16.4. Installing in an LPAR

When installing in a logical partition (LPAR), you can boot from:
  • an FTP server
  • a DASD or an FCP-attached SCSI drive prepared with the zipl boot loader
  • an FCP-attached SCSI DVD drive
Perform these common steps first:
  1. Log in on the IBM System z Hardware Management Console (HMC) or the Support Element (SE) as a user with sufficient privileges to install a new operating system to an LPAR. The SYSPROG user is recommended.
  2. Select Images, then select the LPAR to which you want to install. Use the arrows in the frame on the right side to navigate to the CPC Recovery menu.
  3. Double-click Operating System Messages to show the text console on which Linux boot messages will appear.
Continue with the procedure for your installation source.

Note

Once you finish this procedure and one of the following ones depending on your installation source, the installation will begin. The installer will then prompt you to provide additional boot parameters. Required parameters are described in Section 16.1, “Customizing boot parameters”.

16.4.1. Using an FTP Server

    • User ID - Your user name on the FTP server. Or, specify anonymous.
    • Password - Your password. Use your email address if you are logging in as anonymous.
    • Account (optional) - Leave this field empty.
    • File location (optional) - Directory on the FTP server holding the Red Hat Enterprise Linux for System z, for example /rhel/s390x/.
  3. Click Continue.
  4. In the dialog that follows, keep the default selection of generic.ins and click Continue.

16.4.2. Using a Prepared DASD

  1. Double-click Load.
  2. In the dialog box that follows, select Normal as the Load type.
  3. As Load address, fill in the device number of the DASD.
  4. As Load parameter, fill in the number corresponding the zipl boot menu entry that you prepared for booting the Red Hat Enterprise Linux installation program.
  5. Click the OK button.

16.4.3. Using a Prepared FCP-attached SCSI Disk

  1. Double-click Load.
  2. In the dialog box that follows, select SCSI as the Load type.
  3. As Load address, fill in the device number of the FCP channel connected with the SCSI disk.
  4. As World wide port name, fill in the WWPN of the storage system containing the disk as a 16-digit hexadecimal number.
  5. As Logical unit number, fill in the LUN of the disk as a 16-digit hexadecimal number.
  6. As Boot program selector, fill in the number corresponding the zipl boot menu entry that you prepared for booting the Red Hat Enterprise Linux installation program.
  7. Leave the Boot record logical block address as 0 and the Operating system specific load parameters empty.
  8. Click the OK button.

16.4.4. Using an FCP-attached SCSI DVD Drive

This requires a SCSI DVD drive attached to an FCP-to-SCSI bridge which is in turn connected to an FCP adapter in your System z machine. The FCP adapter must be configured and available in your LPAR.
  1. Insert your Red Hat Enterprise Linux for System z DVD into the DVD drive.
  2. Double-click Load.
  3. In the dialog box that follows, select SCSI as the Load type.
  4. As Load address, fill in the device number of the FCP channel connected with the FCP-to-SCSI bridge.
