HP Guardian Errors Manual page 47

Cause This error can occur for the following reasons:
A hardware data-parity error occurred and persisted through several retries of the operation.
The tape density is higher than the tape drive allows.
Effect On a disk or tape READ or READUPDATE, the procedure returns as much (invalid) data as
possible. You can determine the number of characters returned by checking the procedure count-read
parameter if the procedure is a wait read or the count-transferred parameter of AWAITIO[X] if it
is a nowait read.
Recovery If the device is a tape drive, clean the tape head and retry the operation. If this action
fails, try another tape.
Any other corrective action is device dependent and application dependent.
121 (%171)
Cause A hardware data-overrun error occurred and persisted through several retries of the operation.
Effect The procedure sets the error code and returns without performing the requested operation.
Recovery Corrective action is device dependent. Contact your service provider.
122 (%172)
Cause This error can occur for the following reasons:
A request aborted due to a possible loss of data caused by a circuit reset.
There is a sequence error in the CIU-to-LIU bus (CLB). This is a data communications error.
There is a DP2 process takeover.
This error occurs only on unaudited, buffered files with a sync depth equal to 0. The message is
returned once for each open of the buffered file. This message also can be returned on any call
that supplies a file number except for CLOSE, which never returns an error.
Effect The procedure sets the error code and returns without performing the requested operation.
Recovery Corrective action is device dependent and application dependent.
123 (%173)
Cause An operation was in progress on the specified subdevice.
Effect The procedure sets the error code and returns without performing the requested operation.
Recovery Corrective action is subdevice dependent and application dependent.
124 (%174)
Cause A line reset was in progress for the subdevice or line, possibly causing a loss of data.
Effect The procedure sets the error code and returns without performing the requested operation.
Data overrun error, hardware problem.
(device type: any except 2)
Request aborted due to possible data
loss caused by reset of circuit, CLB
sequence error (device type: 6, 7, 9, 11, or 61);
or DP2 disk process takeover (device type: 3)
Subdevice is busy.
(device type: 5, 6, or 10)
A line reset is in progress, loss of
data is possible. (device type: 6, 10, 51, 53, 59,
60, or 63)
