dasd-eckd.f716c1 <bus ID of the DASD>: The storage server does not support raw-track access
Explanation
The DASD cannot be accessed in raw-track access mode because the storage
server does not have all required features for this access mode.
In raw-track access mode, the DASD device driver accesses complete ECKD
tracks.
By default, the DASD device driver accesses only the data fields of ECKD
devices and omits the count and key data fields.
User response
Ensure that the raw_track_access sysfs attribute of the DASD has the value
0 to access the device in default ECKD mode.
