Error Code
Description
1 EPERM General: The process does not have adequate permission to perform the desired function.
5 EIO Open: An I/O error occurred that indicates a failure to operate the device.
Write: The physical end of medium was detected, or it is a general error state indicating a
failure to write to device.
IOCTL: An I/O error occurred during the operation.
Close: An I/O error occurred during the operation.
6 ENXIO General: The device has not been configured and is not receiving requests.
Write: A write operation was attempted after the device had reached end of medium.
9 EBADF General: A bad file descriptor was passed.
Write: A write operation was attempted on a device that was opened for read only.
11 EAGAIN Read: The device is already opened.
12 ENOMEM General: Insufficient memory available for some internal memory operation.
Read: The number of bytes requested in a read of a variable block record was less than the
size of the block. This is referred to as an over-length condition.
14 EFAULT General: A memory failure occurred due to an invalid pointer or address.
16 EBUSY General: An excessive busy state was encountered.
Open: The device is reserved by another initiator or an excessive busy state was
encountered.
22 EINVAL Open: The operation requested had invalid parameters or an invalid combination of
parameters.
Write: The operation requested had invalid parameters or an invalid combination of
parameters, or the number of bytes requested in the write was not a multiple of the block size
for a fixed block transfer, or the number of bytes requested in the write was greater than the
maximum block size allowed by the device for variable block transfers.
28 ENOSPC Write: A write operation failed because it had reached the early warning mark while running
in label processing mode. This return code is only returned once at the moment early warning
is reached.
46 ENOTREADY General: The device is not ready for operation or a tape is not in the drive.
Open: If not opened with the O_NONBLOCK or O_NDELAY, the drive is not ready for
operation or there is no tape in drive. If the non-blocking flags are used, the drive is not ready
for operation.
47 EWRPROTECT Open: An open operation with the O_RDWR or O_WRONLY flag was attempted on a
write-protected tape.
Write: A write operation was attempted on a write-protected tape.
IOCTRL: An operation that would modify the media was attempted on a write-protected tape
or a device that was opened for O_RDONLY.
