      After replacing a failed disk in a ScaleIO Ready Node VD can not be recreated using "perccli add vd" command.   




      The issue might occur after physical disk replacement in the Node.   




      When following the disk replacement procedure one of the steps is to create a VD on the replaced drive.   


      The VD create command is failing even if the disk is in the correct state (UGood), not detected as foreign (state "UBad F" - see storcli add vd command complains "physical disk does not have appropriate attributes") and there is no Preserved cache on the VDs (see: storcli commands not effective):   

      [root@node ~]# /opt/MegaRAID/perccli/perccli64 /c0 show (...)32:11    11 UGood  -   1.090 TB SAS  HDD N   Y  512B HUC101812CSS204  U(...)    
      [root@node ~]# /opt/MegaRAID/perccli/perccli64 /c0 add vd type=raid0 drives=32:11 direct wb ra pdcache=offController = 0Status = FailureDescription = physical disk does not have appropriate attributes    
      [root@node ~]# /opt/MegaRAID/perccli/perccli64 /c0 show preservedcacheController = 0Status = SuccessDescription = No Virtual Drive has Preserved Cache Data.    






In this particular case, the replaced disk didn't seem to be inserted correctly, so it had to be re-seated.                                                           






The issue might occur after physical disk replacement in the Node.                                                           






Physically pull out and then insert again the replaced disk into its slot.
