Since there hasn't been any reaction to this, I'll add some more info and questions..
Is anyone using a SDLT tape drive on Linux? Searching the archives I couldn't find any evidence of SDLT use. Perhaps it needs some special parms? Are there any tape related options besides the erg and blkid parms?
When I got the "device or resource busy" error, I used the Linux fuser command (fuser /dev/nst0) and got a null response, suggesting that Linux thinks the device is not in use.
I appreciate any help...
