Error Conditions for Serial DASD Subroutines

In addition to those errors listed, ioctl, open, read, and write subroutines against this device are not successful in the following circumstances:

EACCES	Indicates that an attempt was made to open a device currently opened in Diagnostic mode.
EACCES	Indicates that an attempt was made to open a diagnostic session on a device already opened.
EACCES	Indicates that an attempt was made to open a device whose parent device is currently opened in Diagnostic mode.
EACCES	Indicates that an attempt was made to open a diagnostic session on a device whose child devices are already opened.
EACCES	Indicates that a diagnostic ioctl operation was attempted when the device was not in Diagnostic mode.
EACCES	Indicates that a daemon ioctl operation was attempted by a process other than the RAS configuration daemon, or the adapter has not been opened by the daemon.
EBUSY	Indicates that the target device is reserved by another initiator.
EBUSY	Indicates that the other initiator may have outstanding requests queued to the device.
EBUSY	Indicates that a device cannot be unconfigured if it is still in use.
EFAULT	Indicates that a severe I/O error occurred during an adapter download.
EINVAL	Indicates that the read or write subroutine supplied an nbyte parameter that is not an even multiple of the block size.
EINVAL	Indicates that an unsupported ioctl operation was attempted.
EMEDIA	Indicates that the target device has indicated an unrecovered media error.
ESOFT	Indicates that the target device has indicated a recovered media error.
ENXIO	Indicates that the ioctl subroutine supplied an invalid parameter.
ENXIO	Indicates that a read or write command was attempted beyond the end of the disk.
EIO	Indicates that the target device cannot be located or is not responding.
EIO	Indicates that the target device has indicated an unrecovered hardware error.
EPERM	Indicates that the attempted subroutine requires appropriate authority.
ETIMEDOUT	Indicates that an ioctl operation timed out.
ENOMEM	Indicates that there is insufficient memory to perform the request.
ECHILD	Indicates that there are no more asynchronous events needing processing by the RAS configuration daemon.
