data_dev_writer : process writing to data device on primary and producing a protocoll containing statistics
|

about runtime and written data.
|

|
|
device cksum : checking that cksum primary = cksum secondary
|
||
|
|
|
||
|
|
recovery procedures : Some testcases cause more or less serious crashes or standstills (e.g. A4.1 below). If
|
||
|
|
there are documented repair strategies they will be tested, too.
