Add Another Local Disk on XenServer as a new Storage Repository

Welcome to our guide for adding Local Disks as a new Storage Repository on a Citrix XenServer host. Yes, using network storage is a safer idea for many situations but there are some use cases where using local storage makes a lot of sense. For example, if you have data (like log files) that is disposable but can be quite large, saving it on a local disk is a totally reasonable thing to do.

In this guide, we’ll walk you through the process of adding local disks as a new storage repository on your Citrix XenServer host, enabling you to benefit from increased storage capacity and faster virtual machine performance.

  • From XenServer console:
    fdisk -l
    • that should return an error like this:
      Disk /dev/sdb doesn't contain a valid partition table
      your local hard drive is “/dev/sdb” or whatever the error the first command shows you
  • run this command:
    xe host-list
    • that will return something like this:
      uuid ( RO) : 3614fba9-f5fc-1c57-0b42-58413c51fc1c
      name-label ( RW): xenb
      name-description ( RO): Default install of XenServer
  • copy the UUID of your host server to the clipboard.
    xe sr-create host-uuid= content-type=user type=lvmohba device-config:device=/dev/sdb shared=false name-label="Local_Stor_2"
    • if you get an error you may need to unmount your current local storage in order to add the new one.
      to do this, run this command:
      xe pbd-list
  • get the UUID of your current storage
    run this:
    xe pbd-unplug uuid=
  • Try mounting your Hardware HBA through Xencenter.
  • This worked for us, hope it does for you too!
