the error "Incompatible storage media detected" can occur.
