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.
