SYMPTOMS
After you use Windows Explorer to eject a magneto-optical disk from a drive in a Plasmon M series library, Removable Storage Manager (RSM) is no longer able to move media in the RSM media library.



CAUSE
This issue can occur because ordinarily, RSM handles moving media within a library. Moving a disk out of a drive and back to a storage slot should be done through RSM. Although you can use Windows Explorer to eject a magneto-optical disk from one of its drives, this interferes with RSM's ability to command the library to move media. When you use Windows Explorer to eject a magneto-optical disk, the disk blocks the vertical path sensors in Plasmon M series libraries. The storage device's picker is not allowed to move when these sensors are blocked. When this happens, RSM cannot move the transport, and the library is unusable.



WORKAROUND
To work around this issue, the operator must open the media library and either push the disk back into the drive, or remove it from the drive or library. Putting it back in the drive is probably the most desirable because the library still thinks the drive is full. After you do so, the library can continue on without any SCSI commands to the library. If the operator chooses to remove the disk from the drive or library, or remove it and then put it into a slot, RSM must then inventory the media library to detect the change.
