GIT – Actually that’s pretty straight forward and the first thing you have to do is to add a new physical hard drive in your host. After that you boot up your again and go to the CLI.

[Side note: Red marked entries have to be changed with your own parameters or can differ from my entries. Also the you have to enter on the CLI are marked bold.]

On the XenServer CLI you have to list your physical disk with fdisk.

fdisk -l
Disk /dev/sda: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sda1 * 1 499 4008186 83 Linux
/dev/sda2 500 998 4008217+ 83 Linux
/dev/sda3 999 30401 236179597+ 83 Linux

Disk /dev/sdb: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdb doesn't contain a valid partition table

There you can see your new hard drive. In my case it shows up as /dev/sdb. For integrating the hard disk into your XenServer you first have to reveal the UUID of your host. This is done by the following command.

xe host-list
uuid ( RO) : ba3d140c-3de5-499b-b831-7c40d82958a9
name-label ( RW): xs-tarenz01
name-description ( RO): Default of XenServer

The last step is to create a new XenServer storage repository. You have three options for doing so.

First option: create a normal LVHD storage repository. This is by the way the default storage repository type.

xe sr-create host-uuid=ba3d140c-3de5-499b-b831-7c40d82958a9 content-type=user type=lvm device-config:device=/dev/sdb shared=false name-label="Local storage 2"

Second option: Create a LVHD storage repository with thin provisioning support.

xe sr-create host-uuid=ba3d140c-3de5-499b-b831-7c40d82958a9 content-type=user type=lvm device-config:device=/dev/sdb shared=false name-label="Local storage 2" sm-config:allocation=thin

Third option: Create a EXT storage repository with thin provisioning support and direct access to the vhd files.

xe sr-create host-uuid=ba3d140c-3de5-499b-b831-7c40d82958a9 content-type=user type=ext device-config:device=/dev/sdb shared=false name-label="Local storage 2"

…and finish. Now you have added an additional storage repository on your newly added physical hard drive to your XenServer.
