ERRORS

The following errors may result from a call to a SCSI device driver:

[EACCES] Required permission is denied for the device or operation.

[ENXIO] If resulting from an open call, this indicates there is no device at the speciﬁed address.

For other calls, this indicates the speciﬁed address is out of range or the device may no

longer be accessed.

[EINVAL] If resulting from an open call, this indicates the device is not supported by the device

driver (e.g., incorrect device type). For other calls, this indicates the request or some

request argument is invalid. If resulting from the

SIOC_CAPACITY ioctl, one or more of

the ﬁelds in the argument structure may have overﬂowed.
