dasd.68f0f6<bus ID of the DASD>: A transport error occurred for cqr <pointer to request>
Explanation
A channel queued request (cqr) failed because the connection to the
device was lost and the 'failfast' flag is set for the request.
This flag can result from, for example:
A software layer above the DASD device driver;
for example, in a host based mirroring setup.
Value 1 for the 'failfast' sysfs attribute of the DASD.
This setting applies to all requests on the DASD.
User response
Ensure that each channel path to the device has been set up
correctly and that the related physical cable connections are in
place. If the 'failfast' attribute of the DASD is set to 1,
verify that this setting is intentional and change it to 0 if required.
