Note:
Due to incompatibilities with the integrated multipath management architecture, the standard dm- multipath CLI utility should not be used with XenServer. Please use the mpathutil CLI tool for querying the status of nodes on the host.
Note:
Multipath support in Equallogic arrays does not encompass Storage IO multipathing in the traditional sense of the term. Multipathing must be handled at the network/NIC bond level. Refer to the Equallogic documentation for information about configuring network failover for Equallogic SRs/LVMoISCSI SRs.
Storage Repository Types
The storage repository types supported in XenServer are provided by plugins in the control domain; these can be examined and plugins supported third parties can be added to the /opt/xensource/sm directory. Modification of these files is unsupported, but visibility of these files may be valuable to developers and power users. New storage manager plugins placed in this directory are automatically detected by XenServer. Use the
New storage repositories are created using the New Storage wizard in XenCenter. The wizard guides you through the various probing and configuration steps. Alternatively, use the
All XenServer SR types support VDI resize, fast cloning and snapshot. SRs based on the LVM SR type (local, iSCSI, or HBA) provide thin provisioning for snapshot and hidden parent nodes. The other SR types support full thin provisioning, including for virtual disks that are active.
Note:
Automatic LVM metadata archiving is disabled by default. This does not prevent metadata recovery for LVM groups.
Warning:
When VHD VDIs are not attached, for example in the case of a VDI snapshot, they are stored by default thinly- provisioned. Because of this it is imperative to ensure that there is sufficient
