PowerFile "Illegal SCSI CDB Value"
Error: illegal SCSI CDB value message is displayed in the log during an InveStore system startup.
If the PowerFile changer erroneously believes that the destination element address is full when it is not, then a quick fix is to go the front panel and try ejecting the destination element.
Doing an eject from the front panel on the slot in question will solve the problem if there is actually a disc in that slot or if the changer just thinks there is a disc in that slot and there isn't.
If that doesn't fix the problem, then the customer should contact PowerFile customer support at 1-877-838-3639. A support engineer there will be able to guide them through more diagnostics.
