Yast2 dump module test proposal: 
 That module is a front-end for [mkdump]( It does this: 

     mkdump --list-dasd 
     mkdump --list-zfcp 
     mkdump [--force] /dev/[device] 

 Te mkdump modules automatically lists DASD or ZFCP device that can be used as dump device. Such device should be of ECKD type (mkdump [does not work with FBA](, this can be subject to a soft failure) it must have exclusive access and have VM's RAM+ 10MB of free space. 

 ## Acceptance criteria 
 1. Smoke test for yast2 dump module is enabled on s390x at least for SLE 15 SP2 

 ## Suggestions 

 **1 - Activate some DASD and/or ZFCP device:** 
 This can be done in various ways: 
 * During [installation](,  
 * Later by command line as in [bootloader]( (command: "dasd_configure 0.0.200 1". That disk should be free is is "dumpable".) 
 * By putting this test module after the ones for dasd and/or zfcp, which also allow to enable disks. 
 See also: the SUT for ZFCP, [s390x-zfcp]( 

 **2 - Start yast2 dump, initialize some disk for dumping.** 
 Don't forget to signal as soft-failure if an incompatible disk is shown here. 

 **3 - check if disk is marked as dump disk**, either in the module itself or with mkdump --list-dump
