Use the sr-create command to create an EqualLogic SR. For example:
xe sr-create host-uuid=<valid_uuid> content-type=user \
name-label=<"Example shared Equallogic SR"> \
shared=true device-config:target=<target_ip> \
device-config:username=<admin_username> \
device-config:password=<admin_password> \
device-config:storagepool=<my_storagepool> \
device-config:chapuser=<chapusername> \
device-config:chappassword=<chapuserpassword> \
device-config:allocation=<thick> \

EqualLogic VDI Snapshot space allocation with XenServer EqualLogic Adapter
When you create a SR using the EqualLogic plug-in, you specify a storage pool in which the SR is created.
This assumes that the free space in the storage pool will be used for creating the VDIs, and for snapshot and
clones when requested. If the storage pool comprises of all the "member arrays" in the EqualLogic group
