    no iscsi-disk on client


    Hi Guys
    iscsi-client OS: SLES10SP3i586

    I configured this sles10sp3 box an iscsi-client via YaST (yast2 iscsi-client), but 'lsscsi' or 'fdisk -l' doesnt show any iscsi-disk

    # rcopen-iscsi restart

    even I unconfigured iscsi-client via YaST, and did things from command line, but again no success

    and then

    and still no iscsi-disk appear/available/visible

    Are you sure your target is presenting any LUNs to this client in the first place?
