Hi, 

I wonder if anyone can help. We run Networker 7.1 with a Windows 2000 
client that we are backing up via NDMP to LTO-2 drives. The backup starts, 
loads a tape into the drive, and verifys the label. Then it gives the 
error messages "failed to close NDMP tape device,SCSI device is not 
open", "failed to open NDMP tape device, I/O error" before hanging the 
jukebox on unload retry errors.  

Although this backup has worked in the past. I believed it was a timing 
error that probably needed the Unload Sleep, Load Sleep, Eject Sleep 
settings to go up to 180 Seconds. from 5. I changed the settings but still 
the same errors. 

I'm thinking it could be the LTO drive itself that might need changing but 
all the other non-NDMP backups work fine through that drive. 

Thanks for any help,

Martin.
