Install xenserver on iscsi target

  • 772

Is is know that Xen Server is based on CentOS, and it is fact that CentOS can be installed on an ISCSI target flawlessly, but I wanted to install Xen server on an ISCSI target I couldn't find a way.

I already tried the latest version of xen server 6.2, and there is no obvious way who to do the installation without a local disk.

Does anybody have an idea about the subject, or did someone know how to do it?

Please share your experience about this subject.

    Installing to an ISCSI target is similar to installing to a local disk.

    You should be able to set your iscsi target as "First HDD" in the iscsi initiator settings.

    Additionally, make sure that you have a boot order of:

    1) iscsi target (DO NOT ALLOW IT TO BOOT TO THIS TARGET DURING INSTALL) (You should be able to set the target to mount but skip booting 1 time in the initiator settings)

    2) CD-Rom drive.

    The system should them mount the target, then boot to CD-ROM.

    After booting the to the Xen Server Install Media

    • At Xenserver installer boot press F2 to go to Advanced Mode
    • Type 'shell' at the prompt

    • At the prompt type: (Where "iqn.2010-01.com.example:name" is your IQN name)

      echo "InitiatorName=iqn.2010-01.com.example:name" > /etc/iscsi/initiatorname.iscsi

    • Initialize your target ("--mpath" if you have multipath setup to the iscsi LUN)

      /opt/xensource/installer/init --use_ibft
