How to make one local storage from three partitions on different drives in Citrix Xen Server?

Question

XenServer

There is a Citrix Xen Server and 3 partitions on different disks (/dev/sda2, /dev/sdb2 and /dev/sdc2), local storadge is done like this:
#xe sr-create host-uuid=[TAB] content-type=user type=lvm device-config:device=/dev/XXX shared=false name-label="Local storage 1"
And how to combine these 3 partitions and make one local storage out of them?
Alternatively, you can assemble LVM from these three sections in the console, but then how can you make it available to the xen server?
Thanks in advance.

Create partition table on new disk: Create new LVM volume: Attach volume to volume group: we need volume group ID: VG_XenStorage-ece12464-dfb3-8c83-36dd-e88c9f2c6b65
# fdisk /dev/sdb
