No. Meaning
22 The parameter or buffer address is out of bounds. Typically, this means that the specified
buffer address is out of bounds.
26 You called AWAITIO while there were no outstanding nowait I/O operations.
28 This operation would exceed the number of outstanding nowait I/O operations allowed on the
specified file. For the Exchange/SNA line server, only one outstanding nowait I/O operation is
allowed on each subdevice.
31 The required buffer space is not available.
40 The time limit you specified in AWAITIO elapsed before the I/O operation completed. This
can also indicate other file-system time-out errors.
49 The attempted operation violates the type of access allowed with the specified file. Typically,
this means you attempted to write to a file you opened for read-only access or to read a file
you opened for write-only access. This error can also indicate a security violation; that is, the
file is not secured correctly for the type of access you requested.
60 The mounted volume does not contain the specified file, or the device was down and then
was brought back up before the I/O operation completed.
66 The device is down.
100 The device is not ready.
120 You attempted to send data (or receive data from the host) that is invalid in a nontransparent
data stream.
122 A possible loss of data occurred.
124 A reset of the line or subdevice is in progress.
140 A modem error, such as an unexpected loss of the carrier detect (CD) signal, occurred.
156 An I/O process protocol error occurred.
157 An I/O process internal error occurred.
159 The device is in the wrong mode for the requested operation. Generally, this error indicates
you should have specified COMPRESS NONE. The error means that you requested
incompatible parameters for an operation, such as specifying COMPRESS ALL for a send
operation when the line server is set up to transmit transparent data streams.
183 The session has ended.
200 The device is owned by the other port.
201 The system is unable to communicate over this path.
210 Ownership of the device changed during the operation.
211 The CPU failed during the operation.
218 An interrupt timed out.
219 An illegal reconnect occurred.
