3.5 IBM System z: Hard Disk Configuration

When installing on IBM System z platforms, the language selection dialog is followed by a dialog to configure the attached hard disks. Select DASD, Fibre Channel Attached SCSI Disks (ZFCP), or iSCSI for installation of SUSE Linux Enterprise Server.

After selecting Configure DASD Disks, you are presented with an overview listing all available DASDs. To get a clearer picture of the available devices, use the entry field located above the list to specify a range of channels to display. To filter the list according to such a range, select Filter. See Figure 3-1.

Now specify the DASDs to use for the installation by selecting the corresponding entries in the list then clicking Select or Deselect. After that, activate and make the DASDs available for the installation by selecting Perform Action Activate (see Figure 3-2). To format the DASDs, select Perform Action Format right away or use the YaST partitioner later as described in Partitioning with YaST.

Figure 3-3 IBM System z: Overview of Available ZFCP Disks

To use ZFCP disks for the SUSE Linux Enterprise Server installation, select Configure ZFCP Disks in the selection dialog. This opens a dialog with a list of the ZFCP disks available on the system. In this dialog, select Add to open another dialog in which to enter ZFCP parameters (see Figure 3-3).

To make a ZFCP disk available for the SUSE Linux Enterprise Server installation, use the entry fields Channel Number, WWPN (World Wide Port Number), and FCP-LUN to specify the parameters identifying the corresponding disk. When you are done, exit the ZFCP dialog with Next and the general hard disk configuration dialog with Finish to continue with the rest of the configuration.
