Gordon, According to what I read in the Distributions Redbook, "ntibm0" is the _first_ non-rewinding tape drive, and "ntibm1" would be the second one. So, if you only have one, you should probably be using "ntibm0" as the device: Since Linux for S/390 distributions may not include any tape devices, the following commands may be used to create a Linux device for each available tape device: #mknod /dev/rtibm0 c 254 0 (first rewinding character device) #mknod /dev/ntibm0 c 254 0 (first non-rewinding character device) #mknod /dev/btibm0 b 254 0 (first block device) #mknod /dev/rtibm1 c 254 1 (second rewinding character device) #mknod /dev/ntibm1 c 254 1 (second non-rewinding character device) #mknod /dev/btibm1 b 254 1 (second block device)
How that corresponds to Sergey's success using ntibm1, I don't know. But, it may be worth a try.
